What is a safe ground hit velocity for a hard desert floor? Is 20fps a magic number?

Please share your actual experience with safe descents or broken rockets--and their speeds.

My data from Mudroc this year:
  • Estes Argent G64 (475g dry weight) 20 fps (simulation figure) no damage
  • MadCow Scooter (240g dry weight) 21 fps (simulation figure) no damage
  • Madcow Piranha (850g dry weight) 19.7 fps (from altimeter data) no damage
  • GLR Vertical Assault (2700g dry weight) 23 fps (from altimeter data) no damage... well unless you count the scratches from being dragged across the playa.
  • Wildman 3" (2900g dry weight) 60 fps (from altimeter data) - knocked fin off. Guess it was in a hurry to return to earth and skipped the part where the main deployed. :facepalm:
 
Tim: thanks, see you lunch today!

John: thanks, see you on the playa!
