What size do you suggest for a reasonable price engine that will handle it steady but slow with the fabric covering?
And not to get off the subject is the .46 mentioned too much for a Kadet Mark II? I trust RCKen's advice so I guess I would put aside the .46 and still get a .32 or .35 for the Mark II, and save the .46 for another time.
My specific suggestion under your conditions would be an OS LA 65. Last year I rebuilt an old wreck for a gentleman that had become a professional student without ever progressing for years. The chief cause was no real mentor and a long line of totally inappropriate airplanes for him to really learn, its a common story.
This airplane was hugh success for him and I built/restored it as I posted above no ailerons and the only concession of extra weight was oversized dubro balloon wheels. The engine was a ST 61 but it turned out somewhat cranky for him so a new la65 solved that and was an extremely user friendly engine for him as well.
On the Mk 1 or 11 no larger than a 35 and my favorte is a nice modern .25.
This is Larrys ride still with the ST:
