Bobby;
Great! You’ve made
that major milestone!!
Those temps don’t
look bad at all. Oil below 210 on climb with OAT at 80 is good.
It does seem that it should have dropped a bit further when level in the
pattern. But hey; this things progress one step at a time.
See you at
Cedar Park,
Al

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
