Only on this channel can you witness two crazy brothers with a "WONKEL" engine crashing into the stands , living to tell about it and then hand tossing in front of the world. Yesssssssss Thanks for the pleasure guys. Russ
You close your eyes and listen for whatever small sound it might be... or... as the flames 🔥 shoot out the red glowing exhaust and you know that baby works right
I LOVE this new thumbnail opening video !!! You guys probably said HEY or EH 50 times at least and had me laughing again and again !! Congratulations, another milestone.... 16000 subscribers !!! Cheers from Canada !
dis IS it!!!!! this is my all time pick for the funniest vid O they have made. If there is a better, PUH LEEEESE tell us!!!!! Poor Robby is mad,embarrassed,and an all around great SPORT!!!!
Greeting guys from America. You all have to remember a thing called "Torque" when you rev RC engines and the Wankel's have a flywheel on the front that does give a lot of right-hand Torque or Left hand depending on the direction of the motor....counter that with a little left or right aileron in the future...!(This works for the Electric planes too) Love you guys vids and love the RC Hobby (22 years now)...!
The title says it all! I was just looking at BG for buying the balsa t tail glider kit and putting it together for my son over the really cold winter days. That engine is well above me, but I like seeing that engine and congrats for trying it and having fun.
Oh yeah , sounds great. Nice flying pilot Robert, I knew this engine would make plenty of power . Rotaries use tons of fuel but fast engines. What a bargain. Have a good weekend guys. Salute to you guys.
Great flying and awesome camera work. That engine sounded great. Cant wait to see it back in the air. Pilot Robert and Capt Blaz thanks for the video. Just having fun RC'n.
Hi. I enjoyed the show. I know you like the speed demons. This is an over-powered plane. That big wing will enjoy a soaring point of view. Slow speeds, loops and rolls. Flying so fast is a waste of this wing. I enjoyed the Wankel. It would do very well in the nose of one of those US Navy war birds. If you can, put it in a Hellcat!
Too much fun! Way cool and the motor is fast! Love it! Thanks. Ive built three airplanes and haven't flown any of them yet. So nervous! You give me the nerve to fly! Thanks! Remember, always keep your wings in the air! I will do the same, thanks.
What a maiden flight!! You said it Robert,you had it all in one flight!! That engine does sound great and will sound better the next time out with Captain Blaz tuning it.FRankie Boy does fly ok!!Maybe another airframe would be better for this fine little Wankel! Cheers guys,and have a great weekend!!
SALUTE! PERFECT FLIGHT! Wankel engine speed plane! You are priceless! That engine needs some more close up flybys to make our ears sing Hey! Plane in one piece is always good flight. Hey! Thank you again for your wonderful videos showing your love for our hobby! Salute! Carl Cgul
This video made me laugh because of the luck you had; a crash near your cars and Blaz, This is why every video you make is a pleasure to watch. Always unpredictable. Thanks again it’s great👍the wankel sound also.
These engines just sound the best oh yeah great video brothers. I would say the plane liked to climb because of the wing area and the speed it was going.
Take this nugget of wisdom from the glider CG test known as the "dive test". A glider is trimmed to fly straight and level. You then initiate a 45 degree dive and return the elevator stick to neutral. The aerodynamic forces on the tail increase, and tell the tale of the CG position relative to neutral. If the plane pulls up sharply, it is nose-heavy, and if it 'tucks' into the dive (nose-down), it is tail-heavy. The sweet spot is somewhere between neutral (continues down at the 45 degree angle), and slightly positive (pulls out of the dive gently). For a powered aircraft the equivalent is its behavior at speed vs trimmed, level cruise. Of course there are other factors including incidence and thrust-line. Some down/right thrust of course, and incidence close to 0 degrees is a good starting point. Good luck, and happy tuning!
I had one of those Wankel engines a few years back. They guzzle fuel, but they sure sound good, and they put out the rps'm and the power! As for the excessive climbing, if the CG is about 1/3 to 1/4 from the LE, then the plane might just need some down more thrust in the engine. 2 to 4 degrees is usually about right.
It is just too much power for the lift the wing produces at the wrong time. You have twice the power level of a "normal" 5cc engine coupled to a high lift platform- it will go nowhere but up. The roll out on takeoff wasn't due to any torque reaction- you have a lot of lift from the prop wash going clockwise (facing the nose) under the port wing no rudder and not enough effect in the ailerons to overcome it. Hand launch- point it down and heave it.
Be QUICK, HEY! Captain Blaz!! Frankie Boy lives on! It's a pretty good flyer once you get it away from the ground! I loved the sound of that engine! Pilot Robert, do NOT take Frankie over to the quarry.....I loved the flight.....good job Pilot Robert and Captain Blaz!
It was really crazy my friend but so thrilling. And I think also that this bird is not for the quarry flight ;-) Big salute to you from Slovenia and have great weekend.
Fast Frankendevil!! Find one of your crashed planes and put on a rudder, that will help it to be even more Frankie boy. Great to see you fellas. I think Blaz isn't really disappointed that he does not get engine. look forward to next time.
We should Call that an experimental Wild Ride Aaaa....Ha Ha....The wankel is a different sound Fore Sure Aaaa...But it is A Gas Guzzler Aaaa....lol But if flew well thanks to your Skill..Aaaa...👍 Excellent dead Stick landing...i knew she was running out of fuel when the Wankel cleaned up at the end...lol. Salute to you 👏👏
Hmmmm. Nice flight....? What prop and RPM were you getting? It still sounds a bit rich to me. Seeing as it is a glider, sort of, why not just fly really high and when it runs out of fuel see how long you can glide it around.
David McIntire - I agree, if it is light enough. It does need a rudder. Fly it high, run it out of fuel and perform dead stick aerobatics to the ground. Good fun flying.
Maybe yes, maybe no. Rudder is nice but not an absolute necessity. It is a lot easier to be a humble pilot and change yourself to fit the airplane and the way it is designed and it's flying character than it is to change the airplane to fit you.
Robert, that plane is pretty tuff, nothing broke after the first crash. Your lucky it didn’t hit your car or your brother. That would leave a mark. Another fun video,
Like you said my friend. I was really surprissed how good it can handle crash. Still it was great time filming this baby and so much fun. And this Wankel is just crazy for just 5cc. I love it.
It is well built for sure. The 5cc displacement really doesn't translate well between a wankel and a conventional piston engine. The actual power output is more akin to an engine twice that size.
This was really crazy this time. Iam really lucky that the bird survived to see another day. At the end it was great experience all over again. I love it. Cheers my friend.
Magnificent Pilot Robert and Captain blaz, you two had me in giggles again. " Its so oily " , pilot Robert says. " is it wet" ? Captain blaz asks. So funny chaps. Nice one. 😂😂😊😂
It was really crazy my friend and so much fun this time. I just love these kind of filming when you dont know what will happen. Perfect. And the engine is really amazing.
It is a well built plane! WooHoo. We have had many take off's like that and have hit each other many times! HaHaHaHaa. Now you will set the perfect expo. Great flying and video from the Petrincic Brothers! HaHaHaHaa. Ricky.
Great video and a great start for my day, great flying Pilot Robert, CPT Blaz maybe you need a helmet, great tuning of a classic motor, Jeff in LA USA That wire will always act like a trip wire grabbing the the grass flipping the plane on landings in the grass
The CG is always between 25% and 33% from the leading edge of any straight wing airplane and it's usually right at the thickest part of the wing (which is usually at the main wing spar). With a wing like this one where it is wider at the fuselage than it is at the ends, just use the thickest part of the wing to set the CG. You can also check it together by having Blaz put his finger under the thickest part of the wing tip, then you do the same at the other end of the wing. I promise, it works everytime! I have been flying models and full scale airplanes since 1987. BTW, It is different for swept wings and for biplanes. For swept wing and biplanes it requires some complex math and geometry. Also, this is basically a glider, yes it flies fast but it will also fly very slow, notice how long it floated on the approach to land without the engine running. You could easily use half or less throttle and it would still fly great because the wing loading is very low (ounces per square foot of wing area). At a slower airspeed, the controls would be much less sensitive as well. This plane was meant to still be a glider. It has a small tank for fuel so you get up high in the air, then when the fuel runs out, you can glide for a while with no power. If you add more weight by adding more fuel then it will be too heavy to use as a glider. If you only want to use it as a powered airplane then by all means add the rudder and more fuel. Of course I would probably try to figure out a way to add a rudder but that would add to the weight and wing loading. Also, you can't always use the amount of elevator trim to determine CG because the angle of incidence of the elevator may not be correct, those cheap Dynam airplanes are bad for not using the correct angle of incidence and many times their control surfaces are warped!!! Good purchase :-) All the best :-)
Thanks for great informations my friend. I was trying CG at 33% from the front and it felt so nose heavy but once in the air it was just crazy nose light. Still it was great experience and I didnt want to glide much becouse previous owner said that it needs speed to fly good. But like you said it glided really good when the engine died at the end so maybe next time I will try to take the bird high and the reduce throttle and glide down. And maybe we can fins some bigger fuel tank that will fit inside. At the end I can say that I have really enjoyed this flight and filming. And maybe I will put this engine on Fokker plane instead of that Magnum. Big salute to you from Slovenia, Robert
How do you determine whether it is nose heavy or tail heavy? What method? Please? And.....what percent of throttle do you use to set the elevator trim for level flight?
I always set CG from the manual and then I see how the bird flies at arround 65% of throttle. At that throttle it should fly in a straight line not up and not down. And then you see how much you must trim elevator and in which dirrection. But its always easier to fix CG if I have nose heavy bird and more easy to control the plane on maiden flight.
That is a very good way to do it my friend, that is the same way I set the CG for maiden flights, I always use 60 to 65% throttle to trim for level flight but I never use the elevator position or the trim position as a guide for the best CG position. I always use flight characteristics as the guide for best CG position. The final adjustment of CG depends on my own flying style (as long as it is within safe limits). Slightly nose heavy will insure that the bird is more stable on takeoffs and landings, and especially landings since a forward CG helps to prevent ballooning on approach to land and it helps to keep your bird from bouncing once it touches down on the runway. But, it is very important to make sure it isn't "TOO" nose heavy, otherwise the elevator will not be as effective at raising the nose and will likely tip over almost every time on landing, especially in grass. I have found that some manufacturers like Dynam are giving wrong CG positions in their instruction manuals (not really surprising, eh?) I will try to find a way to demonstrate flight characteristics of a plane that is too nose heavy as well as one that is too tail heavy so your viewers can have a better understanding of what is "TOO” nose or tail heavy and what it should look like when the CG is good.
I'm not an expert on the matter here but still feel the need to clarify a bit. The CG can be absolutely anywhere and simply depends on how the weight is distributed. Should it be anywhere? No, at least if you want your plane to be both controllable and stable at low speeds. Put it too fore and you don't have enough elevator authority to fly slow. Put it too aft and the airplane becomes (longitudinally) unstable in slow flight. So for each plane there's a range where your CG should be unless you're crazy. Now, a simple analysis reveals that if the CG is at or fore of what's known as the aerodynamic center (AC), the plane is longitudinally stable at all speeds. Which is nice. And for practical considerations the AC can be assumed to be at 25% chord. So put your CG at 25% chord or fore of that then the plane is stable at all speeds. But put it too much fore of 25% then your nice and now very very stable aircraft will run out of elevator authority when you try to fly slow (and make a nice landing). Of course you can modify your horizontal stabilizer / elevator to compensate but that will add drag (because the horizontal stabilizer is working against the lift generated by the wing). Put it aft of 25% and the plane becomes more sensitive to elevator, which may be nice, but also means there's now an airspeed below which the airplane becomes unstable. Too much aft and that limit occurs already around or above stall speed and may result in loss of control (and stall, making things worse) if you ever fly that slow (as you probably are when taking off or landing). So you'll probably want your CG to be somewhere near the AC for a nice balance between elevator authority and low speed stability. And for practical purposes that means putting the CG somewhere near 25% chord because the AC is not far from that. (If it actually exists. Which it really doesn't for real wings but that's not important now.) You can put it fore or aft but not too much. I guess that's where your 25% comes from. I have no idea where your 33% comes from though. For real airplanes 33% sounds a bit too far aft for comfort and may start to risk the stability in slow flight depending on the plane. I guess it doesn't matter quite as much for RC pilots because most RC planes aren't really ever flown critically slow. (Mine are, check my channel for a truckload of boring wingcam videos.) And if the wing is not a straight rectangular one but tapered/swept/delta? Which one of the infinitely many different chords to use? The answer: the mean aerodynamic chord (MAC).
HEY WHAT WAS THIS HEY. HEY. THAT BABY IS ONE TOUGH PLANE. HEY. THAT WANKLE SOUNDS AWESOME. NICE JOB ROBERT THE SECOND ATTEMPT WAS JUST PERRRRRFECT. AND A NICE DEAD STICK LANDING. HEY. THIS IS WHAT IT'S ALL ABOUT. THIS IS REALITY TV AT ITS BEST. THANKS GUYS
HO HO du bist nich Capten Blash du bist Capten Crasch. Ich liebe deine videos, darum dspas ich weis nie wie hat das beendet mit dem MODELL. Troz dem du bist Grosse Kampfer ,Capten Crash du must weiter kempfen. Mfg Miloš
Im pretty surprise that this plane flew so well. Waiting to get this 1600mm Spitfire ,but hearing the sound of this gas model makes me want to change my mind.
@@PetrincicBrosRC a rep told me that they will be back in stock in October, and in November they will have some sale on all products so you can try and source one then.
I apologize for just watching this video, I missed it somehow... the wenkel/rotary engine is great! From my understanding of the wenkel the displacement is actually in the power class of engines twice its displacement.. 1.3cc is close to 2.6cc in piston engines... The Mazda engine here in the US are like this.. The wenkel loves high rpm!!!
Only on this channel can you witness two crazy brothers with a "WONKEL" engine crashing into the stands , living to tell about it and then hand tossing in front of the world. Yesssssssss Thanks for the pleasure guys. Russ
You said that so good my friend. Thanks for all support. I will put this comment to the top. Perfect. Big salute to you from Slovenia, Robert
Does that mean I'm 1st ??? I'm always last ....
Oh yeah my friend. On top this time. Perfect.
Captain Blaz has an Rc magnetic personality he attracts the planes out of the sky for extreme close ups!!!
“Captain Blaz, camera on me...Hey!”
This is the best RC channel on UA-cam, honest and awesome!
Oh yeah, my famous words ;-) Thanks for such kind words and for all support my friend. Cheers, Robert
"Look at that sound" should have been followed by "listen to how good it looks" Blaz! 😉🤣
As a mechanic I have often said the same thing... it's part of the job
You close your eyes and listen for whatever small sound it might be... or... as the flames 🔥 shoot out the red glowing exhaust and you know that baby works right
awesome that you guys show these antique engines and they are flying in all there glory - just crazy sexy Hey , Salute !!
This is one of my favorite videos!
It was really crazy my friend but at the end the bird did survive to see another day ;-)
I LOVE this new thumbnail opening video !!! You guys probably said HEY or EH 50 times at least and had me laughing again and again !! Congratulations, another milestone.... 16000 subscribers !!! Cheers from Canada !
That was the best hand tossing I've ever seen Captain Blaz :) I Salute you both from USA gentlemen

fantastic sound and great flying I love that plane!!! SALUTE my friend from NZ :)
A rudder may be a good idea for ground take off and "G" spot may be out.Great fun video guys!
Wonderful build and flight, have an eye on that beautyful collectors item-the Wankel engine of course!!
Yeeeeaaahhhh....what a Start and still in one piece! Great flying....quick Captain Blaze, quick.... You made my Day!😎🤘
This time it was really crazy but amazing and perfect fun again. We just love this crazy bird. Cheers my friend.
Whoa !!!!! Great hand toss Blaz ! Great flying Robert ! Cheers and Salute !

Thanks for stopping by my friend. I have used the wings from this bird for my drain pipe jet. But I can use them again on this baby for second flight.
You guys are totally awesome, I almost cried at the first take off!!!!!!
Me too my friend ;-) But it was fun of the week. Cheers, Robert
Lots of entertainment and fun for $140! Nice work Pilot Robert and Capt Blaz *salute*

Thanks my friend for such kind words. It was really crazy and a little scary at the start but at the end one great time and fun again. I love it.
These engines just sound the best oh yeah great video brothers.
I would say the plane liked to climb because of the wing area and the speed it was going.
Thanks my friend. Iam really impressed by the power of this engine and only 5cc. Amazing.

Thanks my friend. We will film it again now that we know a little more how to handle it good ;-)
What a Great Video,, Its so good to laugh, with you not at you, really you guys are the Greatest.
I think it's cool that you take time out of your day to tawk to you viewers and I think it's cool that you injoy flying rc planse
I love to talk to our friends here. And thanks for your support too my friend. Cheers, Robert
That was an exciting first take off. Hand tossing her is the way to go. You got skills Robert. Have a great weekend Boyz.
Really crazy my friend. Iam really happy that the bird survived to see another day. Great wekeend to you too.

2 to 4 degrees is usually about right.
this is it with the Wonkle engine, are you ready Cpt Blazzzz
Give it a Toss
We love this Wonkle engine my friend ;-)
Whoo the Wankel is an absolute rocket! Very impressive
Check the elevator and main wing incidence
I will my friend. Thanks.
It is just too much power for the lift the wing produces at the wrong time. You have twice the power level of a "normal" 5cc engine coupled to a high lift platform- it will go nowhere but up.

It was really crazy my friend but so thrilling. And I think also that this bird is not for the quarry flight ;-) Big salute to you from Slovenia and have great weekend.
Have a great weekend to you and Captain Blaz and you families!
You to my friend.
Fast Frankendevil!! Find one of your crashed planes and put on a rudder, that will help it to be even more Frankie boy. Great to see you fellas. I think Blaz isn't really disappointed that he does not get engine. look forward to next time.
It really is my friend. And rudder would be good here for more control. Cant wait to fly it again. Cheers, Robert
Hahaha, fantastic! Now this was a true adventure, loved it.
Thanks my friend. It really was and I love it.
You pair are bonkers lol great job big salute to you Boath 👌🇬🇧
That was sick lads the motor was crazy got to get 1 nice flight robbo mate🤙🤙🤙

9x6 is the sweet spot for this engine.
David McIntire - I agree, if it is light enough. It does need a rudder. Fly it high, run it out of fuel and perform dead stick aerobatics to the ground. Good fun flying.
Too much power on takeoff. Get rid of the landing gear.
Maybe yes, maybe no. Rudder is nice but not an absolute necessity. It is a lot easier to be a humble pilot and change yourself to fit the airplane and the way it is designed and it's flying character than it is to change the airplane to fit you.
Very enjoyable video. Interesting plane and a great crash. I'M glad your brother didn't die.

Its really great my friend and Blaž was lucky this time. Still he was away and it wasnt so close.
He probably is too!
WOW WOW WOW WOW SHIT!!!!! Thank God none of the family was setting at the picnic table. :-( LOL :-)
This was really crazy this time. Iam really lucky that the bird survived to see another day. At the end it was great experience all over again. I love it. Cheers my friend.
That was perfectly awesome my friends!
Luckily the family was not sitting at the bench! 😲
Anyway, great flight and perfect deadstick landing! 👍

Can not rush Captain Robert we love to hear him babble.
LMAO! One of your best videos!!! Boy that engine really smokes! Doesnt sound like I thought it would at all...
It was really crazy my friend and so much fun this time. I just love these kind of filming when you dont know what will happen. Perfect. And the engine is really amazing.
Congratulations Captain Robert and Captain Blaz!! We have all had those, “Oh s##t!” moments! 🤣
Thanks my friend. Still at the end it was great fun filming this perfect baby.
"I ALMOST DIED ON THIS VIDEO"--Blaz you're sooooo funny!!!!Dramatic video guy's----FAST AIRPLANE!!!!!!NEEDS A RUDDER!!!!!
It was really crazy my friend but ultimate fun. Cheers
good flying Robert great sound.
Thanks my friend. Next time we will be quiet so we can hear it good.
Maybe add a little down thrust in the motor?
Maybe. Or smaller prop.
You guys are great.....love your channel.
Thanks my friend for kind words and for all support.
Another great video. What was that white thing in the sky behind you guys. Looks weird in the video.
Thanks my friend. I must check that in the back. Cheers, Robert
Yous two are funny as and I love it from Australia
Fast run to the Camera , fast flight and good sound off the wankel Engine 😎✈️👍
Walter Luder yes i run as fast ad i can ;))))
Thats so crazy.remember your flying a glider lol but that was awsome flying like always .what a cool sound .love it
It really was my friend. But we had such a good time filming this baby. Perfect.
It is a well built plane! WooHoo. We have had many take off's like that and have hit each other many times! HaHaHaHaa. Now you will set the perfect expo. Great flying and video from the Petrincic Brothers! HaHaHaHaa. Ricky.

That wire will always act like a trip wire grabbing the the grass flipping the plane on landings in the grass
Thanks my friend. It was crazy but amazing. I love it.
Wow! That glider is built like a brick outhouse!
Not surprised you had to hand toss it to get it off.
(The ground. I mean the ground).
Good one my friend ;-) Still we love good hand toss from time to time. Of the planes ofcourse ;-) Big salute to you from Slovenia.
The CG is always between 25% and 33% from the leading edge of any straight wing airplane and it's usually right at the thickest part of the wing (which is usually at the main wing spar).
With a wing like this one where it is wider at the fuselage than it is at the ends, just use the thickest part of the wing to set the CG.
You can also check it together by having Blaz put his finger under the thickest part of the wing tip, then you do the same at the other end of the wing. I promise, it works everytime! I have been flying models and full scale airplanes since 1987.
BTW, It is different for swept wings and for biplanes. For swept wing and biplanes it requires some complex math and geometry.
Also, this is basically a glider, yes it flies fast but it will also fly very slow, notice how long it floated on the approach to land without the engine running.
You could easily use half or less throttle and it would still fly great because the wing loading is very low (ounces per square foot of wing area).
At a slower airspeed, the controls would be much less sensitive as well.
This plane was meant to still be a glider. It has a small tank for fuel so you get up high in the air, then when the fuel runs out, you can glide for a while with no power.
If you add more weight by adding more fuel then it will be too heavy to use as a glider.
If you only want to use it as a powered airplane then by all means add the rudder and more fuel.
Of course I would probably try to figure out a way to add a rudder but that would add to the weight and wing loading.
Also, you can't always use the amount of elevator trim to determine CG because the angle of incidence of the elevator may not be correct, those cheap Dynam airplanes are bad for not using the correct angle of incidence and many times their control surfaces are warped!!!
Good purchase :-)
All the best :-)
Thanks for great informations my friend. I was trying CG at 33% from the front and it felt so nose heavy but once in the air it was just crazy nose light. Still it was great experience and I didnt want to glide much becouse previous owner said that it needs speed to fly good. But like you said it glided really good when the engine died at the end so maybe next time I will try to take the bird high and the reduce throttle and glide down. And maybe we can fins some bigger fuel tank that will fit inside. At the end I can say that I have really enjoyed this flight and filming. And maybe I will put this engine on Fokker plane instead of that Magnum. Big salute to you from Slovenia, Robert
How do you determine whether it is nose heavy or tail heavy? What method? Please?
And.....what percent of throttle do you use to set the elevator trim for level flight?
I always set CG from the manual and then I see how the bird flies at arround 65% of throttle. At that throttle it should fly in a straight line not up and not down. And then you see how much you must trim elevator and in which dirrection. But its always easier to fix CG if I have nose heavy bird and more easy to control the plane on maiden flight.
That is a very good way to do it my friend, that is the same way I set the CG for maiden flights, I always use 60 to 65% throttle to trim for level flight but I never use the elevator position or the trim position as a guide for the best CG position.
I always use flight characteristics as the guide for best CG position. The final adjustment of CG depends on my own flying style (as long as it is within safe limits).
Slightly nose heavy will insure that the bird is more stable on takeoffs and landings, and especially landings since a forward CG helps to prevent ballooning on approach to land and it helps to keep your bird from bouncing once it touches down on the runway.
But, it is very important to make sure it isn't "TOO" nose heavy, otherwise the elevator will not be as effective at raising the nose and will likely tip over almost every time on landing, especially in grass.
I have found that some manufacturers like Dynam are giving wrong CG positions in their instruction manuals (not really surprising, eh?)
I will try to find a way to demonstrate flight characteristics of a plane that is too nose heavy as well as one that is too tail heavy so your viewers can have a better understanding of what is "TOO” nose or tail heavy and what it should look like when the CG is good.
I'm not an expert on the matter here but still feel the need to clarify a bit.
The CG can be absolutely anywhere and simply depends on how the weight is distributed. Should it be anywhere? No, at least if you want your plane to be both controllable and stable at low speeds. Put it too fore and you don't have enough elevator authority to fly slow. Put it too aft and the airplane becomes (longitudinally) unstable in slow flight. So for each plane there's a range where your CG should be unless you're crazy.
Now, a simple analysis reveals that if the CG is at or fore of what's known as the aerodynamic center (AC), the plane is longitudinally stable at all speeds. Which is nice. And for practical considerations the AC can be assumed to be at 25% chord. So put your CG at 25% chord or fore of that then the plane is stable at all speeds. But put it too much fore of 25% then your nice and now very very stable aircraft will run out of elevator authority when you try to fly slow (and make a nice landing). Of course you can modify your horizontal stabilizer / elevator to compensate but that will add drag (because the horizontal stabilizer is working against the lift generated by the wing). Put it aft of 25% and the plane becomes more sensitive to elevator, which may be nice, but also means there's now an airspeed below which the airplane becomes unstable. Too much aft and that limit occurs already around or above stall speed and may result in loss of control (and stall, making things worse) if you ever fly that slow (as you probably are when taking off or landing).
So you'll probably want your CG to be somewhere near the AC for a nice balance between elevator authority and low speed stability. And for practical purposes that means putting the CG somewhere near 25% chord because the AC is not far from that. (If it actually exists. Which it really doesn't for real wings but that's not important now.) You can put it fore or aft but not too much. I guess that's where your 25% comes from. I have no idea where your 33% comes from though. For real airplanes 33% sounds a bit too far aft for comfort and may start to risk the stability in slow flight depending on the plane. I guess it doesn't matter quite as much for RC pilots because most RC planes aren't really ever flown critically slow. (Mine are, check my channel for a truckload of boring wingcam videos.)
And if the wing is not a straight rectangular one but tapered/swept/delta? Which one of the infinitely many different chords to use? The answer: the mean aerodynamic chord (MAC).
No rudder on a tail dragged, what could go wrong? Salute!
Entertaining video...lots of drama and action :) Enjoyed watching it, as always :) oh yeah
It was really crazy my friend but so much fun. We just love to test and film planes so much.
If it doesn't smoke, it's broke...
Very good my friend. I just love to see the smoke in the sky behind the bird. It looks amazing.
HEY WHAT WAS THIS HEY. HEY. THAT BABY IS ONE TOUGH PLANE. HEY. THAT WANKLE SOUNDS AWESOME. NICE JOB ROBERT THE SECOND ATTEMPT WAS JUST PERRRRRFECT. AND A NICE DEAD STICK LANDING. HEY. THIS IS WHAT IT'S ALL ABOUT. THIS IS REALITY TV AT ITS BEST. THANKS GUYS
Thanks my friend for stopping by. This filming was crazy but awesome. Oh yeah.
Congrats on the maiden that big bird can sure take a beating!
Thanks my friend. This bird is really great.
Oh yeah rotory engines are crazy! Nice crash and flight, sounds good too
It was really great experience and so thrilling to the end. I love it my friend.
hi robert. i saw your black color starter. what a brans is it? what battery need for it. thanks.
I think it is robbe and I have 12 Volt baterrie in my start box. But it can also work on 3S baterrie. Cheers my friend.
I love you guys so cool to see your Channel old video new video doesn't matter
OMG ! you nearly hit the car pilot Robert eh! salute from the Philippines! oh yeah...
A mini wankel rc engine? I have never seen one. amazing, nice sounding engine. Ouch. In the air, nice crisp running motor. cool bird!
HO HO du bist nich Capten Blash du bist Capten Crasch. Ich liebe deine videos, darum dspas ich weis nie wie hat das beendet mit dem MODELL. Troz dem du bist Grosse Kampfer ,Capten Crash du must weiter kempfen. Mfg Miloš
You guys are hilarious!! Congrats getting it in the air!
Thanks my friend. We had such a great time filming and preparing this crazy bird. I love it.
You guys always hilarious and fun, hahah..
No rudder with a glider wing...what could go wrong?
Great video! I'm glad it's still in one piece and will fly another day :)
Thanks Wes, me too ;-) Cheers my friend, Robert
These were the good ole days
Im pretty surprise that this plane flew so well. Waiting to get this 1600mm Spitfire ,but hearing the sound of this gas model makes me want to change my mind.
Me to my friend. Some more settings and it will be perfect flyer. Still Iam also dreaming to have FlightLine Spit someday. Its really amazing.
@@PetrincicBrosRC a rep told me that they will be back in stock in October, and in November they will have some sale on all products so you can try and source one then.
Excellent, you are fantastic 😄👍
I love you guys!!! Wish I could meet you someday!!!!
Good job boys, you 2 should be on the stage, but it would have to be a very big stage to fly around,, funny men,,
I apologize for just watching this video, I missed it somehow... the wenkel/rotary engine is great! From my understanding of the wenkel the displacement is actually in the power class of engines twice its displacement.. 1.3cc is close to 2.6cc in piston engines... The Mazda engine here in the US are like this.. The wenkel loves high rpm!!!
I think it's flying a bit fast for the wing,
i'm wondering what glider did it come off?
Oh it was really fast like hell my friend. And I was flying with max 60% throttle. Still it was great.
