A guy in our club has one and he uses futaba 3004 standard servos and powers it with a super tigre G90. He's only been flying for about 45 years so what would he know about anything? lol

I'm sure others will tell you to go with the digital high torque....you know, the ones that run your batteries down a lot faster.

I'd go with the 3004's personally and use a 6v receiver battery that will up the torque from 42 ozs. using a 4.8 battery to 57 ozs. using a 6v.

Thats plenty for that plane.

good luck
