calum- yeah i changed the bearings for needle rollers and a bigger shaft and it seems ok so far...made up a spare set too lol

Jamie- yeah its getting there, did the hard bit today, need to spend another hour on a lathe and it'll be done same design as the old one, but the shaft side of it should be a bit stronger....might change the brushless motor for a higher KV version... i want to hit over 10,000rpm with it
