The 54mm motors are the bread-and-butter high-power (level 2) motors, and they still come with delay and ejection charges. You do not need to invest in electronics and other equipment to pop the parachute out of the rocket. This fact simplifies construction of the rocket and makes it easier to gain experience with building high-power engines. When you first get into high power rocketry, you'll probably want to focus all you attention on building the rocket strong enough to handle the higher forces that occur with big rockets. You don't want to worry about getting the electronics to work properly too, do you? Just one step at a time, right?

Optional Accessories For 54mm Reload Hardware
Description	P/N	Price	Place Order Now	Comments	Image
54mm Standard Forward Closure	60140	$39.95		It is used on motors where you need the ejection charge to pop the parachute out of the rocket. This is the standard forward closure that comes on all 54mm hardware sets. You only need to order it if you lose yours.
54mm Plugged Forward Closure	60141	$39.95		It plugs the motor. Use only if you decide to use electronics (like a timer or altimeter) to control the ejection of the parachute, and you don't want the motor to control ejection.
54mm Tapped Forward Closure	60145	$54.99		Tapped (threaded) nipple on end of closure. It not only plugs the motor, but you can screw an eye-bolt into the threaded end to attach the shock cord right to the motor. Note: Eyebolt is not included. Used only if you decide to use electronics (like a timer or altimeter) to control the ejection of the parachute, and you don't want the motor to control ejection.
54mm Standard Extended Forward Closure	60142	$41.99		Use on selected long-burn motors (see table above). It is used on motors where you need the ejection charge to pop the parachute out of the rocket.
54mm Extended Plugged Forward Closure	60143	$41.99		Use on selected long-burn motors (see table above). It plugs the motor. Use only if you decide to use electronics (like a timer or altimeter) to control the ejection of the parachute, and you don't want the motor to control ejection.
54mm Extended Tapped Forward Closure	60144	$57.99		Use on selected long-burn motors (see table above). Tapped (threaded) nipple on end of closure. It not only plugs the motor, but you can screw an eye-bolt into the threaded end to attach the shock cord right to the motor. Note: Eyebolt is not included. Used only if you decide to use electronics (like a timer or altimeter) to control the ejection of the parachute, and you don't want the motor to control ejection.
54mm Forward Seal Disk	60102	$14.99		Use only on the longest casing: RMS 24/2560. Your hardware set will include the forward seal disk. You only need to order this item if you should happen to lose yours.
54mm Aft Closure	60149	$41.95		Your hardware set will include the aft closure. You only need to order this item if you should happen to lose yours.

More Information About Reloadable Motor Casings

The aircraft-grade aluminum reload hardware consists of three parts: the case, the foward closure and the aft closure. Here is what each is used for: The case holds the propellant inside. It is anodized yellow to make it easy to find if it ever should fall to the ground.

The forward closure screws onto the front end of the case. It serves multiple purposes. First, it holds the hot gases of the burning propellant and keeps them from shooting forward into the body of the model rocket. It also holds the special slug of propellant called the "delay grain." Finally, it has a small receptical at the tip to hold the black-powder ejection charge. The aft closure screws onto the base of the aluminum case. Like the forward closure, it is a bulkhead that holds the hot gases inside the case so the motor can produce thrust. In the middle of the part there is a big hole, which allows the nozzle to protrude out the back end of the assembly. Their is another feature of the aft closure that makes it convenient for use in most rockets. The diameter is bigger than the case. When you push the motor into the engine tube of the rocket kit, it stops when it butts up against the aft closure. In effect, it acts as the engine block. This way you can leave the engine block out of the kit if you want to use it with different length reload motors!

The longest case (from RMS-54/2560) also comes with a forward seal disk. This disk is inserted into the front end of the propellant liner and prevents the forward end of the case from discoloring and blistering from the intense heat of the bigger motors.

Made in the USA by Rouse-Tech, these are precision engineered cases that are designed to be used with the Aerotech propellant kits.

In fact, theses cases have the exact same specs as the one from Aerotech, because Aerotech licensed Rouse-Tech to make them for consumers. The only difference is the anodized color on the outside of the motor.

Step 1: Pick the diameter of the engine. Clicking on the diameter will take you to more information about each diameter motor so you can select the correct casing. 24mm Dia. Motors (power: E - F ) 29mm Dia. Motors (power: F - G ) 29mm HPR Motor (Power: G - I ) 38mm Dia. Motors (power: G - J ) 54mm Dia. Motors (power: I - K ) 75mm Dia. Motors (power: K - M ) 98mm Dia. Motors (power: K - N ) Step 2: Pick the Aerotech Propellant kit that you want to fly in your rocket. To be honest, this is the most time-consuming step. Contact us if you need help. We'll direct you to the RockSim software that we use to help pick the right rocket engines for your vehicle. Technical Publication #28 gives you a step-by-step procedure for picking the motors that might work in your rocket. Step 3: Match the propellant kit that you just selected in step 2 to the appropriate Rouse-Tech Monster Motor Case.

The aluminum reloadable casing is also called the "reload hardware." Why not let Apogee Components be your hardware store?

Q. How easy is it to assemble a reloadable rocket motor? A. It will take you about 5 minutes to put one together. If you want to see how easy it is, watch our YouTube video where we put one together (click here).

Cesaroni Reloadable Rocket Motors Cesaroni (also known as CTI) is a manufacture of reloadable rocket motors. These motors are made in the standard diameters, so they will fit into your current fleet of rockets without having to do any further modifications. Note: the cases are not compatible with Aerotech Reload Propellant. 29mm Dia. Motors (power: F - I ) 38mm Dia. Motors (power: G - J )
