Servo Failure


I have purchased a number of servos from HobbyKing and had a good run except for one I put in my glider. Its a HXT 5010 standard size servo. I was flying one day and was in a thermal and the glider stopped responding. It went into a gentle spiral dive and came down in some bush, luckily by a road which goes through the bush. So I got it back in one piece. I thought the ESC (electric glider) had failed. But it was actually the rudder servo which had failed. And if you look at the picture, one of the surface mount transistors has got really hot and burned a hole in the servo case!! Goodness knows why; I'm not an electronics expert. Anyway the glider is flying again.
