I just ran up the engine today with the Silver Bullet Gary made me and I was a bit dissapointed to see only 1900 RPM static. This is well below the 2850 that I REALLY need, so I may not be able to fly this propellor. This could stall the first flight for a while. I'll most likely do a few High speed taxi runs down the runway and see how long it takes to get up to 60kts. It may be that it just needs to wind up a bit for the torque to pick up. I've emailed Gary Hertzler on the issue and he's ready to help, so stay tuned.
