Sorry for not replying sooner. We are actually working on writing up everything about our propellant. We want to make a detailed "how to" like what Richard Nakka has.
The most important component is obviously Ammonium Nitrate. We mix this with about 10% Potassium Nitrate to stabilize it. We then add Magnesium and Aluminium. The binder is Polyurethane.
The motor was a 57 mm diameter motor with graphite nozzle. We had 7 grains (bates).
I will definitely send you a link to our report when we have written it.
Cheers,
David

Переводить не стал, думаю что все понятно и так. В принципе ничего нового. Ждем теперь более детального описания.
