Hey guys I am new here and i got some questions if anyone can help me. So I got a hpi rs4 thats all I know about it really my local hobby shop told me the motor was pretty much done. So I started to rip it down and want to convert it to electric. I have pretty much have what i need to get it together but i kept the middle transmission mount and flipped it to the other side now my question is for the transmission i took out the smaller spur gear and kept the bigger one but like i see with anyone else who has done this the gear only goes one way is there any way to get it to go forward and reverse or do i need to go get a new shaft, spur gear and what am I looking for i am lost on this to continue it.
