POS INT,
Richard Westnot
NewTimer,
With regard to the performance see below some real-life pictures that essentially confirm your numbers. Our P68 makes 142 kts @ 65% power @ 4500 ft (500lbs below MTOW). Note that:
1) this was without wheel fairings which would give you an additional 7 knots, rather considerable. (While go get then about the handbook speeds, the P68 however looks much nicer without them and their possible use is depending on the RWY-conditions)
2) Number 1 engine is brand-new (4 hrs when the picture was taken, 2 weeks ago), requiring rich fuel-flow
And Yes, there are two issues:
1) the fuel cocks as NewTimer rightly tells us:
a) different P68 may have quite fuel different systems, watch that!
b) you may not select what you think you do, since the cable link between selector and actual valve is "soft", can misalign, and has no detent.
2) the air-intake icing. Alternate air should not only be actuated in actual IMC but when IN VISIBLE MOISTURE (placard!)
I wish everybody many hours in this lovely plane.
