i had my skyline for a few days and it worked fine. yesterday i put in all wheel drive and the drift stage 2 moter. once i got it all back together i went to run it. it works fine but once it gets like 10-15 feet away from me it looses signal. the antenna is hooked up and the controller antenna is on. i duno what happened. i think the antenna wire touched one of the batteries while i was installing the awd, but only for like a second. im not sure whats wrong with it or how to fix it.
