Yes there is very little room for BL motor movement. Need to have lots of spur and pinion gears to come up with the right FDR and still have proper gear mesh. I guess the best way to describe it is the motor is almost in a "POD" compartment. Brushed motors would probably be no problem though.

And the car is really light. Have to add a lot more weight to get it up to 1525g.

Just waiting on my 17.5BL motor, but I am hoping I get to run it for the first time this Saturday in a series race at Carolinas RC in Charlotte, NC.
