Our economical EMKs include all the parts needed to build your own motor reloads, using pre-cast RCS propellant or your own formulation! Just add propellant, delay and ejection charge (if used) and you are good to go.

NOTE: For the single use EMKs, we recommend a maximum operating pressure of 500 PSI for the model rocket EMKs and 800 PSI for the high-power EMKs.
