The Lancair IV has the same basic performance envelope as the Curtiss P-40; WWII fighters generally weren't known for gentle handling characteristics.Assuming you're referring to the turbine powered Lancair IV-P? Yes, a beautiful airplane, and I've always been a fan of the IVs. But they've got the forgiving stall characteristics of a Lear 23 and an engine out descent rate of something like 4,000 FPM.
A couple factors about insurability. Of course, the Lancair IV has a value much, MUCH higher than the typical homebuilt. That'll make the insurers nervous. Second, the Lancair IV has the highest fatality rate of all the homebuilts I've looked at. "Fatality Rate" defined as the percentage of accidents that result in at least one fatality. The Lancair IV has a 50% fatality rate in my tally. Considering that the owners are likely to be ummm, "prosperous" men, the insurer can end up paying a lot after an accident. Not surprised they're shying away.That's interesting data, Ron, and better than what I'd last remembered hearing (although what I last heard didn't involve your level of hard numbers-driven info). My recollection is that the things are exceedingly hard to insure, but that same sort of thing has been the case with a number of aircraft over the years and insurance cycles, including P210s. Meanwhile, there was a time when people could move up from an SR22 to a 421 with otherwise zero multi experience and get insurance, which isn't a good idea.
