Yah, and I think aerodynamic drag goes up at least by the square of the scale, but I am sure there are other factors like BrianG said, such as length, would affect the drag as well to a certain extent, and of course those HUGE wheels on our MT's/truggies and buggies.

"Seems "low" until you remember torque is much higher in electric. " BrianG -------- It's not that there is 'higher' torque, but it's that there is much more of it... over a very broad rpm range, and at 0 rpm, where it matters most.

I think we can assume that scale speeds and power to weight ratios don't match... obviously.
