Anyway after some runs we could smell a very strong burning smell. Every time we have run this car especially while doing speed runs we have smelt this smell. To me it really smelt like an electrical burning smell. It was always a bit of a concern.
Anyway with a bit of investigation with our noses we worked out what the smell was. Turns out the big heavy savage works the mechanical brakes really hard. The brakes seam to be holding up OK even with the load. I'm glad I'm not running electrical brakes, not sure if everything would cope.

I think this shows several things.
Cooler operation means better effeciency and longer runtimes.
If you didn't change gearing, spool up time is about the same.
If you want to see a big difference, gear it up some. The 4 pole will easily outpull the feigao.
What kind of temps were you getting?
I would think electrical brakes would work just fine with your setup.
