So I decided to motorise it with the help of my friend Barak.

A friend (Barak Yehuda) and I are working on a project and we needed a simple position controller for our 3 phase brushless motor. We couldn't easily find one, so we decided to make our own using an ESC.

Errata: The over-load fuses are up to 5[A], not 10[A]. The overall maximal current is 10[A]. So I put them in parallel to divide the current that passes through them by 2. My oil-filled radiator suddenly stopped working, I opened it up and replaced the over-load fuse. This video is a step-by-step of the fix. Hope it helps.
