I've tried everything with these speed controllers and still absolutely nothing. After that flat out tragedy, I've decided I'm going to do it right and get myself a set of BotBitz hacked TZ85As (or hack them myself) and a 5s LiPo. And upgrade to 4WD.
Downside is that I might have already spent every last penny I own on the previous parts so that may be quite a while yet...

Until then, I'm going to get building this wood bot using drill batteries and the old, beaten up motors and speed controllers from HardWired. It's not going to be impressive in the slightest, but it'll make some nice splinters when it's done - might take it down to the next featherweight championships and pick a fight with 3 spinners like Tiny Toon did last year, for a bit of a laugh!
