since I posted here a while ago I did buy one. it is actually working well. the problem was that the servo head that I was using was a bit worn. So, I put a piece of tissue in there to tighten it and add some friction on the front one.
then on the back I just put a tight servo saver and now there are never any problems.
before the car would hit something and then the servo would be so out of whack that I would have to stop racing. that really sucked.
untill next time.
