I never understand why people loop gliders designed for competition. Grab a club 21 or Grob or something less slippery with a bigger spar and have fun with that. Or even better, pay to go up in a Decathlon with an instructor and actually learn something in the process.

All that looping a slippery glider gets you is an awful butt-clenching sense of "Oh **** Oh **** Oh **** Oh **** Oh ****" as your eyes jump between the bending wings and the clockwise acceleration of the ASI.

Looping a competition glider makes as much sense as turning the engine off on a Pawnee and trying to soar it. In both cases, you're using the wrong tool for the job.
