The brand new v2.2 launcher is here!
Here are the updated instructions:
Cut open sleeve around box. This latest batch had some VERY tight fitting sleeves, so you need to cut them off. Carefully cut along the side of the sleeve. Cutting along the same side where the box opens is easiest, as the knife will follow the edge.
Open the box. One of the long sides of the box opens like this:
Open and read welcome letter, and check out the paper templates.
Remove all kit contents and arrange neatly (technically known as knolling):
Start assembling! Start by applying pipe tape from the blue roll around the large end of the brass schrader valve. If you wrap it in the direction shown, it is much less likely to push out of the way when you thread it into the mating part.
Thread the Schrader Valve into the Slide Valve.
Tighten the Schrader Valve into the Slide Valve using two adjustable wrenches, or an adjustable wrench and a 9/16″ wrench.
Wrap pipe tape around male threads on end of the tank. 3 or 4 wraps should be adequate.
Thread the tank into the QEV (Quick Exhaust Valve). Note laser marked ports.
Tighten the tank. Hold the QEV down while you use an adjustable wrench on the flats at the far end of the tank to tighten it. Get the adjustable jaws tight on the flats. No need to make this too tight, the wrench flats are not that large.
Wrap pipe tape on Inlet Fitting. While this fitting already has sealant applied, it is OK to wrap pipe tape over it.
If a spring is provided in the kit, (in the latest kits) nest it within the fitting, and compress it as you start the threads.
Install and tighten inlet fitting. Again, no need to make this super tight. The plastic section can rotate on the metal part, allowing you to align the tube outlet.
Wrap pipe tape on the threads of the over pressure valve.
Tighten the over pressure valve into the end of the aluminum tank
Install launch tube hand-tight. No need for pipe tape here. If there is a leak, it won’t matter.
Assemble the wooden base by aligning and interlocking the wooden base parts as shown. Note the oblong hole aligns with the side with the shallow grooves.
This is a tight fit, so flip the base over and use your body weight to fully seat the parts together.
Slide the tank into place.
Install the tank until the side of the QEV touches the wood base.
Install the U-Bolt.
Install the two washers and the two wing nuts.
Push one end of the tubing into the inlet fitting. It should engage by about 1/4″ (6mm).
Push the other end of the tube into the slide valve. It should engage by about 1/4″ (6mm).
Your Compressed Air Rocket Launcher is Complete!
Storage and Transport:
To make the launcher more compact for transport and storage, the launch tube can be unscrewed and stowed in the base. Slide the launch tube into the lower slot and secure with the provided velcro strap. The upper storage location can hold a 3/8″ NPT launch tube (not supplied) if you want to launch smaller diameter rockets (such as stomp rocket brand) or our original version of the Air Rocket Glider (ARG).
Coil the tube around the notches in the base.
Launcher is complete!

Operation and Launching:
First, connect your pump to the Schrader adapter attached to the slide valve. Start with a test firing of the launcher without a rocket. With the blue part of the slide valve in the launch position, there is no pressure within the launcher. Now move the blue part of the slide valve to the Pressurize position (shown in the photo below), and pressurize the chamber by pumping. If you hear a slight hiss or a quick pop, that is the overpressure valve doing its job as you have exceeded 130 PSI. This is normal. When you are ready to launch, stand back, give a countdown, and slide the blue part of the slide valve away from the launcher to the LAUNCH! Position quickly. You should hear a loud “Pop” of air as the pressure in the tank is quickly released.
Once you have ensured the launcher is working properly, it’s time to launch the first rocket. With the slide valve still in the “Launch” position from the test firing, there is no pressure in the launcher. Load the paper rocket onto the launch tube. It should be a slight friction fit for the best performance – too tight will turn your rocket to confetti, too loose hurts performance. Now move the blue part of the slide valve to the “Pressurize” position and pump to pressurize the tank. When you have reached your desired launch pressure (usually between 30-120 PSI), stand back, do a countdown, and launch your rocket by quickly sliding the blue part of the slide valve to the “Launch” position.
