So I decided to convert my LST2 since nitro is just painful to deal with and here's what I came up with. Here's what I used:
Losi LST conversion kit (Now I know some of you are not fans of this but it's actually pretty good & it's given me some good results, no wheelies either)

MMM v3 ESC
Neu-Castle 1520 1Y 1600kv motor
Traxxas Mamba Monster ESC holder
So with this kit I was able to keep the mechanical brakes by using the 3rd channel but I have no reverse but that's okay, I hardly use it anyway. I've tested it with 4S lipo & it hauls, the 1520 motor is a torque monster can't wait to try it with 6s

I was really concerned of the wheelies but because of the aluminum side rails it added some heft to the truck so it doesn't wheelie at all

Here's some pics.
