July 11, 2013Application(s): Elevator and Ailerons on a 50cc Yak 54
Comments: Powerful servo with a good response time for a fantastic price. I've had these on the elevators and ailerons of my 50cc Aeroworks Yak flying imac and light 3D for about a year now with ZERO problems. They have performed fantastically- I'm about to buy more for a 50cc Extra.

Comments: Use it with JR 40Mhz transmitter. Servo jittered. Changed the transmitter from PPM to PCM. Jitters gone, centers 100%. No problems and using for 3 years now.

June 15, 2010Application(s): 30cc Gas airplane.
Comments: These servos are pretty strong and center pretty well, but they have one major flaw. They twitch and extend to one side when they are powered on without a signal. The new spektrum RX gear doesn't send a signal to the servo until they find the TX so with plugged into my newer AR6200 they all twitch.
On my older firmware AR6200, they don't twitch because the RX sends a centering signal to the servos until it finds the TX.
