It is quite cheap and easy to build and does not require a lot of sklls. On top of this, the result is fun and very enjoyable.
Let's make RC pipes, people!
Step 1: Idea
You can use a variety of cordless drills for example. The same is with the wheels and the pipe. It could be shorter or with a bigger diameter. It all depends on how you want it to be.
I used two medium sized drills - some cheap ones to be honest. They were powered with 12V batteries one of which is in the RC Pipe.
