Yet another deviation. :) Since the motor is so high, the ESC couldn't mount in its normal place on the chassis right above the motor. My adaptation is a piece of UHMW cut to size and mounted above the motor and servo. It now holds the ESC and RX. The horizontal screws hold strong, but I don't trust the veritical ones. My plan is to run longer bolts all the way through and put a nut/t-nut on them.
