Just following a link to one of those c5056 270 kv sensored motors…looks interesting for <$50.
then I found this Hub + vesc (china)
and these vesc mod uk
The uk vesc looks interesting. looks like they put all the smd componets on a single sided board and then the hv (Mostfets, shunts) stuff on another, connected by headers.
then a huge heatsink on all mostfets.
jst thought it looked interesting…
