My friend just picked up a used X-Factor (1st one) with extremely low mileage. The original owner had no other R/Cs & couldn't figure out how to reset a servo saver plus didn't realize the receiver batteries needed changed occasionally. That being said he probobly didn't switch radios. The engine runs great & all electronics work. Here's my problem.... How do I reverse it from the controller? Forward & reverse work on the truck but I can't switch it from the controller. As far as I can tell there isn't a switch for reverse. The radio says it's a Hitec Sport LYNX. It has two trim switches, two servo reversing switches, steering wheel, trigger, power switch.
