It always depends on the user, lipomax, and I still think it would be possible to take down the 4.5 with the 1920/4 and not the 1920/5- who would want to use 12 cells, anyway- a good controller, high capacity lipo packs( like 6000-8000mah) and a gear ratio that would make your car go over 45mph easily at 8.4V. However, I cant argue alot since you'd used the thing. You said that you'd used the 12.97 esc with the 1920/5 and it thermalled. I think that problem would have been evaded with the Warrior 20120 controller or the MGM 12012.

It all depends on how much would you pay to go fast. I might go for a reedy neo one, but not a Novak.

I can't really comment on the low turn 1920s on low cell counts,mine is a 10 turn on higher voltage so i just figured that the 5 turn would work well with 6 cells but apparently not.I use mine with a 18.97 on 3s most of the time and i can 't really get any heat out of the motor or controller.

Thunderbruiser,it depends what you're looking for,i don't think a system that's faster than the 4.5 on 6 cells but also does runtime and not just pure speed really exists,two different things really on only 6 cells.If runtime is what you want then maybe a slower turning motor like a basic5300 or a 1920/6.Some more voltage would achieve both easily though.
