The most expensive portion of a "single-use" composite-propellant rocket motor is the labor required to assemble it. Qualified technicians who assemble rocket motors don't come cheap. With a "reloadable" rocket engine, you provide the labor to assemble it.
Another expense in a single-use motor is the phenolic-plastic case that holds the propellant. Every time you fly a single-use motor, you have to get a new phenolic case too. Doesn't it make sense that if you use the case over and over that you'll rid yourself of that redundant expense? That's two ways you'll save money by using reloadable motors.
Here is the conclusion: the more times you reuse the reloadable motor, the more money you save! Tip: To calculate how much money you'll save with reloadable motors, see the Q&A article in Peak-of-Flight Ezine Newsletter issue #189.
In fact, most high-power rockets are flown with reloadable motors because the cost savings is so significant. You can start saving money too, even with mid-power size rocket engines.
Besides saving you money, the motors we offer have other advantages:
- They are legal in all 50 states and USA Territories!
- No Federal nor State Explosive Permits needed to possess or transport these motors.
- No "explosive storage magazine" required to store these motors in your house.
- We can ship them via the US Postal Service: That means there are NO expensive ($20) HAZMAT shipping fees!
