Ive got a new revo 3.3 and have run only about a gallon through it. It runs amazing but I intermittently lose my brakes and throttle for a few seconds at a time. I noticed that the throttle is twitchy unless I plug it dirrectly into the reciever in which case it moves very smoothly. If that is the only thing I have removed from the opti-drive, will it be dangerous to still use reverse or should I install the foc kit? I am waiting on an inline fail safe at the moment. Any info would be a huge help!
