ok heres the thing. i changed the motor and ran the car for three batteries on that motor, then i changed the gears to 61 spur and 21 pinion, thats when it started doing this... Also i can turn both the rx and tx on and walk away with tx in hand when i get about 10 feet away it starts beeping and i get no response to trottle or steering. i think the receiver has had it... whats a good receiver for the jr radio xr3i. i plan on going brushless in the future.. thanks guys for all the help with this problem..
