I'm currently doing a build diary for oOple for a brushless conversion of the Hong Nor X1CR, just waiting on a couple more parts from the US ..
It should be a good guide for conversion of any 8th buggy including what electrics and where to get them (majority are from the UK).
Jimmy will oOpleify the report and it'll be posted in the next few weeks..
Any questions PM me and i will try and pass on any info i have learnt so far...
