Thats a huge motor for sure. My Neu 2220 is more then enough motor for me. The sure power that beast will have I can only guess. What kv did you get for that thing?
I'm still running the fan on my motor, with no problems yet.
What are you doing for tranny upgrades, axle shafts, tires? Wheelie bar?
The motor is 750 KV. I'm following your lead and using PhatDad 5mm crossover bones and cups. The trans has all the HD option gears with a Turtle quick diff, Craftwerks titanium shaft. Not sure what wheels to use.
I did make a homemade wheelie bar using a Modified-RC v2 bumper and a Savage Flux wheelie wheel. I like the Flux wheel because it is larger and fatter than the stock Mod-RC one. Got a 5mm shaft for the wheel and am using Boca bearings and 6061 spacers to hold it in place. Hope everything stays together!
