You're welcome Dave, but really, you would want to try it first. And when you do get some results, please report back.

Besides Bob and me, I don't know if anyone else has their pattern models flying yet. There's a ton of flying info on the sport thread for the SAP with sport models on mufflers and small props, but very little flying experience on pattern models on piped set-ups with pattern sized props.

I dabbled a bit with the EF Extra/SAP/pipe. This plane is much larger, heavier and draggier than anything pattern related. I found that a pattern prop on that plane was not as effective as a larger diameter lower pitch like a 19x8....allowed higher spool up and better thrust (but noisier too)
