Redcat Racing Weekly FAQ


I installed batteries in my car and in the remote control but when I turn on the power switches the remote control doesn’t seem to work.


This is a very common problem. If the batteries installed are not fresh or fully charged rechargeable batteries, the controller will not operate correctly. You may have some things such as throttle working but no steering. This is usually due to batteries that need to be replaced. We recommend rechargeable batteries.

Also if the red and green light on the remote control are not on when the switch is turned on there might be a problem with the battery connections. If this occurs and the batteries are fully charged or new the terminals in the controller battery box may need to be bent out a little to make better contact with the batteries.

If changing the batteries did not resolve the problem, you should inspect all the wiring on the vehicle. You should check the receiver to make sure the steering servo and electronic speed control are plugged in correctly. You could also try swapping the 2 plugs going into the receiver to see if that fixes or changes the problem in any way.

If none of the above options resolve your problem you should return the remote control unit to us at 3145 E Washington St. Phoenix, AZ 85034 and we will gladly swap it for a new one. Please include a written note with your shipping address and the problem with the remote control so that we expedite the replacement.
