Cesaroni 38mm Reloadable Propellant Kits

Cesaroni (also known as CTI) is a manufacture of reloadable rocket motors, know as the Pro-X motors. The "X" is replaced by the engine diameter, so you can have Pro-29, Pro-38, etc.

These 38mm motors are made in the standard diameters, so they will fit into your current fleet of rockets without having to do any further modifications.

Start By Choosing Your 38mm Motor Type:

1-Grain
2-Grain
3-Grain
4-Grain
5-Grain
6-Grain
6-Grain-XL

How to Pick The Right Size Cesaroni Reloadable 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 - H )
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 Cesaroni 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 Cesaroni Case.

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

Cesaroni Propellant Types

Smoky Sam: Dense black smoke that obscures the flame.

White Thunder: Bright white flame, light gray smoke. Most realistic looking propellant.

Classic: Narrow orange flame, thin, light gray smoke.

Red Lightning: Red flame, white smoke.

Blue Streak: Blue flame, thin gray smoke.

Skidmark: Intense orange flame, thick black smoke with sparks (called a "Sparky" motor).

Imax: Initial greenish flame that turns orange before burnout.

Green: Green flame.

Vmax: Orange flame.

Why HazMat Shipping Fees?

Even though they are not classified as explosives, all Cesaroni motors currently require shipment through a certified hazmat carrier (such as FedEx-Ground, or UPS-Ground). This is because the motors either contain more than 30-grams of propellant, or because they are not certified to be shipped through the US Postal Service.

Both carriers require the motors be marked as hazmat, and because of that, they charge a $25 per box hazmat fee. Unfortunately, we cannot do anything about this, even if you order just one single motor. Sorry, but the the per box fee is the same.

Because of this, it makes sense to order as many large motors as possible to leverage the Hazmat fee. You may ask your friends in your club if they would want to go in with you on your order to minimize the effect of the Hazmat fee.

The good news is that FedEx-Ground and UPS-Ground are quicker shipping boxes to you than is the government. And it is far easier to track it trough the system from our dock to your front porch.

When you order these motors, you will be charged one Hazmat fee per box. Most boxes can fit 6 motors in them, although in the shorter sizes we can fit more. If additional HazMat fees are required, you will be contacted by our staff. If you have any questions, you are welcome to call us at: 719-535-9335.

NOTE: We cannot ship HAZMAT outside of the United States, to Hawaii, Alaska, or any US Protectorate.

Frequently Asked Questions:

Q. How do I adjust the ejection charge delay on the Cesaroni motors.

A. You need a special drill tool, called the "Pro-DAT" that allows you to put a hole into the delay grain that makes the coasting time shorter. One delay tool can be used on all 38mm motors. Click Here for more information.

Q. How do I remove the ejection charge on the Cesaroni motors?

A. This is the answer from Cessaroni: "The plastic white cap on the top of the motor is just tacked in place with some ABS glue (yellow). Just use a screwdriver or awl to remove it and then tap the powder out. No need to close it off again. But if you want to prevent any flashback from the delay through the touch-hole the user can just put a drop of epoxy in it or tape it." Note (legal disclaimer): Apogee Components is not responsible for the preformance of the motors nor any modifications you may make to them.

Q. How come the Cesaroni motors are non-refundable?

A. We would love to be able to say the motors are returnable and refundable, but the motors must be shipped as HAZMAT. It is possible to return them to us, but you do have to go through the training classes from the DOT (U.S. Department of Transportation) in order to qualify as a shipper of hazardous materials. Unfortunately, it isn't likely that you'll be able to take them to UPS or FedEx and have them accept the package from you unless you've completed the classes for Hazmat items. Therefore, please make sure that the motors you order will be correct for your project. Additionally, don't buy the motors for someone else and expect to ship them yourself (such as shipping internationally).
