Subject: [FlyRotary] First Flight

It's done but not finished. First flight today for about 20 minutes around the airport. I still have a few odd tuning issues but Tracy believes it due to my MT electric prop and provided a different approach to try. My supercharger was mostly bypassed for this flight so MP pressure never got above 28". Take off rpm was at 6500 with the prop set for 2250.  It flew like a 190 hp RV-10. About 800 fpm climb. I didn't push it and limited speed to about 110 mph. Fuel MAP needs to be much better before using the supercharger or increasing the prop \ engine rpm.  I can run 34" MP at 7200 rpm and 36" at lower rpms. Still HP to be tapped.

A few data points. Engine was warm before takeoff because of a few high power run.

Takeoff  roll Oil and Water both at 191 F.

 800 agl  Oil 207  Water 196

 Pattern  Oil 205   Water 189.

OAT 80.

Gearbox oil exit 235 at the warmest.

Looks like I need to seal my air ducts. They are a slip fit now and most likely not holding pressure.

Thanks to everyone on this list. No way this could have happened with out this community for support. Special gratitude to the Austin Rotary Bunch. Mark S., Dennis H.  and Bob D.
