I'm at 1150# empty and have an Aerosport IO-360 with horizontal fuel injection and the Hartzell c/s prop. I recently recorded the following numbers in cruise flight: Altitude 8500' , 19F OAT, 8.0 gph, 2400 rpm, 22.3" mp, 161 kts TAS and 144 kts indicated. The Skyview claims that I was producing 66% power according to it's internal database of Lycoming IO-360 engines. Do these numbers sound right? do not archive ________________________________ Message 2 _____________________________________ Time: 03:55:08 PM PST US Subject: Re: RV-List: Cruise Performance From: Kevin Horton On 2011-04-22, at 17:30 , mr.gsun@gmail.com wrote: > Hey Guys, I'm in the process of working out the new Dynon Skyview setup in my 7 year old, somewhat heavy and totally stock RV-7.

If you have the 180 hp engine, Van's performance claims at gross weight, adjusted to 66% power, would be about 166 kt. If you have the 200 hp engine, Van's perf, adjusted to 66%, would be about 172 kt. -- Kevin Horton Ottawa, Canada ________________________________ Message 3 _____________________________________ Time: 06:04:36 PM PST US Subject: Re: RV-List: Cruise Performance From: mr.gsun@gmail.com I ve got 180 hp.

I used them when I first test flew my RV8 and experienced heat problems. I also had the exphaust pipes ceramic coated which considerablhy reduced the radiated heat within the cowl. Note, it is best to ceramic coat the pipes before use, however they can be cleaned internaly .

My Dynon D-10A TAS reads about 7 knots low at 8.000' Density Altitude using something close to economy cruise power, and about 8 knots low at full thr ottle.
