You should now have a driving and turning RC powerwheels car. If you have a 6 channel remote control, you still have 4 channels left to do anything you can think of. I used one of them to make my clown turn to look at people. (He actually turns to point the water pick gun at people). I had a right angle motor from a surplus store. This is in the picture below and I made a PVC adapter and set screwed it to the motor shaft. Then I used PVC pipe for the clowns torso and this fits right into the motor shaft adapter. For controlling this I used a sabertooth 2X10 RC. ( I know you think this is too expensive and it is if this is all you're doing with the components, but I'm sure you will think of other uses. I have used these parts on 25 different projects and just keep rotating them from one thing to another.) Wire this the same way you did the drive motors and wire the power through the main switch like with the sabertooth 2X25. This way everything turns off with one switch. I used the rudder channel of my RC controller to turn the clown left and right. The other side of the sabertooth 2X10 will be used later. (for the arms)
