the ezrun motors are only 380 sized. my 3300kv ezrun won't even more cool on a rustler vxl geared for 35mph with 3s. but, then again, every motor has been running hot due to my stupid near-toast vxl esc.
They say a good mechanic only needs 2 tools - WD40 & Duct tape. If it moves, and its not supposed to, duct tape. If it doesn't move, and its supposed to, WD40.
Yeah its the 4300kv finned can also so its the 380 size but yeah 50mm long.
I would like to try a proper 540 size one to see if would be any better and run cooler but will see when i can get my hands on one to try it out.
The HSP buggy without wheels, esc and motor is 1.750kg compared to the Caster pro nitro buggy i have converted is 2.010kg so there is 250grms between them.
