Webra 91 P5
Apc 16X6, Byron 5% nitro 18% oil, home brewed quite muffler, about 75 degrees with moderate humidity. 8850 rpm a little rich.
At peak rpm the setup on a Funtana 90 gives 89 db @ 9 ft.

RE: Webra 91 P5
The engine is smooth and the throttle is very linear. I tried to get the db lower by using a Dubro mount but that was a waste of time. The airframe is like a huge drum. If you talk loud next to the wing it amplifies your voice.
