I’d also question the location,
angle, and condition of the pitot tube.

Subject: Needing performance
information on the Lancair 200 and 235
A close friend has a pristine Lancair 200 that he has asked me to fly
and then render opinion on the aircraft's performance. It looks
great and has obvious excellent workmanship in its construction. After a
thorough annual condition inspection, I flew it and found that it was seriously
lacking in power. In fact, with just 10 degrees of flaps and gear
extended, it never accelerated beyond 60 knots (though it was
simultaneously rising at about 400 ft per minute). I didn't immediately
retract the gear because I was concerned that the plane was flying just above
stall. In the traffic pattern, I retracted the gear and got just 78 knots
- still with 10 degrees flap. I landed uneventfully. There was
no abnormal balance or control of the airplane and, in fact, its construction
symmetry is nearly perfect. Jack test of the landing gear showed
completely flush retract of gear and doors - not likely that something was
dragging. This plane has an 0200 engine with 9 to 1 pistons
producing some extra horsepower; perhaps a total of 115. Its prop is
a light weight (27 lbs) cockpit adjustable, electric IVOPROP.
Does performance sound right for such an early version
aircraft? Who has had experience in these underpowered planes? What
performance numbers should we be seeing? Without more power and speed, I
would be reluctant to take on a passenger for flight. Greg Nelson
