Modifying The Sky Launch Controller for Bigger Batteries 

This 36" X 36" Reusable Nomex® parachute protector is for large rockets that are up to 12 inches in diameter. Nomex products last longer than other comparable flame resistant products. They can also be washed at home or by dry cleaning. The flame resistant properties of Nomex products are not removed by washing.

The 54mm Fly-Away Rail Guide can be used to launch those 54mm diameter rockets that do not have a rail button or rail guide. The advantage of removing the rail buttons is that it reduces the drag of the rocket and allows it to soar higher. Package contains one set of rail guides that will fit on a 54mm (thick-wall tube) rocket.

This clear polycarbonate tube makes a great payload bay, because you can see what is on the inside of the rocket. Compatible with Estes BT-70 tubes and nose cones. The perfect size to carry a raw hen's egg.

The Estes 18mm engine retainers are used to prevent rocket engines from sliding rearward out of the rocket. The advantage is they are cheaper in price than aluminum retainers, and that will save you money for your other projects. Now you can make your low power rockets look like they are high-power!

Nylon shear pins are used to temporarily hold sections of the rocket together until the ejection charge within the rocket blows them apart. They are often needed on high power rockets because the sections can separate prematurely due to the air pressure differences within the rocket. This is a larger size shear pin for those wanting to fly bigger high-power rockets.

Apple Macintosh users, we now have a version of RockSim that runs on the new 64-Bit Catalina OS. You can download it using the link you received when you purchased RockSim, or download the free trial version when you are ready to install on Catalina. This was the only change to the program - no other changes were made. Windows users: you do not need to do anything!

Are you looking for a bulk pack of rocket kits for your classroom where each rocket is different looking?

The Maker's Dozen rocket bulk-pack does just that - 13 unique rockets! Even though all the fins are different shapes, they each have the same surface area and the same span. This allows all the rockets to be compared to each other based on their flight performance. So fly them against one another to see who’s rocket can go the highest or the fastest. But be ready for some fantastic altitudes, as each of the rockets in the Maker’s Dozen can easily go over 1,300 feet in the air on a C6-5 rocket motor.
