RE: accelerates by it self
i think it is the transmitter, i have about 4 of redcats transmitters and out of 4 maybe only of them work, and they are brand new...they are very very cheap made... sounds like the batteries in the bottom of the tranmitter are coming loose and not getting a good connection as all time.. i bought a old red cat off ebay that came with the old school tranmitter and i have enjoyed it more than the new crap ones that are out.. shouldn't be the cystals. u can get any 2 channel tranmitter, i would go with traxxx
