ive got a revo 3.3. the problem im having is I keep burning up my throttle/brake servos. ive replaced it 3 times now and just lost another one yesterday. it just seems to loose all electrical control. I tested the radio by installing other servos and they work fine. ive lost a traxxas servo, a couple lhs servos and the latest was a savox servo. they work fine for a while but then just instantly stop working. I was just wondering if anyone else has had or is having this problem? and any suggestions for resolving the problem would be greatly appreciated. thank you in advance.
