If you gear the setup for around 40mph, the higher motor rpms may not be an issue. I have run my 7xl on 4s, considered a "hot" motor, in an 1/8 buggy geared for 37mph and never had any issues. I had a RCM heatsink on the motor and decent ventilation, but no fans and it never beat 160f. Feigao run hot, but it never gave me an issue and the buggy is heavy with a 10000 4s pack in it. If you have everything, give it a try and keep an eye on temps during the first runs. You may have to put a 12 tooth pinion, or less on it to get the correct speed, but the motor will not work as hard, due to the gearing.
