High-Altitude Applications In high-altitude flights, in other words greater than 20,000ft, the chances for pyrogen to ignite in its entireity and thus produce enough gas to expel the recovery system drops dramatically. If, at this altitude, your drogue chute fails to eject, it will mean disaster for your rocket. As your rocket is tumbling or ballistically diving towards the ground, your main chute may eject, but the speed of the descent would be so great that it's likely that recovery system will fail in some way as well. With CO2, there is only a small amount of pyrogen and it's packed in such a way that it will ignite fully and the system will work as it should at any altitude. The gas that ejects the recovery system is compressed CO2, so you're not trying to rely on large amounts of black powder to produce enough gas to expel the parachute. Safety increase, particularly for large diameter rockets. The larger the recovery compartment, the more gas pressure is needed to expel your recovery system. In most rockets, the ejection charge is a black powder contained within a vessel, whether that be, in smaller motors, the actual motor or in the case of dual deployment and larger motors, a separate ejection canister. As the scale of your rocket goes up, so does the amount of BP that you need, as does the risk of premature ignition. With the CO2 system, you can seriously scale back on the amount of BP needed to eject the recovery system in large rockets, increasing the safety of your rocket and set-up many-fold. Cleanliness The relatively miniscule amount of BP/pyrogen in your rocket will nearly eliminate the burnt smell and residue inside of your rocket*, as well as keep your parachutes from burning. The CO2 in the canisters is clean and odorless, resulting in less cleanup time for future launches. *Well, it won't add to it. Whatever smells were in the tubes before you used the CD3 are not our responsibility. It's just cool. While this product is primarily aimed at larger, high-altitude rockets, once you've got your kit, you'll want to use it on all your low-altitude rockets too! Yeah, everyone can pour some powder pyrogen into a canister with some tape, but you'll be ejecting your parachutes with class. Disadvantages It weighs more than your standard ejection canister. It's all aluminum, so it's relatively light, but it still adds weight.

It's more complicated to assemble than a standard ejection canister.

It's more costly than an ejection canister & pyrogen (?) It's got a higher initial cost than an ejection canister & pyrogen (?)

It won't fit in small rockets - minimum diameter is 2" (50mm).
