Ensure that the battery has been charged properly for the full four to six hours recommended by the manufacturer before using the truck. If you don’t, the truck will not last as long as expected.

If you charged your battery properly and it still seems that the time of usage between charging periods is too short (i.e. less than 10-15 minutes), consider replacing your battery.

The RC truck stops responding to the controller after it gets a short distance away from the user.

The battery of the controller may be low on charge. Try replacing the 9V battery of the controller.

There’s a chance that the antennae (the wires sticking out of the controller and truck that transmit and receive the your input) are broken. If one or both of these is broken, the truck will not respond. Check your antennae, and consider replacing them.

The RC truck does not respond to the controller at all.

First, try recharging the battery, ensuring that the charger is properly connected. If this doesn’t help, try replacing the 9V battery of the controller.

Check to see that the 9V battery in the controller and the 9.6V rechargeable battery in the truck both have enough charge and are plugged in properly. If that’s the case, then one or both of the batteries might be malfunctioning; consider replacing either the truck’s battery or the controller’s battery.

The truck isn’t turning well or is unable to drive in a straight line.

The truck may be having problems turning because of small obstructions in the wheel, like mud, gum, or sediment. Check the area around the wheels and remove any obstructions you see.

The front wheels often come out of proper alignment during use, and a quick fix conveniently is built into the truck itself. A wheel alignment adjustment knob is located between the front wheels, in front of the battery pack. Turn the knob until the front wheels are parallel with the rear ones.

If the knob doesn’t solve the problem, check the suspension (the springs and rods that connect the wheels to the chassis of the truck). If they look uneven, then try replacing either the front wheel suspension or the rear wheel suspension.

If the truck is having problems turning, there is a chance that the battery is running low. Try recharging the battery and, if the problem is persistent along with a short run time, try replacing the battery.

The turning problems the truck has might be caused by damaged tires, either because the treads can no longer get traction or because the wheels are misshapen. Check the treads and rims for visible damage and consider replacing your wheels.

The control servos are the part of the truck that reads your directions from the controller turns the front wheels. With the truck and controller on, check to see if the wheels turn accordingly as you turn the knob on the controller. If not, a replacement of the control servo is your best bet.

The RC truck is unable to reach it’s top speed and/or is slow to accelerate.

Make sure you are close to the truck in order for the transmitter to receive radio signal from the controller; the closer it is, the better it will receive your signal. Also make sure to be in a location with little to no radio interference from other devices.

If the truck seems to be slow, there is a chance that the battery is running low. Try recharging your battery and, if the problem is persistent along with a short run time, try replacing the battery.

The truck may be moving slowly because of small obstructions of the wheel such as mud, gum, or sediment. Check the area in and around the wheels and remove any obstructions you see.

If the front tires are turned even while the controller’s off, the front wheels are out of alignment. The truck wheel alignment may be adjusted under the truck. The knob to adjust the steering wheel is located forward of the battery compartment. Turn the knob until the wheels all the wheels are parallel.

The truck may be going slow because of damage to the tires. Check the tires for visible damage and consider replacing your tires.

If you checked all of the options above and your monster truck is still unable to go near the 25 MPH speed advertised by the manufacturer, the motor of the truck might be having problems. Try replacing the motor.
