George--

Thanks for the speedy reply. To answer your questions:

Tire pressure was 42 in the nose, and 60 in both of the mains. Curiously, Lancair doesn't have a recommended tire pressure for the Cheng Shen tires with tubes (that I can find). I believe the consensus around here is 50 in the nose and 70 in the mains so I was a little low. I'd sure like to know the proper values... FWIW, I had 50/70/70 of nitrogen in the tires last November so in 7 months they all lost about 8-10 PSI.

Nose strut pressure was sufficient to achieve a 1" squat" from full extension - somewhere around 180 PSIG (The log book is at the hangar). The strut was factory rebuilt nine years ago and has been pretty much sitting ever since. Perhaps I should rebuild it just on general principles.

The CG for the first run with 9 gal. in the header tank and wing tanks empty was near the forward limit. The CG for the second run with 10 gal. in the wings was 1" aft of the forward limit.

Takeoff technique: I was holding the stick aft since my original goal was to find out at what IAS I could lift the nose. I never got fast enough. I was focused on staying out of the weeds but I believe I reached 50-60 KTs indicated.

I just spoke with "Larry" at Lancair and he said it sounds like my mains could be out of alignment or a brake could be dragging. I'll be checking both those items tomorrow. If I was reading Larry correctly, I don't think he believed the problem was the oleo strut.
