Looks like my hunch was right , after reinstalling stator 180 deg ive now got a very good stator magnet alignment and a centred axel. Quite shocking the manufacturer couldnt even assemble the...

Re: Scootabot

Front corners cut off getting rid of the weak welds ..looks better and stronger to boot.
After re cutting front down tube [ fork rake ] i hand filed mating surface so the fork/ wheel is perrrfectly aligned and i will hold it in place while welder tacks it.This is the most critical part now.

Hi Emoto, have you decided on your hub wheel yet?

Looking forward the rest of your build progressing :) YES finally decided on motor will post to...

Well the last two post's say it all for me atm , as relying on this qs motor for the extra kv i needed is a bit of a gamble. Add to that a more specific controller than your average foc is two much of a gamble for now, if i had close to kv needed id go for it, Heading in another direction now. Thank...
