the screw on my throttle servo keeps coming loose so it slips on the head of the servo this is bloudy anoying as if i put the brakes on full it will slip all the way around so when i let go of the brakes it will open the throttle all the way till i do the oposite and put full throttle
sorry if you dont understand its hard to explain[]
i can tighten it after and it is ok but i dont want to be racing and all of a suden i do this and i go crashing out.
any one got any suggestion to keep the screw from coming loose? washer ect?

Are you sure the splines on the servo or horn are not stripped?

i had the same problem w/ my steering horn....the splines were not stripped, but they were the wrong ones for the servo.

it was a real pain.
