So I have had nothing but problems with my RTR Motley Crew boat since I purchased it. It will run fine for approx 5 min and then it will go crazy. Motor goes full blast even though I am not pushing on the throttle. I have sent the boat in for repair and they could not find anything wrong. I requested a new boat (and got one) and replaced the ESC in this boat but I still have the same problem with the boat either completely stalling or going nutz. I am running Lectron Lipo batteries 7.4v 5200mAh 50c on the stock 60amp esc.

Any help would be appreciated
