Aerotech is introducing their first new 24mm SU motor since 2001 at NARCON, where I'm heading tomorrow. It's an F32T with a modified Blue Thunder propellant with a specific impulse of 225 seconds. It's 95mm (3.75") long - the same size and weight (65g initial with 25.8g of propellant) as an Estes E9, but with twice the total impulse (56.9 Ns). It's available in delays of 4,6, and 8 seconds and its burn time is 1.6 seconds. I'm gonna pick one up tomorrow for my 24m saucer.
