I just bought a TQi 4 channel radio and am having some trouble getting it to work with my revo. I'm probably just missing something so hopefully you guys can help me out. Its a 6507 model and the old style 3.3 revo if it helps. Anyway when I hook the reciever to the optidrive the only thing that works is the steering, no response from the throttle or the transmission shift. I found the instruction very vague as far as initital installation but I'm most likely missing something obvious. I've seen some posts on bad recievers out of the box......hopefully this is not the case.
