The image name implies US Rockets SU F motor.

yep F100-8 they are pretty good at taking off surface mounted fins if you are not careful...these have the brown casing so they are from 91

Wow, 21 years old! Are they AP?

 

[RWmarlow]

Yeah they are AP "standard" propellant formula....Don't think "firestarters" ever had that high of an ISP

I have some AT motors from 1989 and a Crown from 1984. So AP have been around a while. I'm sure others have ones even older.

Most of the F100's I had shattered the casing, the lower thrust 24 mm F's didn't have anywhere near 80 N-s and the delays were very unreliable. Still have some F25's - good saucer motors :wink:

Probably "Butt Kicker" propellant.
I flew a few 29mm G something "Fire Starters" a bunch of years ago.
