hi, i put a fairly used 645mg in my ultra comp yesterday, i used the same servo in my maxx and then in my revo, and now my buggy. but the thing is , it performed like it was new after 15 minutes of rolling around in the street (i was on the 3rd tank of the break-in, so no eratic driving) and then all of of sudden for about 10 seconds it starting glitching like a mad man and then i lost control of the steering servo. so now everytime i time i turn the tx/rx on the servo turns the wheels left and and torques theit down to the point where it looks like the turnbuckle is gonna snap from the stress.

so anyone have an idea of what could be wrong? it never had any acces to water or anything
