if using lower kv rated motor temps be cool an no need for fan, but being as i'm using high kv motor an large pinion temps high on motor so fan helps level temp abit, i have cool down period after about 8 mins use as motor temps is on border line of safe
the speed is nice as tyres are reglued. Buggy was faultless as nitro going brushless made it bit quicker just need to find sweet spot with gearing/temp an stock up on lipos for it, been focused on hyper mini st (dogs truggy) BL conversion had going on whilst doing this so buggy not got any attention / goodies just used
if gonna use same kit i have u'll need to raise centre diff about 2mm so when motor installed not fouled by chassis an mesh be spot on, you decided on what leccy gear using?
