There have been more engine prop shafts with electrical tape wrapped than there have been airplanes, I'd bet. Anyone that has been around awhile at all remembers when NO props fit ANY shafts..... So .... electrical tape seemed fine, and was used on 30K rpm engines with no problems.
I think we've just gotten pick-ier....
(I shim the PROP hub for my Brillelli's, using CA hinge material. Works dandy.)
