- I did a video to show how I CG my planes, also a little trick to stop the tail rudder from ever coming off in flight. Hope this helps someone, and if there is somthing wrong with what Im recommending, please point it out. Thanks to all viewers, and special thanks to subscribers!!! Correction to the video, You need to measure from the root of the wing, not the wing tip, sorry I missed that!! The second dot is the correct CG spot!! Thank you ru wingout for pointing that out : )
I did make a mistake, the measurement is from the wing root, not the wing tip, Thank you ru wingot for pointing that out.
Just received my E-flite Extra 300 and like your techniques for CG and tail pin. Will be putting 3.25" mains and 1.5 tail wheel on mine - kind of bush plane looking for my long grass runway (front pasture). It's all good - I'm new to YT (old person) and not up to speed on the posting/commenting process.
@@ruwignout9859 Thanks!!! I had a tail rudder come lose before, but never again lol🤣 That's awesome, I hope those wheels do the trick👍👍 All good , thanks for catching that in my video, you always got a friend here👍👍👍 If there is anything you need help with, let me know. If I don't know, then we have a big group of RC Pilots on YT, and one of us should be able to help you😎
The instruction book that comes with this plane says to use a 4s 3300 that weights about 13oz.. so I bought one of the exact batteries. but I'm having trouble and worried where the proper CG is, and I haven't found a video with anyone using the exact recommended 13oz battery.. the 2200 venom youre using is only abt 7oz... which is why you have to push it all the way back? so my question is... since I have the exact/recommended battery should the CG be perfect without adding or reducing weight?
Steve Short My manual recommend the 2200 mah battery, wtf is up with that lol!!! But, in any case, if the battery you are using has no space to move forward or back to adjust the center of gravity, the only thing you can do is add weight to get it the way you want it😕. I like the smaller battery anyway, because you can have more fun with less weight!! 🙂🙃🙂. To answer your question though, yes it should be perfect using the recommended battery, but rarely ever is, and really hard to figure out, when you have two people with the same plane, with two different recommend batteries lol!!!
BALAZSER1 you should probably remove this video and post up one with proper info. Many people don’t read comments and your method leaves the plane very tail heavy.
Not that someone who doesn’t know how to balance a plane should be flying it anyways.
I'm glad you didn't take down the video. Some airplanes want you to measure the CG at the tip. This is a good method for doing just that. Thanks
This is so funny. I thought I measured my CG wrong because I did measure from the root and not the tip. The reason it's funny, is because I had my battery was all the way forward and it still seemed like it needed nose weight. But my friend has the same plane and I saw him put his battery in and he put it back in the compartment. So I tried it, and my plane flies a lot better with the battery back.
Nice info! For your rudder, you can also use some tape or vinyl. Doing this will not only be second security, it will also seal the hinge to lessen drag by preventing air from going thru.
The CG is a fixed point on the aircraft regardless of the battery used. You move the battery to obtain the correct CG. You need to take this off of utube.
That's right . you move the weight around , not the CoG . Especially in these small extra type aircraft .
Couldn't agree more. Massive misinformation here. CoG is NOT an arbitrary location based on a battery. It's a fixed point generally based on about the first 1/3 of wing chord.
Awesome tips and the CG is the main thing for good flying. Thanks for sharing my friend!
Lorenzo Jalbert Thanks!!! The weather sucks right now, it's been bad a few days now, waiting to fly always sucks😭😭😭
Lovely informative video here all the way my bro!
Thanks!! I did make one mistake though, but I pinned the comment, and put my error in the description lol🙉 Thank you for watching, you are awesome, and greatly appreciated🙂✌👊
The measurement of the CG is to be taken at the leading edge from the Root of the wing that is where the wing meets the fuselage. the wings swing back slightly gong out to the tips causing your 1st mark to be wrong. but your second mark looks to be in the correct place..
Todd Ullmann Thanks👍 Yeah someone else pointed that out shortly after I posted the video. I quickly made a correction in the description of the video🙂. Thanks for watching, and for commenting👍👍
Excellent tips! And yes you did it correctly! Now add a little tail weight and enjoy the 3D flying.
Thanks for the comment !!! Also, thanks for the weight idea, your right, I do need to add some wight to make it absolutely perfect, thanks!!!
@@BALAZSER1 , doesn't take much weight to make a huge difference. I added a half Oz at a time till I fond the sweet spot.
Awesome!! Will do!! My aileron servo gears are kind of rough, feel's like they don't mesh perfectly, are your's like that ?
@@BALAZSER1 , mine feel pretty good actually. But I am used to their mg servos feeling like that.
@@theflyinggreek6329 Cool, I won't worry about it then. They will probably smooth out with use. Thanks!!
My manual says to balance plane inverted
Yeah, mine does too, but you can do it either way!! A little off is ok, way off is a bad day....
Great tips and tricks, on a low wing you want to balance it inverted, but what about a mid Wing like this 3D plane does it matter if its upright or inverted when balancing for CG?
Also I've been flying the E-flite Timber X for quite a long time now, do you think this would make a great second 3D type aircraft?
Thank you sir.
Rob
Thanks, happy to help!! I check this plane right side up, it's easier for me to get the CG the way I want it, depending on the way I'm going to fly it : ) I don't have a Timber X, but that is a amazing airplane, congrats, I bet it is a blast to fly!!! The Extra would without a doubt be a excellent 2nd 3D airplane, it is a great flying plane, with more than enough power!!! Thank you as well sir.
@@BALAZSER1 awesome thanks, yeah same here i balance everything upright cuz it's easier. The timber X is a plane I think everybody should have in their hanger it's crazy lol.
But damn you convinced me, I just put an order in for this beast I'm excited now :) subscribed!
Yup!! I want the Timber, but I have like 15 planes, and no more room lol!! My hobby, has outgrown my hanger space lol!!! Awesome bro, you won't regret it, the Extra has loads of power, it's OP!!! Subscribed to you was well!! 👍👊
@@BALAZSER1 seeing how excited you are in the other videos of the extra I was like damn I have to own one lol.
Yeah you're Hangar is pretty full there you probably have more planes since this video. You're going to have to add an extension to your hangar Haha!
You will love it!! The plane is way more capable than my current skills lol😂. I did a video of the assembly, not sped up, actual time it took me to build it, 30 minutes lol!! It's a long video, so I don't expect anyone to actually watch it all lol, but if you need, you can skim through to anywhere you have a issue putting it together👍. I need a hanger, for my hanger lol!!!
What!? You don't move the cg mark depending on battery.
You adjust weight, depending on cg mark.
Yeah, I know now, I pinned a comment saying that I was wrong, but nobody ever reads anymore lol 😆
@@BALAZSER1 I read that, I'm just saying cg point is always the cg point, it never moves, I gathered you figured this out but commented it for anyone who may be confused about that specific part
@@kl0udykl0ud55 Thank's, and you're right.....
Have you already checked is motor mounting bracket made of plastic and colored or made from steel, please ?
Elevator hinges are some kind of foam or plastic, please ?
Thank you for review.
Motor housing is plastic, X mount is metal, and the hinges are all plastic!!!
good idea thank you
Your welcome!! Thanks for watching!!!
What do you think about to adding side force generator ?
Side force generators are great, you could totally add some to it, but I don't know if I will🤔. Thank you for watching, and your comment, you are greatly appreciated!!!
I’ll buy that Parkzone F-27 Stryker from you!
I have my 4s 2200 , pushed up close to the front, seems to still want to climb, like she's tail heavy, I like low pass flying, any solution to my problem, thanks for the video enjoy watching it
Scotty Norris You just have to trim that out... hope that helps👍
@@BALAZSER1 I guess so, 2 time in the air, maiden was almost a disaster, during the build I took the control horn off the servo and obviously didn't put it back on correctly, took a hard landing, broke the prop, worked out the bugs and flys great, I could stand a little down elevator, tomorrow I'll make a trim adjustment, possibly 30% expo, just got to feel it out a bit she's a new bird for me
Scotty Norris Anytime you have damage, you have to adjust the trim, been there, and will probably be there again lol!! I don’t even mess with the expo, it’s at stock settings, I just trim it to fly straight, and call it good lol!
@@BALAZSER1 what happened with the build, I took the horn off the rudder servo, to secure the elevator screws, evidently I didn't put it back on right, I saved my plane and I'm happy about that! I'll have more flying time tomorrow and get it dialed in ,start off with my Timber X for a little warm up, I appreciate it man! Always need advice in the Hobby never ending journey, always learning
Also after watching this video I went and pinned every rudder that has CA hinges! 😂🤣
Happened on my FMS 1700mm Super Cub, the foam hing broke so I put CA hinges. I had it on floats I grabbed the rudder to pull it on the dock well I ended up with just a Rudder in my hand and the plane floating away because I had disconnected the battery, So I had to go swimming with the fishes! 😬😁 lol
Awesome!!! The day my Yak54 rudder was flapping in the wind, was pretty scary lol, and ever since then, I put a pin in LOL!!! I would have been laughing so hard at myself, standing there, with my rudder in my hand, wile my Super Cub was floating away lol!! I have had to rescue my Maule M7 before, but luckily I have a inflatable kayak on standby, just for that lol!!! : )
@@BALAZSER1 yeah I could have imagined I was already scared that it came off in my hand let alone in the air like it happened to you, I would have needed an extra pair of underwear if that happened to me. lol
The maule is an awesome Bush plane, I got mine a part right now because I'm putting pan and tilt camera inside the cockpit for my fpv head tracker can't wait to fly it fpv!
As for laughing there were plenty of people there laughing when I had the rudder in my hand and the Super Cub floating away, it was a fpv float fly meetup, I turned so red in the face! Haha 😁
@@BALAZSER1 I think I'm going to need a an inflatable kayak good idea thank you again! Lol
Yeah, It beats stripping down, and dragging a plane back to shore in your underwear lol!!! Been there lol!!! YW : )
@@BALAZSER1 omg I know right? It totally hilarious when you have an audience and no choice, lol
Hitting Bass Pro Shops tomorrow to get me one 😁
I glued my rudder a lil less than a half inch to high ...what should I do please help
Oh no!! Sorry it took me so long to see your comment.... I hope you fixed it!!
How did you fix it
A quality BNF or PNP model will fly ok straight out of the box without any balance measuring. Any C of G fine tuning needs to be done by flying it, not with tape and string. BTW,,,,,,,,I do have one of these models. It flies amazing. I have many BNF and PNP models. None of them were ever checked for balance before the test flight. All were within flyable limits and all were fine tuned for C of G by the way that they flew.
You sound similar to mike lindell. :)
You may want to re-read the manual, because your measuring the CG completely wrong. The CG range is measured from the wing leading edge at the root against the fuselage. Of course your CG is way off you are inches behind the CG range and you are outside of the stability margin. Always balance to the measurement never change the measurement to where it wants to balance.
Not to be repetitive, but the manual says wing ROOT! So, even though you seem like smart guy and experienced, have to discount what you've said. I'll measure mine at root, not tip.
jalbert222 If you read the pined comment, you will see I stated I made a mistake about that... Hope you are enjoying flying your 300👍
@@BALAZSER1 Hi. Put the plane together and went out two days ago for the maiden. I am an intermediate pilot with 25 years experience. Finally the the plane tweaked. The plane is well made, but terribly documented and some bad engineering. None of the servos, at their recommend 'last hole' of the servo arm, will center properly when flying. And the 45 and 50mm low rate travels are ridiculous! And the CG, with the right battery even fully forward, required 3 ounces weight in the nose. Flies well, but..........not impressed with engineering.
🛫🛫🛫🛫🛫🛫🛫 🤙✨
Thanks!! : )
He cares more about 11k views than he does about misleading people. Like others pointing out, measure from wing root not tip and cg is always the same place no matter what battery you use. You should pull this vid down my guy, it's A popular plane and probably messing lot of folks up..
I don't care about veiws on youtube, I don't make money, nor did I ever plan to make money on youtube.... If people would read anymore, you would see my pinned comment saying I made that mistake, and explained that...
If anyone follows this advice you WILL CRASH YOUR PLANE! This is the WRONG CG measurement and this video needs to be taken down! Good attempt so a redo making this vid will do you well.
If you read the description of the video, you'll see I corrected that, but, thanks for watching 👀
I also pinned a comment pointing out my mistake, that it's the wing root, not the tip, thanks 👍
@@BALAZSER1 streaming on tv and other sources as I do doesn’t show comments or descriptions. And most folks watch vids without reading.
@@kmatch1 and yet you are still able to comment?…
@@waynemiller6070 Trying to save someone from crashing a plane was worth a minute to switch devices. Interesting how this bothered you 2 years later.
