[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
