nice sounding motor and punch
This motor sent up my Aerotech Arcas rocket to about 800 feet. It creates a nice crackling sound from exhaust and is very impressive. Cant wait to send up another F20.

Good Motors for Leviathon/Ventris/Argent/Partizon
Good economical motors for Estes PSII kits like the Ventris and Leviathon. I have flown one of these motors in each rocket. Slow but stable flight to 500-600 feet in each case. The 4 second Delay is about right for Leviathon/Ventris/Partizon/Argent. Has a little more push off the pad than the F27. Use a long enough rod/rail and don't try for a longer delay - 4 seconds only.
