yeah, I'm going to end up buying one of those nitro engine kill switches, ther about $60 including shipping. No matter what i do with the idle screw and trim it doesn't work. If the trim shuts the engine off so do the breaks. I need brakes. I'll go to the local hobby store and check if they have anyting good. If anyone can tell me if a bumble bee switch thing will work on my redcat controller? I have one channel left and my controler has the on/off switch the two revvers switches and the trims. Thanks for any help.
