SS67B-3 LIQUID FUEL ROCKET ENGINE KIT!!!
When the SS67B-1 was completed in 1994, our goal was to begin improving it. We wanted a version that was lighter, more powerful, more versatile, less costly, and easier to launch and recover. Our efforts led to the development of the SS67B-2, and now, the SS67B-3!
The SS67B-3 has several improvements over previous versions. The kit includes a separate casing for increased flight stability, lower engine weight, increased performance, fewer parts (oxidizer tank and fuel tank have been incorporated into one assembly) and is easier to fuel and assemble.
The engine has retained many important features of the B-2. It is completely reusable and the cost of propellants has remained at only $6.00 per flight.
