I just picked up a xtm x-factor and i'm having some issues with it. First of all, it has a 3rd servo for reverse/forward and the radio is a 2 channel radio, it has a R box on top of the reciever for a 3rd channel hook up, so how does this work? Next, it slips into neutral when i'm driving it, and it will not shift to 2nd gear, i tried adjusting the linkage on the 3rd servo to see if it would change and it did nothing. I can't find a manual for this truck anywhere online so any help or suggestions would be appreciated. Thanks
