Hi Dan , very cool what this looks like is pages for retail use ( Ring Binded ). this brings back fond memory's for me as it was way back then in 1970 I discovered FSI Model Rockets. At that time my Brother Bill and I would see who's Rocket would fly the highest. then Bill comes up with an ESTES Cherokee -D and and man did that rocket fly Hi. Well I was at a small hobby shop in down town Utica Michigan , there I found FSI Model Rockets for the first time. the shop owner sold me a FSI Penetrator and pack of E5-6 engines.
The next time Bill and I launched, well let me say this: the Penetrator was now the new SKY-HI
Champion, it flew past the Cherokee-D and just kept going WOW.
FSI has been one of my favorite Model Rocket Company's of all time.
I still have several Built Models and even some Engines. the last time I launched an FSI Rocket
it was a 2 Stage Star Gazer, I used FSI D20-0 to an FSI D20-6 both engines work perfect and the
rocket was tracked to 3800+ feet. both stages where recovered. Not bad for engines that where
20 years old at the time. Neal
