Got a new Solar D770 for my Rustler and it is too fast for the truck. Anyway of slowing it down? My stock radio does not have exponential. If I upgrade my radio, would adjusting the steering exponential slow down the servo? Thanks.

Most middle to high end tx have settings and option that allows you to tone down the servo speed. I know the MT-4 has this feature and cost about $250

EXP does not necessarily slows down the speed. Instead it just expand or limit its aggressiveness.


EDIT: if your on a budget, you can pick up the flysky gt3b for under $50 and has a ton of features.

Does your radio have a Duel Rate? You can turn that down and see if it helps.

i had this problem with a JR9100s when i first got it, now i cannot drive anything too much slower than that adjusted to it pretty quickly
