Default RE: Webra 40Q with Nelson ultrathrust short pipe
Bob, I ran the engine today with the new muffler,it turned 18,000 with the 8.75x7.5 and 19,000 with the 8.5x7. The plane is quite a bit faster with either prop,I'm guessing around 120. I plan to experiment with more props, do you think the 8.75x8 or 8.5 will get me faster with the scatcat.
