I made my own model from the aircraft data and received a CG 128ft aft of where i thought it might be. My resolution was to put the pilot
seats 5ft in front, 2 passengers 3.5ft in front 2 passengers 3.5ft behind CG and the cargo 5ft behind. Oddly enough i get a lovely balanced
plane :D
I'm glad someone likes it too. What does it for me is the turbocharging, and the way it flies 30inches MP(75% throttle), 2400RPM (66%
prop), 100pounds/hr fuel(19% leaning) at 22,000ft . I would go higher ie 25,000ft but with 4deg pitch up on a full tank dropping to 1 degree
pitch up (Maybe worth a step climb?)
My favourite features after another flight have to be the sound when its leaned and you hear the engine rasp, its so smooth the transition
from virtual engine cutout and rasp, to the roar when properly leaned. The other favourite is stalling to a lesser extent when you can feel
the yoke shake and the aircraft as the aerodynamics fall off, and spinning it at 12,000ft. Fail one engine, feather it,give the aircraft an
incentive to spin inverted, and it falls over not well but its at least it looks like a spin, thus practicable for engaging brain on recovery
process.
