a cheapish plane should get an improvement by an accerelometer.
no aileron, just rudder and elevator.

the pre configurated plane mix in betaflight is made for aileron rudder and elevator, can i choose this an just skip ailerons?
would i need to do a costum mix?

even on betaflight wiki i couldnt find a lot.
some sources of informations? videos, links.. thank you

You can fly planes on three channels just fine. Used to do it all the time ,no mixing needed. Keep in mind the rudder will be on the left and elevator on the right. The roll on the right stick just won’t do anything. It just not as acrobatic as you are force banking the wing with the rudder instead of changing the pressure on the wing itself. You can do rolls but it’s more of a barrel roll than a snap roll. It’s also a little slower to turn. Keep a little up elevator in your turn so you don’t loose to much altitude. If you wanted to get fancy you could put the rudder on the aileron channel. Since you are flying drones I would leave the controls with the standard four channel setup as it will get confusing. That was for someone who just plans on using three channels exclusively. Hope this helps, happy flying!

thanks for your answer
"no mixing needed" that helps. seems i just didnt mention well, as there is no mixing needed :-)
i used rudder and elevator a few times without fc, just from the receiver. uuf that hurts xD

It’s not ideal as it truly isn’t how planes fly but it does work. With something as light and small I don’t think its going to make much difference. When you add ailerons you’ll be like what was I thinking with three channels. Yeah helicopters and quads are basically the same controls. It’s going to be hard to loose the  muscle memory movements at first if you’ve been flying quads. It might better to stick the rudder on the aileron output in your case. Then at least it would behave a little more like your used to. The biggest hurdle will be that your used to stopping by pulling back on the pitch to stop. Now if you pull back on the “pitch” which is now the elevator and your going slow the plane will stall and fall out of the air. As a plane creates the lift while moving forward once that stops it’s like a fail safe fall. I’ve crashed many an airplane stalling them out on landings/ takeoffs when the forward speed got to slow. Being a little foamy it’s probable not going to damage to much as it so light weight.

i flew it a few times, elevator is was used on roll.

ailerons would be nice but there is still alot weight and no spare room, cant add additional two servos.

wingspan is about 300mm wingspan, it was about 30g? its about 60g? now it will bw 80g uaw

Yeah I can imagine that it would be real confusing not having them on the same stick. It would be pretty hard to install ailerons on something that wasn’t already designed to have them but not impossible. Can you do it with one servo in the middle. You don’t need two servos Just a round control horn and some rods. Do you have a picture of it?

as a rtf, usless 27mhz it flew very nice but rclink was useless. front motors was 3d, both directions.
it was 1s and uaw of 30g

actual i am at 60g without battery and fpv gear, battery is 17g... it will be arount 90g, still to heavy, might not get durability out of it : no option to add anithing additional




actual everything is settup, the only missed thing is stabilization what i guess i will need, the reason i added a flightcontroller. its a small plane, it was very okish even in wind befor, but i guess it will give a better performance out of this small wingspan by a stabilization.


-very old eachine 1104 7500kv motor
-hq 65mm
-two cheapish tiny servos
-xm+
-16x16mm f4
-racerstar blheli_32 1-2s 8a single esc

will come:
-unify nano 32
-cam no desicion actual

will be flown with:
turnigy nanotech 2s 300mah v1

That is small, I don’t think ailerons on that would make a huge difference, it’s so light. Planes didn’t use to come with any stabilization. There was a big learning curve for them back in the day. There were no simulators. You hopefully got it in the air and flew as long as you could before it crashed! I’ve never seen a plane with motors in the wing like that. I’m guessing that’s where the FC will help the most.

dont miss that, i removed the frontmotors in the wing
i was very confused about the 4motor design, bought it to find out if it works. it realy worked very well, i couldnt imagine that, specialy as its a small plane.

very sad the issue was just 27mhz radiotransmission, it was an aio=receiver and brushed 4esc.
brushed biderectional xD funny...
it was indistructible at 30g uaw.
very strange this settup with rotors in the wing doesnt exist more?!?
sadly this concept isnt done in a better quality build i like to explore this onetime.


the wing shape does a bit anglemode byitself from the v-shape.



as i have a pretty powerfull motor, i will need to stear against rotation-force, i realy would like to give this work to an fc and get good accrelation :-) it should fly straight and smooth like a quad :-)

If the wing motors were bidirectional, they were probably meant to act a ailerons so the plane could do rolls. Does the left (throttle) stick of the plane's original remote move left and right as well? 





I'm doing a build thread converting these planes to FPV here: Converting a Toy RC Plane to FPV

its more about a quad than about the classic rudders.
back motors does yaw and thrust, front motors does roll and pitch. pretty all maneuvers are possible, it flew like fully loaded with ailerons elevator and rudder, by pitch backwards on landing it was even like flaps :-)

This plane could do pitch as well? I didn't even think of that but if the wing motors are already reversible to do rolls, it could pitch as well. I guess that's why the motors are on the front of the wing.

With only a 27mhz radio, I can see why you wanted to convert it. If it had a 2.4gHz radio, I'd've considered converting it to FPV as is.

If the motors are reversible so it can do rolls, they can be used for pitch as well. I didn't even think of that!

I looked around and the only planes with this configuration have 27mHz radios. If they'd had 2.4gHz radios I'd've considered converting it to FPV as is.
