    Yes, he does put on a very entertaining and informative show, and he does know his stuff.

    However, a proper 500-hour IRAN involves a great deal more than what he demonstrates at AirVenture. It...

    Two different issues, Bill.

    Case cracking is (and always has been) a known problem with big-bore Continental engines. I have never heard anyone suggest that pilot technique has anything to do with...

    Did you mean to say that there is NO reference on them as to what should be done when converting it back to a taildragger?

    I agree with Tom. I've not found an acceptable borescope costing less than $700-$800. I keep looking, though, eventually I'll find one.
