How to compare gasengine size to outrunner ?

[What's_nitro?]

Oppressor, the Sentilon line of controllers are probably better quality than everything else on the Hobby City site. I have used one of those 100A controllers and it was great! As long as the truck is reasonably geared there will be no issues with cogging. They have a large heatsink as well, but mine never got much above ambient. I was using it in my Ofna GTP on 6s with a Neu 1515/1y geared for about 76mph (using mechanical brakes of course). I could light up all 4 tires (foams) at will.
