I understand this may only target a small crowd, but Brian - my mechanic in Texas - is having a new pilot's side sun visor made up for me with the Ovation3 Cruise Power Schedule on it (see photo). This is essentially the same data found on the 2500rpm 280HP Ovations, but has the 2550, 2600, and 2700rpm Best Power and Best Econ cruise numbers on it. I'm guessing those of you who own a 2008'ish Ovation3 from the factory should already have this. Those with earlier Ovation1, Ovation2-DX, Ovation2-GX, or Eagle aircraft who had 310HP/2700RPM conversions probably have visors with the "old" data.
Anyone interested in ordering one? They are (cough, cough) $330 each and take roughly 2 weeks to arrive once ordered.
I asked about them last year when my new engine and prop were being done, and was told they were hard to come by. For me, it "completes the picture" as far as my 310HP upgrade went, so although I see it as a rather expensive piece of plastic, it falls under "nice-to-have". If anyone is interested in one, please let me know and I'll put you in touch with Brian. He'll take your specific information and get back to you individually with logistics to complete the order.
