Thanks for the kind offer.
I already have a R1 Pro in my CAT SX though (they are the nuts!) but was hoping to get the caster its own esc and put it in an alloy case to help with the cooling due to load of 8th. If worse comes to worse I will just swap my R1 Pro between my CAT and this until something permanent is sorted.
The Tekin Rx8 is not due out in time for my review sadly.
This 8th electric business not cheap, unfortunately
