Trying It Out..................................................................................................

Here’s the payoff to all your hard work: You finally get to see the little kart

zoom around your living room. Remove any obstacles before you start!

Follow these steps to operate your go-kart:

1. Slip in the batteries.


2. Turn on the power switch on the kart.


3. Point the transmitter at the kart and press and release the on/off button.


4. Watch it go!

If nothing happens, here are a few things to check out:

All the batteries are fresh, are tight in the battery pack, and face the

right direction.

See whether any wires or parts have come loose.

Compare your circuit with the photos in this chapter to make sure you

got all the connections right.
