    Perhaps I need a few more hours with them, but I have found operating them in the C172 I fly to be a bit difficult in turbulence, i.e. lots of wrong...

    So how would one go about converting their license to a standard one that doesn't need an internet connection? I don't recall this being an option when I installed SW.

    Holes cut by a waterjet also have a rough surface finish and taper slightly, especially if the material is thick. Be sure to leave enough material to ream the hole to final size.

    I don't know of too many aircraft manufacturers using Pro-E; in fact, I can't think of any. CATIA is pretty much the industry standard at this point.

    I am not aware of any STC that lets you put Imron over fabric, and that paint is likely part of your problem. It gets very hard and brittle after some years, which is not a problem on a car body...

    In my area, aluminum scrap is currently 35-75 cents/lb. If it is all one alloy, you should get a higher rate (also alloy dependent).

    At any rate, you'll get more money than you would by throwing...
