Lately, I have been working on mountain trucks. So I thought I would write a blog about them. Here are some tips. This is the first RC (remote control) truck I have built that actually works.
THE STEERING
This truck you are looking at, actually doesn’t steer great. The reason for this is that I put the return to center on the motor not the wheels. (NOTE : The return to center is a rubber band or spring that makes the wheel return to the center.) Basically, put a rubber band on the bottom of your car like this and it should drive forward and turn with ease.
THE ENGINE
Most trucks that climb mountains have strong engines and are geared down. (NOTE : A geared down engine uses gears to make an engine go slower, but stronger.) So if you want your truck to climb, gear the engine down like this.
The gear on the left is connected to the engine and the other gear is connected to the axle. Here are two more things that might help you. Make the gear on the left smaller and the gear on the right bigger this will make it even stronger. And this last tip is not about the engine really but it is useful. For a climbing truck, the battery pack needs to be on the bottom of the car. Whatever you do, don’t put it on the back as it will tip the car over. I hope this has helped you.
