Want a cheap rocket that can survive super sonic speeds (Mach 1, the speed of sound, is approximately 761 mph at sea level)? The Apogee Aspire is a prefect rocket for this task. It is minimum diameter for 29mm diameter high-thrust rocket engines, and it has a sleek shape that is just made for cutting quickly through the air. In this publication, you'll be shown you how to take the stock Apogee Aspire kit, and with a few simple modifications turn it into a supersonic cruising model. How? You don’t...

The purpose of a piston launcher is to provide an extra kick to the rocket as it takes off. It does this by collecting the exhaust gases from the rocket engine inside a tube. As the gases build up, the pressure inside the tube increases and kicks the rocket off the pad with a higher velocity. It is estimated that the altitude increase from this can be greater than 5%. That's not bad, since you don't need to change anything else with the rocket.
