REFLECTOR: Flight data - Was Props

[Rene Dugas]

My Wingco wing turned right with incidences the same on the leveler.  I
decreased the left wing incidence and when I got to level I split the
difference and shimmed each wing for level flight.  Unfortunately I had
to re fair the leading edges to match.

 ****That’s with a 260 hp 3-rotor rotary engine****

 

How's that working out for you Al?

Had the plane in the air for ½ hour yesterday, basically orbiting the
airport at about 3500 MSL (DA about 6500’); OAT of 90F.  With my
augmented inlet scoop for the oil cooler, the engine temps were fine.
Basically no envelope expansion yet, cruised level at 65-70% power.

 

Typical data was 2050 prop RPM, TAS 160 kts (IAS about 145 kts).
Estimated power setting about 60-65%

 

Continued problems with RWS engine controller (EC2) – spurious data
setting changes.

 

New problem is tendency for turning to the left – right control input
needed to go straight, some right rudder needed to offset adverse yaw
due to the aileron input.  Seems clearly a wing incidence issue.
Incidence checks with the gage shows both wings to be exactly the same;
however, I have known since installing the wings that this was a concern
because the leading edge profiles of the Wingco wings are not the same.
The incidence is going to have to be set by trial and error.  Major
bummer.

 

But, hey; it was up there flying, looking great and sounding great for a
significant period of time, and came back safely.  Have to be happy
about that.
