Some more Arlington pictures of Joe Hulls airplane.
"I'm still over prop'ed (too much pitch). My static is only 4200RPM with a
2.17 PSRU and level flight I can only get 5200RPM. A shallow descent I can
pretty easily get 5800RPM. So, I have some prop work and or tuning to get
more horses!" Wrote Joe Hull
The new wheel pants were worth 400 RPM as I recall.
What is the top speed up to know Joe?
There are always crowds around rotary powered airplanes.
Paul Lamar ...No rotor no motor.
The wheel pants got me an extra 400RPM - So, I'm now at 5600RPM and that
translated to 15-16kts (17-18MPH) increase in speed. I'm now cruising at
158Kts IAS - about 167Kts TAS (191MPH) at 3000ft AGL.

Thanks Joe, With 100LL reported to be over $4 a gallon...
....$3 a gallon auto fuel and a rotary engine is a huge
bargain :)
Please send us a fuel burn at that speed next time you get
a chance. A couple more pictures of Joes airplane.
BTW Joe replace those worm drive hose clamps with
constant torque hose clamps from McMaster Carr when you get
a chance. They are designed to work with that good silicone
hose you have on there.
For you newbies here is some more info on that.
