Default Servo keeps going out?

Servo keeps going out? I have a trex 450 and I had a bad crash and now I keep burning out Aileron servos, I have tried two now one was a new 65mg the other was a 65hb, Can anybody till me why the same servo keeps going out? I have a servo tester and before I put in heil they work great and in the heli they work for five minutes and twitch a little and then quite working.
Can this be the ESC or Rx?

In all probability the crash also effected control linkage which is either jamming or not permitting the servo to travel the full distance as demanded by the TX. (same hole on servo arm used? and was servo positioned with trim set at neutral on the TX before the arm was re-attached to servo?
Any servo, especially digital irrespective of model or brand, asked to hold a position it can not achieve, caused by excessive EPA or binding linkages etc will experience heat build-up and could fail within moments.

I dont see any binding at all, and end points are all at 100, It worked fine the hole time I was setting up the swash. I will have to wait until I can get some more servos.

When they die, is it in the air?

I ask because you say you setup the swash and everything works fine. That must take some time. But then you say that they die in 5 minutes---but is that while flying, or also on the ground? Perhaps something in the head is binding with the rotor spinning, which might overwork the servo.

Make sure the servo itself the plastic case is not being pinched or twisted
