Thanks for all the responses.
It just seem strange to me that a certified NRA motor would just go away that fast. Plus, the kits would most likely sell in todays market. Semroc ( along with others) have shown a market for the older kits.

I did not know that Quest and FSI had a link. I have been waiting to see Quest's new "D" motors, so may be we will see larger motors from them?

I still have some F100's and they were like 50/50 at some launches. But FSI D and E motors where great. Nothing like my old Echo 1 going up on two E motors. Those were the days.....

Keep the information coming, hopefully I can get a better understanding of the history of FSI.

Thanks,
Bob
