I was wondering if i can use JR standard 537 bb servos on the ailerons. 48oz of torque on 6V. I will be attempting to do 3D with this plane. Info would be great.

I am running Futaba 3004. No problems.

I am running standard airtronics with no problem.

Thanks for the info. Now, what would i use for elevator and rudder?

Smokey

Futaba 9204 on both.

i am running the following:

wings JR 531
elevator JR 8103 90 oz
rudder JR 8411

Are you using 2 servos on the elevator?

Smokey

I am using the standard pull pull on both rudder and elevator. i did mount a 1/4 square higher on the rudder servo so that the 2 servos would not interfer with each other. With this one servo the plane has good elevator power to hold harriers and elevators. Mine are mounted in the location DP recomends. If the cable every breaks the plane will be toast, i have read were some flyers are using the hitec 225 bb sevro as it very small and strong, and under 30.00 each. I can't speak on them personally for the elevator each 1/2 having its own servo..........

I am using FMA on the rudder and the elevator with pull-pull
on both. The servos are metal geared, coreless, around 80
torque oz., and the transition time is .010. Works like a charm.
