I still have a Midwest kit magician I built in high school back in the mid-70's. Its been recovered 3 times, had a couple of cloth hinge replacements, and one control system/leadout refurb. Still flies well and has never been crashed in many hundreds of flights. Its been repaired, but only because it was flown sooo hard with some stout combat engines the softish main spar cracked a couple of times.
