Been fiddling again.
For farm strip flying, I've taken to using the Maule 270 Tricycle. Good
145 kias cruis plus low stall speed and excellent takeoff acceleration.
All, apparently, true to life.
The only snag is that I greatly prefer the looks of my usual VFR steed,
the APM 20 Lionceau Cub. It's low wing and sleek.
In an attempt to have the best of both worlds, I decided to produce an
FS variant; FS standing for Farm Strip. The idea is to have Maule
performance in an APM20 package. This has required, amongst other
things, a change to the prop, retaining the original but converting to
Constant Speed. In turn this has needed a change from the APM20's simple
RPM gauge to the Maule's MP and Prop RPM gauges.
I've tweeked the power unit to give me a 145 kias cruise, as confirmed
by both the APM20 Airspeed gauge and a glass Lear PFD, which sits on the
co-pilot's side. The snag was that this took me into the amber sector.
No problem; I substituted the Maule Airspeed gauge. BUT; it reads about
20kias higher in the cruise and 10 kias higher at the top of the white
Am I missing something basic?
The alternative is to look for something else using a gauge that goes to
145, without going into the amber.
