How To Do 3D - Knife Edge Coupling Issues - Programming Radio
Вставка
- Опубліковано 16 вер 2024
- Welcome to the Supplement How To Video of the How to Do Knife Edges. In this video I am going to show you how to Dial out coupling issues when performing the Knife Edge.
I also go over how to program several different radios, including the Dx6i, Dx7, Dx7s, Dx8, 9303, 9503, and the 11x.
Please Note: This video assumes you have already properly balanced and trimmed your plane. Although I trimmed elevator first due to that being the main questions I received, you should in reality mix rudder to aileron first. This video is intended as a quick solution only, for Knife Edge coupling. Stay Tuned for more videos when we cover a more in depth review on the proper procedures for a fine tuned flying machine!
Thank you for watching another RCRedBaron Video, and thank you to HobbyKing.com for sponsoring this series!

Amazing! You have just demonstrated in 10 minutes the programming I have been trying to figure out for months. Thanks!
Once again excellent videos. I asked fly buddies and searched for this info and even tried to figure this out myself, although i had no idea what mixes were for at the time, now I do. Cheers!!
Wow I just can't get over that Plane it's just so cool. I know I couldn't afford it, or fly it for that matter. Nice flying and good tutorial.
Thanks for posting this video! I recently started doing knife edges and found it very aggravating that the plane kept drifting towards me. As soon as I would try to move the elevator to counter the drift, I would lose my knife edge. Can't wait to implement your tip! Coulpling...didn't even know that there was even a term for this phenomenon!
Awesome explanation thank you Sir. I have the JR 9503 and love it! Your programming is spot on, I’m getting ready to dial in an Extra 300, Yak 54, Decathalon and P47. You should do a follow up video on advanced mixes like aileron differential, elevator to flap, elevator on the down lines etc...thanks again !
Robert, great video thanks man I hope you & Hobbyking will continue with these how to videos as they have been fantastic so far! I look forward to seeing more in the future!
James :o)
Thanks for an easy to understand guide, cant wait to try this out next time we have some decent flying weather!
Great Vid!!! Exactly what I have been wanting to see, Thank you for this series. Its a big help for those of us who are wanting to learn 3D without a mentor. Keep them coming I look forward to more.
Jon
@RCRedBaron No problem at all, I am really glad you decided to produce this series. I have been looking for a series of 3D how to videos for a while. keep em coming, I am eagerly awaiting the next :)
Jon
Outstanding video! You've answered a lot of questions for me. I'm rather new to 3D, and no one else in my flying group is studying it enough to share experiences with. I've known that it was possible using mixes to iron out undesirable tendencies, but wasn't sure how to go about it. Thank you for this video!!!
Excellent video. For the person wondering what ARF this is, its an EG Aircraft MX2 30%.
Excellent!! you made it easy to understand! I just started 3D planes & just recently bought a Dx8, I been wanting to pull off a good Knife edge! now I think I know how to start! Thanks!!!
I may be old school but i learned to fly 3d on an old futaba 4 channel AM radio before they had computer radios. I can still knife edge with some of the best "modern age" 3D pilots out there.
Great video. Explained why (and which) mixes to use. I had always been trying to figure out what should be mixed with what. Thanks !
So simply explained and easy to follow, thank you RCRedBaron.
great video!! now i understand what those functions do and how to set them. KEEP THE VIDS COMMING!!
Thanks for the advice. And to the PC RC police who comment here: This is all for fun. If you think it is cheating, don't do it; if it is pointless, don't do it. We others don't care about your RC plane morality issues. Keep them for your counseling sessions.
@rcFFBloodyMicks : Jon, I appreciate the continued support of my videos and I saw you linked several of these on facebook! Much appreciated my friend!!! ~~Robert.
Great video! I am a newbie with a DX6 and Apprentice. Loving the hobby and sim flying. Building a 39" Yak as I type.
Thanks for the help. Very useful. Nice teaching by the way.
Great information for my DX7. Thank you.
Fantastic video Robert, much appreciate this series! Again, very informative.
super video , saved me trawling through the manual , many thanks
seriously awesome vid. I already new a little. but this helped a lot, especially the different tx programing
thank you.....
CG should have been the starting point before fixing issues with radio. IMO, cheap planes (like HK) needs much more dialing in. Larger BJ Craft and even smaller 3DHS required very little radio programming to fix "hardware" problems.
Thank you so much for the video. You just translated greek to portuguese. That is amazingly easy.
@7jsm7 : It's one of my favorites in my fleet for sure! Thanks for the awesome comment! ~~Robert.
@celm74 : Always a pleasure good sir! LOL. Thanks bud, I appreciate the support on the vids!!! ~~Robert.
@tankshermanator : James, appreciate the great comment and support! ~~Robert.
Thank you thank you thank you, your a savior, lol, I own two DX6i and a DX7 and this helped enormously, well done and well explained :-)
@rgthd007 : My Pleasure man! Thanks for taking the time to leave a comment! ~~Robert.
@SkyFlyerRC : Hey SkyFlyer! Great questions and awesome comment! One of the reasons I made this video was that I was getting a lot of emails on knife edges, right after the HOW TO video of knife edges was posted. I heard the same issues coming up. So for a quick fix, I made this video. There are many other things that need to be addressed in a plane to get proper balance and trim, but at least I could offer some kind of quick, down and dirty coupling fix. thanks again man! ~~Robert.
Thanks so much for the video, very helpful
Great info and video coming from the Tink I like it and it is fun to watch,, Thumbs up form the COOL TMRC LOL LOL ,,,
@mikem1959 : I'm glad to hear it! Always glad to help my fellow rc pilots out there! ~~Robert.
@joehandsome99 : Hey, thanks Eric for stopping in, watching and commenting my friend! I appreciate that! ~~Robert.
Its all in personal choice and feel. Even with mixes or 3 axis gyro, you are still flying the aircraft. Why drive a car without power steering? No since in fighting the controls when you can mix the trouble spot out and enjoy the flight. But, I know a lot of people that prefer to fight the aircraft the whole time. Kinda like Trimming your plane for level flight. I know pilots that refuse to CG or trim the plane. If they are happy, that's all that matters in this hobby. :) ~~Robert.
@aja1216 : Ohhh absolutely!!! LOL!!! Thanks man! Appreciate the continued support! ~~Robert.
@toolbaggers : Don't let go of the reason you got into flying... To enjoy the hobby. Using Expo or mixing out coupling makes the plane fly more true, allowing you to concentrate on flying and doing enjoyable maneuvers. I was asked if Side Force Generators on a plane was cheating... I simply ask, do you enjoy the way the plane flys with them on? If yes, slap them babies on! Have a good time! If anyone says it's cheating, then they havent enjoyed a plane that was finely tuned yet. ~~Robert.
@sajtoscsoda : Since the knife edge pronounces the coupling issues, the mix usually helps correct all the other maneuvers using the rudder. Coupling is an effect caused by numerous items, including balance, control surface deflection issues, blow back etc. While you may not notice the coupling as much during a flat spin, it will still be there. This mix will help with it. If you do find the mix is causing ill effects, you can assign a switch to the mix to turn it on and off. ~~ Robert.
@TinkerManRC : Alright Sir Presidente! LOL! Thanks for stopping in and commenting! The cool TMRC! LOL ~~Robert.
Great video. lots of good info.
Thumbs Up ~ Eric
Will this work on my Cessna??? lol Great video bud!!!!
@photobart1 : Hope it helped bud! Thanks for commenting!! ~~Robert.
@tenrazo215 : There are some cases where it could have an opposing effect. However, if your plane is properly balanced, thrust line is correct, Plane is trimmed out properly, you should find that this mix will be minor. You typically get coupling from several different sources in the plane. Warping somewhere, blowback, thrust lines, and etc By mixing out the coupling, it should correct the other maneuvers you do. But, you can always assign to a switch and turn this mix off. ~~Robert.
personally i really dislike mixing. but i have a few models that i use for competition and it really does help when the f3a models deviate when in knife edge.
@justlostagain : Thanks for stopping by and watching, and especially for taking the time to comment! I appreciate that!!!! ~~Robert.
it is a really good idea to mix the elevator and aileron to the rudder, and it is working grat for the knife edge, but what happens if you want to do for example a flat spint or something? this mix will help or not? may have to do a diffrent mix?
@toolbaggers I consider it continued airplane setup and fine tuning. to make it perform as I want it to. Is trimming an airplane cheating? If you know you need to add a certain amount of elevator to a manuever why not just dial it in....similar to adjusting the trim for forward flight. Just my 2 cents. BTW. Nice video and very good explaination.
never understood this - isnt it bad for normal flying, I get the advantage for knife edge, but if you dont have it on switch but have it on all the time (as people do if I undestand correctly), then the mix is not something you want in other manouvers..
@Iamsam1969 : It's great comments like yours that keep me happy to keep on making them! My hope is to help someone learn this stuff a lot faster than I did. LOL. Thanks again! ~~Robert.
Yes, each side will have it's own coupling issues. ~~Robert.
Thanks but with these mixes would the model not be reacting like that even when you are just flying around generally?
@RCRedBaron i had coupling issues a few years back, but i haven't had an expansive radio to do anything about it...
Where you programed the mix. Under the SW: ON, Change that whatever switch you want to enable or disable the mix. SW means Switch. ON means always ON, Otherwise, change it to a switch available. ~~Robert.
@RCRedBaron : I want to mention also, that this mix is usually the last step in properly dialing in your plane. So this mix should be minor. If it is extreme percentages, then you have bigger issues with the plane. I haven't found any maneuvers yet where this mix has caused issues with them, in fact, it smooths them out.. Im sure someone has or has an argument against it. This is why we set up flight modes, and assignable switches for our different flying styles and maneuvers. ~~Robert.
@rcpro540 : Appreciate the comment!!! ~~Robert.
your video's are very good thank you sir
@toolbaggers : Programming or mixing out the plane is not cheating. Think of it this way: Do you feel guilty or find it cheating that your car has Power steering? Or Anti-Lock Brakes? Is it cheating to have a front end alignment so the car doesnt drift or wear the tires down unevenly? There is still plenty of work load left over after fine tuning your plane to keep you busy enough. Believe me, this is only 1 small step to fine tuning your plane too. Great Question!! Thanks. ~~Robert.
thanks this helps. i've been having a hand full with my sbach lol
Thanks Good Job!!
WOW. thanks, this helps a lot, I was wondering if you leave this mixing while simply flying, or is this a personal prefrance thing ?
or would it be assigning it to a switch ?
thank you
Is it possible for Dx8G1 to enable R-2-A and R-2-E mix on the same switch ?
Thank you, sir.
OK SO my plane is doing the same. it's pulling to the landing gear on a RT to left.
so becasue I programed it out. your saying I need ot do ti to the other side too ?
Also I'm using a futaba radio. thanks for your post and video
Good evening the Elevetor rudder mix is always active or active only for certain manoeuvres?
In the case for what maneuvers?
Thanks, bye
great vid,i fallow your instructions but on position 0 on my right ruder i got negative 9 on position 1 both are on 0 i got movement on 0and 1 it is o,k or i did something ronght.
I appreciate you guys taking the time to make these videos. I'm ex Heli and just learning IMAC. I figured how hard could it be? Turns out to be far harder than I thought. I’m enjoying the new challenge. My Aeroworks actually knife edges pretty straight but I'll spend some time on this tomorrow. Is there a rule of thumbs for degrees of rudder?
I know it is kind of off topic but do anybody know a good place to watch newly released movies online?
@Roland Arjun Flixportal :P
@Moshe Richard Thank you, I went there and it seems like they got a lot of movies there :D Appreciate it !
@Roland Arjun You are welcome :)
I prefer not to use mixes, for main controls at least. Like flying a heli with a 3 axis gyro, i don't see the point if you don't want to fly the plane yourself. Though for competition pilots I understand, everyone else uses mixing, so you would to be competitive.
Thank you very much!!!
awesome ~
!
8:16. How does the plane maintain lift in that position?
Aron Tesfay The Lift is created by the tapered shape of the fuselage when it’s on its side, The fuse itself becomes the airfoil, if very inefficient so speed is the key to create lift.
@@roymills415 Ahh. Makes sense. Thanks for the answer!
I have a dx8. Ones I done the mix what do I do now when I don't want the mix when I want fly normal. To take away the mix
although mixes are a great tool for removing unwanted tendencies,,,,its much better to adjust incedence trhustline axis and cg first,,, the last thing you want to need to do is flip a switch to peform a single manuver,,any experienced aerobatic flyer knows wierd stalls and other issues can happen with mixes and its better to reduce your workload when flying ,,this is why a snap roll switch is a joke..
who makes this plane?
dont get me wrong with my comments ,,some manuvers like elevators or harriers need flaperon,,,,and of course when your not flying an aerobatic miving gear and flap or light switches will allways reduce workload,,but certain issues should be corrected mechanically and saving a mix or flight condition where its really needed
nice bird
@LmarvinM : Appreciate that! ~~Robert.
Well thats why you have two sticks on the radio,,,,,,to FLY IT !!!!!
@rurouni42 : Much appreciated!!! Thank you! ~~Robert.
Hey coukd u send me the dexal layout?
@Betts456 : Thanks man! ~~Robert.
@jbx907 : Much appreciated!!!! ~~Robert.
Completely different with a heli. A heli without a flybar has no stabilization and is very unstable (meaning randomly does strange things) A plane at least has a predicatable set of quirks to it and is another story. If you want to be a better and smoother pilot, I can say forget the mixes. It was like in the early days of helicopters where they were do switched inverted (would switch the controls like right side up) but it was realized that if you wanted to 3D that it was not the way to go.
Now do Futaba
How much does a plane like this cost?
Brand new between $2500 and $3000 depending on the quality of equipment installed. Used price is typically somewhere around half price.
That is actually a lot less than what I would have guessed. Does that include the motor and electronics?
Yes. This is the 50cc version. 89" wing span. I have the larger one too with a 120cc engine and that will cost you close to $4000 to $5000 depending on quality of equipment installed. The basic airframe kits arent too much. Its the engine servos and other items installed that really start costing the bucks.
Very Nice , I'm learning
3:40 its like cheating
this is cheating, is it?
Always an interesting question. Why does anyone think its cheating? Cheating on what? Or who? Race car drivers who make sure their front end alignment is right so it doesnt pull, is that cheating? How about on your own car? Making sure your plane is flying straight and aligned is the right thing to do. Just because you have your plane aligned, balanced and tuned properly doesnt suddenly mean the plane flys itself. It doesnt mean suddenly the pilot is able to perform maneuvers they dont know or practice hours and hours learning. This is just one small step in making sure your plane is set up properly for a pleasant and thrilling flight! Thank you for a great question. --Robert.
How about stability and SAFE modes?
Just use a $100 gryo
About $4000
Mixes and gyros are no fun im sorry. One of the great things about flying are the different 'characteristics' of different aircraft, and the way they feel. Employing mixes like this will make different aircraft all feel the same. pointless.
no it will not. lets say all planes fly perfect with mixes or even without lets say a 30" foamy or a 42" edge or a 72"edge or a 59" aj slick or a 72" extra or a 89" slick 102"slick 126" slick ,ect ect ect.. they all feel different. no matter what. even if they are mixed to fly perfect they all still feel way different... not to be a dick but you must not have flown very many different planes. and obviously I love 3dhs :) there all made by the same company mixed perfect they all fly different
wow! when they invent radios that program evn MORE u won't hav to fly the plane at all. i mean, u can jst stay home and fly sitting on the sofa :) woldn't it B more fun to actually FLY the plane urself? y do adults ruin everything?
