<span style="font-family: "Arial","sans-serif"; font-size: 9pt">My advice is DON'T USE in an airplane, vehicles that stay on the ground these may be ok for. I bought these and installed them in a new plane. All seemed ok on preflight checks, after takeoff and trimming the plane I then tried some different positioning of the plane, all went well until I did a hard left bank. The plane went into a deep bank with no chance of recovering it. Upon inspection of the aileron servo's, one had missing gear teeth on the small gear attached to the motor. The other now has a grinding sound when operating. Since I put them in the rudder, elevator, and so on, we check them all and3 out ofthe four lefthad the grinding sound. Inspection of these did not produces any factual findings, at least that we could see, but still made the grinding sound after cleaning and reassemble.
