John sold Rocket R&D to a couple in Illinois.
308 E. Elm
Urbana, IL. 61801
They have a pretty good set of products; Aerotech, ISP, THOY, etc. I
talked to the new owner and he has been in the hobby for over 30 years.
I like them because they carry THOY products, which I think are great
kits. They also take Visa/Mastercard so you can "close the deal" over
the phone. All in all a good place to buy discounted rocket stuff.
