I concur, the Lancair doesn't appear to be an ideal aerobatics platform, partly because of the lack of an inverted oil system, but equally because of its super clean profile. I get the sense that once the nose is pointed down, you have very little time before the plane will reach VNE, left unchecked. My non-aerobatic descents have already had me at 220kias without any effort (or significant pitch) at all. For a full range of aerobatics, I would certainly go find another airplane, but for a select few maneuvers, it seems like a reasonable ship. My primary concern now is that of the health of the attitude indicator. If anyone has any evidence that exceeding 60degs of bank has no affect on the long term health of the AI, please chime in. Otherwise, I'm going to assume that it's not ideal for an IFR aircraft. Keith
