<< Humm... the Large 98mm/100mm "M" hybrids sound like more bang for the buck
at half the price. and more places one can fly it ! >>
Yep. Or you could get one of the cool new "tribrids" from RATTworks. Starts off
as a hybrid burning NOX and plastic, then switches to a liquid burning NOX and
alcohol. Very simple, safe and reliable.
right now we are in the beta testing stage
goto for a very cool motor tutorial

The SS uses 50% hydrogen peroxide and gasoline fuel. I haven't
seen the system myself, but I've red reports from those who have,
and it's apparently rather a kluge, and complex to operate.
Preparation for a run apparently involves casting a small
"igniter" grain out of something like sugar/KNO3, preparing
a paste of KMnO4 and coating the inside of the chamber with
this to decompose the peroxide, and dropping small, weighed
chunks of dry ice into the propellant tanks to evaporate and
provide the feed pressurization.
The payoff for all this is evidently a rather low performance
and an exhaust containing large quantities of sooty smoke and
It sounds like its main virtue is the "coolness factor of liquid
fuel. As some have suggested, the RATTworks nitrous/alcohol
"tribrid" is a much more practical setup if you want to burn
There's a difference between futzing due to lousy engineering, and futzing
because of good engineering, and a performance "payback".
The SS67B is rather poor engineering. You pay a lot of money, and futz
a lot, for very little return.
Brother Anthony of Cesaroni told me that one of his intern students fired
one of these at CTI a couple of years ago. The results were dissappointing.
