Motor Equivilent

The biggest thing to consider with brushless motors in heavyweights for both drive and weapons are its thermal mass. An ETEK or other large brushed motors have a very large thermal mass and can be pushed to their limits for far longer periods before getting too hot and burning up. This means your brushless motors really need to be highly overpowered and geared correctly for the job they are doing to ensure they're running under far less load and in a more efficient state to minimise heat build up. Warhead runs the Scorpion 7050 motor with good success on the disc.

Did you modify the mounting at all? For all the motor's 10KW and 1.7Kg weight, Scorpion still uses M4 screws to hold it down.

Gearing motors to save them.
Due the higher RPM of the brushless motors compared to brushed motors (6000+ for the Rotomax 100cc @37V) you can gear 'm down more, making the workload a tad less straining.

Nick, the scorpion motor had an extended shaft made on the rear of the motor with a flange that bolted on the rear case to help minimise the outer casing from flexing and had a rear bearing to take the stress off the front bolts.
