The 'atmosphere' on the alt engine section of VAF is a bit less hostile these days, and someone has asked for real world performance numbers on flying rotaries. Anyone care to share? I'd like to think that the best way to improve alt engines' rep is to share honest performance numbers, at least when people are willing to listen.
For the data to be useful, you'd need to include a/c type, which engine configuration, whether c/s or fixed pitch prop, actual flying weight when numbers were taken, altitude, manifold pressure if available, and the biggie, fuel burn vs cruise speeds (very important to include altitude and specify kts or mph for cruise numbers). With starting altitude & gross weight, full throttle climb rate can help estimate actual hp the engine is producing.
The thread is at

or if you're not a member, I'll be happy to forward anything you're willing to share.
Thanks,
Charlie
