Ok first let me say I'm running a mamba max pro with a castle 3800 4 pole motor an a savox 1230sg 500oz on Dx3s.ok my problem is when I turn the steering wheel back and forth my truck will start to go forward by itself without me hitting the throttle.
I had this problem a few years ago and its driving me crazy cause I can't remeber what I did to solve it and what the problem was.
So any help would be appreciated.
Thanks
Josh

Castle ESC's have a notoriously weak BEC and the servo is drawing more current than the ESC can supply. Some radios like Traxxas and Spektrum are very sensitive to these voltage drops and glitches occur. The solution is either a glitchbuster cap (Spektrum or Novak sell them) which plugs into a spare receiver or an external BEC that bypasses the ESC for receiver power directly (funnily enough most people buy Castle BEC's to fix a Castle ESC problem!)

Either that or a servo that draws less power (Savox are amp hungry) or an ESC with a stronger BEC (Hobbywing SC8WP) will fix it.

Yeah I was thinking that.I got the servo,esc,and motor used and today was the first day I tried all of them together so I didn't know if one of them was screwed up or what.Then I remembered having this problem awhile ago and couldn't remeber what I did to fix it.But now after your advice I remeber I used a glitch buster and it fixed it.So I will try that tomorrow and if not then ill throw my rx8 in even though its over kill for the truck I'm running.
Thanks for your response and help.
