The F10-4 is part of the Apogee Components "Medalist" line of rocket motors. It features ultra-high-energy propellant (very similar to what is used in the Space Shuttle) and is designed for a special application: lifting lightweight rockets to extreme altitudes. This is a 29mm diameter motor, but is not designed for heavy rockets, like those from Aerotech Consumer Aerospace. It is a LONG burn motor, with a thrust duration of over 8 seconds; which is the longest burning hobby motor. This means it will go and go and go, and you'll wonder if it will ever stop. It also makes a unique sound as it burns, sort of like a hissing snake. You and your friends will be awed by high your rockets will go with this motor. This motor can push a lightweight rocket kit, like the Apogee Aspire rocket kit to over 1 mile high! It is not suitable in multi-stage rockets. Includes an igniter and instructions for use. Qty per package: 1 Due to government regulations, this model rocket motor must be transported by truck (no expedited aircraft transport) and cannot be shipped outside the USA. Please allow for extra delivery time when ordering. Always have an adult supervisor present when launching any model rocket.
