PA what a great find of a wonderfull old airplane and seems to be well built as well as attractive. The fact you will be doing the maiden on the ship that was built by your father in law gefore his passing makes it even that much better. I love these kind of stories of refurbishments or recoverys.

Noveldoc did nail the airplane. I have currently flown a MK 11 virtually the same airframe but a different tail shape and ailerons as stock with a plastic cowl that I donated for a prize at one of our events. The gentleman completed it with a LA 46 and this engine makes the airplane a bit of a rocket and not as much fun to fly as say another I flew several years ago with an appropriate modern 25, an os FX. The Kaydet MK 1 or 11's are smaller airplanes that a typical 40/46 trainer and overpowering them take away some of the character of this excellent trainer. I would suggest the same as I did in another thread just the other day with a Mk 11 and the perfect engine for these airplanes would be either the new .25 or .35Ax. The magnum is really overkill that will make the airplane less than it could be.
