I am running a Mamba MAX 5700 BL system in my TC4. I love it. The motor never gets warm, nor does the ESC. There are a bunch of 540 size BL motors to pick from, just pick your favorite BL car ESC.

I dont have time for motor maintenance AND i had the BL system just sitting in a box, so that is why I used it.

I think long term, BL is cheaper, plus a lot less "motor involvement"

URC
