here is the dialled setup...
LRP Shark 18 'Monster' Factory Team - then take the rear roll bar off
Buggy Body
LRP VTEC 35 shore foam tires ('front' 26mm wide ones)
LRP VTEC 1800 LiPo
LRP 'servo hold down' plate
10th scale servo, I use a 'low profile' one.
XRAY M18 servo saver
Deans Connectors
I actually use a novak 8.5, and she is silly quick
but 10.5 is probably your best bet.
an LRP blue heatsink to side the orange logo on the motor :P
the Sphere TC will fit, but without the fan, but cutting the fan off will void warrenty. you have to mount it fairly square on the top place to get the heatsink under the main bulk of the cockpit
