Hi! All
Since I converted to Trike (Sorry originally built a convertible! ) I threw
away the long mono-push rod to control the flaps and fitted the flap motor
system . If I remember correctly the trike take off setting is 18 degrees
verified by a natty visual indication from the P1 Position
actually printed on the port side flap upper surface.

Now here's a thought.
Has anyone out there tried decoupling the flaps and gear on a monowheel and
using
the tri-gear flap motor to deploy the flaps? One can see why full flaps are
desirable
on landing, but mebbe only 1/3 flaps are really required on takeoff.
I seem to recall that the original 912/fixed pitch classic had barely enough
oomph to
take off at sea level. The 912S addresses this, and the 914 at high/hot
conditions,
but Terry's T/O problems sound frightening...
