Great to hear, Bobby!
A long time coming with your share of
frustrations – and it seems some installations simply take a bit longer
to get completely sorted out. Looking forward to seeing it later this
Month.

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.
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.
