i picked up an old turmoil flatout that was in good shape except where the aileron servo mounts .i was looking and made a mount out of balsa for 2 servos.what are flaperons for and what is the plane capable of doing with them?downsides?what are they good for?
i have a dx7 so flaperon mix and such are no problem

oly - rcer:

I recall flaperons being used first in U control stunt aircraft. Basically they allowed the airplane to turn a tighter inside or outside loop in addition to abrupt manuvers. When the elevator goes up pushing the tail down on the CG axis, the flaps go down pushing up on the axis. The flaperons can be used for the same basic principals for 3D or pylon racing if the pilot is willing to carry the additional weight of another servo for the wing. You may also use the flaperon system as simple landing flaps with a little more programming. ENJOY

The flaperons can also be mixed to go up when the elevator goes up, making high alpha manuevers a little easier by reducing it's tendency to tip stall. Be forewarned, this will also decrease the amount of lift your wing generates, so if you try this, mix sparingly. If you're using Real-Flight 3.0 or greater, the E3D has flap mixing so you can see how you like it.

thx didnt realise i had it in my rf shows ya how much i've been thru it lol anyhow tried it and sure makes the plane do some strange things.well i got the plane for 10.00 so it's a good place to learn flap mixing.when i wreck it i'll know if i want another or not

Well, I haven't seen any use for flaperons on the turmoil I had. It was about 13oz, even so I didn't need flaperons. They can come in handy for slowing a plane down during your final landing approach. I use them on my Acro Master, because the landings are at least 35mph, and it takes around 200ft. to finally slow down. With flaperons, that stopping distance is reduced to about 30-40 ft.
