Yeah i'm buying it more on his reputation and the experience people have had with his past controllers. Think after that i will just about have all my parts.

One thing i noticed in the wotty100 instruction he sent me was to use a power breaker in the supply line before the wotty100. Whats he refering to here?

Also what size grub screws do i need for locking the gearboxs on drill motors, is it something like 8mm M5's?
