UkerDuker, For 4 years I have been using this technuique and not one has failed. If you have a slight prop strike then you must remove the prop from the enigine and thougholly inspect it, ie. bend it, twist it and check that none of the seams let go. If one has a slight seam crack, then just toss the prop out and make a new one.

My ramp on the C-130 is not operational, but on my C-160 it was and also had paratroopers jump out.
