Dick,
When you get your 6904 you may have to file the motor mounting holes. I had to do that to get my motor centered. My setup (het 6904 with 2w-20) is running now on my test mount. Did some finish sanding to fix the scrap damage. With a mystery 2800ma 30c, 4 cell lipo, 60amp bp esc, I get about 48 amps peak and about 550 watts. That wasnt on a full charge, I'll try that tomorrow.
