    Been trying three ideas, first is a fan at either side and it's driven tank style so both suck or blow (hahaha) gives fwd and bkwd, alternate directions steers. This has brushed motors for reversing one side. Doesn't give much power. Second idea is a fan pushing each way (ie 4) and you just start one fan to give desired direction. Lot of correction, nearly lost a finger. ***BUT*** uses big brushless stuff so LOTS of push. Third has been the best so far, big fan at the back for fwd and back, with another on the front at 90 degrees for steering. This drives pretty much like an RC car (ish). Still undergoing testing though.

    EDIT - even though I've been mucking about, I can't see the setup surviving the current crop of spinners that turn up every where you go. Tbh they're stiffling creativity. Even if I put the fans in a hardox box, I still couldn't afford to be rebuilding each time they got a big knock.

    This was another reason I never pursued the idea, I could never think of a way to overcome spinners with the design, no matter the exact method of movement (skirt, wheels etc). I do agree that spinners are somewhat stiffling creativity. Stops you being able to include a neat new idea, that is if you're wanting to have a serious attempt at battle and not be eliminated straight away. I'd hate to end up creating something but it ending up the joke of the competition i entered.

    Many ideas are almost impossible to protect against spinners, at least if you still want the design to be maneuverable and not look like a factory reject tank.
