    Application(s): Sail Plane Alpina, Tangentmodel

    Comments: Works fine since more then 105 hours in flight.
    All Ruders still center well. Strong enought even by flying fast ( 120-160 k/hour).

    Application(s): Cyclic servos on EXI 500 helicopter

    Comments: Excellent servos, fantastic resolution and centering. I run them at 6v to get the speed up (torque is more than enough)and they perform very well. 9650's are known to be very reliable, so I trust them in a heli. Zero failures to date. I was going to use MG 930 servos in the heli, but read of a few problems with those. Sticking with Futaba!
