Quick Answer
Use the AeroTech Ejection Charge Kit when you need a reliable, consistent black powder charge for motor-ejected recovery on high-power rockets. Install the 1.4g charges in the ejection charge holder, follow all safety rules, and verify your motor's delay before flight.
Why Use a Dedicated Ejection Charge Kit?
A dedicated ejection charge kit takes the guesswork out of recovery deployment. Each charge is pre-measured at 1.4 grams, so you avoid the inconsistency of hand-measuring black powder. This consistency helps ensure that your parachute or streamer deploys at the right moment, reducing the risk of a lawn dart or a premature separation.
The kit also includes 1/2-inch ejection plugs that fit the EFC ejection charge holder. These plugs keep the charge securely in place, so you don't have to improvise with tape or other materials that might shift during flight.
Understanding the Trade-Offs
While the convenience is real, there are some trade-offs. The kit requires HAZMAT shipping, which adds a fee and means you can't get it with standard ground delivery. Also, because these are high-power motor components, federal law prohibits sale to anyone under 18, and the seller must verify your age before shipping.
If you're new to high-power rocketry, you might be tempted to skip the kit and use bulk black powder. But the pre-measured charges reduce error, which is critical when you're investing in a high-power rocket and motor. The small extra cost is worth the peace of mind.
Frequently Asked Questions
When should I use the ejection charge kit?
Use it whenever your high-power rocket relies on motor-ejected recovery. The pre-measured 1.4g charges are suitable for typical high-power rockets, but always check your rocket's recovery requirements and motor delay to ensure the charge is adequate. Confirm the charge size matches your rocket's needs before each flight.
How do I install the ejection charge?
Place the 1.4g charge into the EFC ejection charge holder, then insert the 1/2" ejection plug to secure it. Follow your motor's instructions for attaching the holder to the delay element. Ensure the charge is seated firmly but not compressed. Always do a dry fit before loading the charge to verify the plug fits correctly.
Are there any safety or legal requirements?
Yes. This product requires HAZMAT shipping via UPS or FedEx, and federal law prohibits sale to anyone under 18. The seller must receive proof of age (like a driver's license) before shipping. Always handle black powder charges with care, store them in a cool, dry place, and follow all local regulations. Have your ID ready when ordering, and store charges safely away from heat and flame.
