New hi-speed project

[BrianG]

Don't know about much other than the vehicle itself. From what I've heard, a good set of foams may be the best thing to use, right? Then, mounting them so they are perfectly balanced is imperative at the speeds I'm going to try to hit.

If I can't get a 2spd spur/pinion combo right to reach those high speeds, I might have to go with a single speed and use a very large pinion. But then, I'll need a larger motor (1515 or even the 1521) to generate the low-end torque since it will be geared so high.

I think I'm going to try to make the battery tray and the ESC/Rx mount out of fiberglass to keep the weight down. Should be interesting...

The 1521 would be a nice choice. I will use the 1521/1.5Y to make my speed machine.

A 1521 spinning at that kind of rpm would draw LOT of current. Plan for some serious battery packs and asc if you want to pull 60K rpm with a 1521!!

I used my 1521/1Y with 37V and that was some awesome power. Too bad the drive train didn't hold up. The six gears inside the rear diff had a little melt down. I will eventually get this http://www.vertigoperformance.com/products_Lockers.html to save my diffs.
