REFLECTOR: Flight data - Was Props

[Al Gietzen]

 ****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.
