Run in speed
I am planning on putting a UL 350iS in my CH601. The manual says to maintain 80% power for the first 15 hours. Could someone with a UL 350iS in a CH601 or 650 comment on the airspeed that results in?

One possible option for you is to run 80% of max RPM (3300) with ISA conditions if you need a starting point. UL use to have torque and horsepower charts with fuel flows but I can't seem to find them on their site.

Mark, found the power/torque curves for the UL350is in an older operating manual. Look like 2350 RPM will give you 80% of nominally rated 130 HP. If not ISA conditions this will be off somewhat but it's a good starting point. Good luck!

Not sure on the airspeed, however from the operations manual of the 350i, 72% throttle position = 80% power. I am running a 350i with Dynon Skyview which has the throttle position sensor displayed. I have not flown my 650 yet, waiting for permission to test in he UK.
