Hey all, did not want to highjack this thread however 2a+ron posted that I built this motor. This is correct I have work for Paul Yaw of www.yawpower.com building rotary engines for the last two years and with Paul's blessing started www.azrotaryrockets.com. I am really proud of Darkslide he did a really good job with this car. We hope to see him kicking a$$ for a long time.
