I have a Trex 450 plus. Since a recent crash I have had problems with my tail servo. After about 3 mins flight time the tail servo blowes. This has happened twice today. I have a servo tester and both are not working. Tail servo is an Align digital DS 425M and gyro is an Align GP 790. Any ideas you good people out there. Thanks

couple of things... firstly try the servo see if it moves smoothly if it does then probably not a servo related problem. It sounds more like a problem gyro.. basicly because it works initially then fails a bad servo would most likely fail straight away the gyro could be a thermal issue after you apply power something gets a little warm and stops making contact... put a quark on it they are brilliant... and reasonably priced...Steve...

I used a Spartan quark clear case gyro with a Futaba S9257 on one of my 450 tails, I never had a problem with it, the tail was solid. Since i have modded my 450 to FBL i could sell the Quark gyro (used), also i have an Align DS450 servo i dont need (used), i could sell too.
