ORIGINAL: Leardriver
Oh yes I did loose my first 2.6 Extra when the motor quit (another story) but what Marc didn't tell you is that on the 5th or 6th flight of the the replacement the rudder servos (Hitec 5945s) went hard over 30 degrees and locked solid. Thanks to a very skilled pilot the airplane was saved (really a nice bit of flying) but the rudder servos were locked solid...both of them. Obviously one failed and took out the other in a very short period of time. Oh, and when I set them up I always use an Ohm meter to make sure that they are setup without any binding. Needless to say I am done with Hitec.

What we also don't know for sure is if your servos locked because you had them ganged on your rudder and perhaps they were not programmed 100% correctly. Maybe they were fighting each other and that led to the failure when the servo perhaps overheated. Can you say with 100% certainty that before that flight those servos were dead on at subtrim and end points? Did you put them on a meter before that flight? Did you assume they were perfect from other flights?
