120 mm motor under test
Alternative propellants for Isp up to 230-240 s are possible (not yet tested).
The motor is re-usable
The motor can be manufactured in different lengths, for burn times other than described above.
A performance certificate issued by ELMEC, Ploiesti, Romania, is available.
This motor can perform as O-class or P-class, dependent on the propellant used
It is suitable for high-power amateur rocketry
