RE: MagnumR dolly
I put the APC 8x8 prop on and shortened the header by 1 inch per directions. I leaned the engine out as much as I could on the ground, but upon launching it barley got off the dolly, not near as much pull, and in the air it was way slower then the 9x7 prop, probably only around 100mph. Any ideas? I can't lean it out any more it will shutoff on the ground before I even get it in the air. Richening it of course, just lowers the RPM. I am getting some smoke in the air, so its not too lean. It doesn't even sound like its getting as high of a RPM with the 8x8 as I am on the 9x7.
