Thanks Matt.
Back when these planes were the schnizzle I remember guys using the OS 140EFI and I thought the engine performance was adequate.
So....mebby there is a future for these kits yet. Recently, I checked the available pipe space for the ES pipe you have been using and there is plenty of room.
Sounds like a nifty winter project.....
Thanks again.
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)
