Application(s): 2 Great Planes Edge 540T EP all 4 servos on each plane

Comments: out of 8 servos 3 of them were bad right out of the box. 2 of them never even got install on the first plane. The next 2 servos bought for this plane did work. On the second plane all servos were installed and working. During the pre-flight checklist at the field I found that the right aileron servo had a bad tooth at the middle of the throw. I do not know how long they last but from what I can see so far I am not happy. The 2 planes were built almost a year apart. I would have used a different servo but because Great Planes requires the torque and size of this servo I am stuck.

Application(s): I fly them in a 4 foot span 3D model, electric powered using an AXI 2820/10 achieving 200 Watts per pound!

Comments: Robust and reliable servos that have flown solid for 3 1/2 years. One servo had a pot go bad, but was still working. They are good, but could be a little faster. Excellent value for money.
