i have been racing for over a year now and i havent had any servo burn out except the RTR servos from when i started. my son ran an RTR scion servo off an cen RTR buggy and he used it for about 6 months before it finally crapped out. if you set the epa right you shouldnt have an problems. we use the 7955 for steering and my son uses a cheap jr for throttle and i use a hitec 645 for throttle. never had a problem with an servo except the two RTR servos we used for steering and we got about 5 or 6 months of use out of them. i have a friend at the track and he has had the hitec 7955 on his steering since they came out with it and has never had a problem with it what so ever.
