One of the 2017 competitors took off in a little over a tenth of the distance DRACO took[1]. Of course, a stripped down Cub is probably much less useful overall, but taking seeing it take off in ~14 feet is fun.
If you want to see truly insane performance (not that DRACO isn't impressive), look videos of fighters like the F-22 doing max performance take offs. Lightly loaded they can be off the ground in about 250m and supersonic before the end of the runway - and these are aircraft that weigh upwards of 20 tons.
