Cesaroni Pro-29 Reloadable Motor Hardware Cesaroni (also known as CTI) is a manufacturer of reloadable rocket motors. These 29mm diameter motor cases allow you to take an existing 29mm rocket and put an F to an I-class motor in it. Since an H-size motor is the first high power motor, you can get your Level 1 certification using a sturdy-built existing kit! These 29mm casing are very popular for that very reason. The other advantage of 29mm motors is that 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?

How to Pick Your 29mm Cesaroni Motor

More Information About Cesaroni PRO-29 Reloadable Motor Casings

Pro29® rocket motor hardware is as simple as you can get. With the forward closure included in the reload kit, you only need your motor case of choice and one rear closure. Manufactured from thin-wall 6061-T6 aluminum tubing with a clear anodized coating for corrosion protection, Pro29® motor cases are lightweight but strong, capable of holding well over 3000 psi of internal pressure. The forward closure is retained by a formed rim at the head end of the casing. The rear of the casing has precision-machined internal threads. Pro29® motor casings are available in seven sizes. Please refer to the motor specifications page to see which casing is required for each Pro29® reload. Don't forget that you'll need a delay adjustment tool for your Pro29® reloads, unless you use electronic ejection exclusively. The ProDAT-38® tool allows you to choose from 5 preset delay times with every reload

Do You Need A Different Diameter Reloadable Motor Casing?

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 ) - Coming Soon 29mm Dia. Motors (power: F - H ) - You're on the right page now! 38mm Dia. Motors (power: G - J ) 54mm Dia. Motors (power: I - K ) - Call to Special Order 75mm Dia. Motors (power: K - M ) - Call to Special Order 98mm Dia. Motors (power: K - N ) - Call to Special Order 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?

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 29mm and 38mm motors. Click Here for more information.

Q. Can I use Aerotech propellant in the Cesaroni cases? A. No. the sizes of the propellant are different and therefore the Pro29® motor cases are not compatible with any other brand of reload except Cesaroni. Q. Are there any special tools that are needed to assemble these motors? A. No. Assembly is simple. Q. Don't I need to be high-power certified to buy these motor casings? A. No. You can buy the aluminum casings without being certified. However, you do need to be high-power certified to buy the propellant kits (H size and larger). Q. Where do I go to get High Power Certified so I can buy the propellant kits? A. In the United States, there are two organizations that can certify you to fly high power motors. They are the National Association of Rocketry, and Tripoli Rocketry Association. If you are outside of the USA, please click here.

Q. If I leave the engine block and hook off the rocket, what keeps the rocket from sliding into the rocket? A. The lip on the back of the motor butts against the aft edge of the engine tube. This prevents the motor from sliding forward. Cool, isn't it? To prevent it from sliding aft, you can put a layer of tape over the top. Click here for more information. Or you can use an engine retainer shown below.

Q. What kind of hook should I use to hold the 29mm reloadable engines in my rocket? I noticed that the Apogee web site doesn't have long engine hooks. A. Aero Pack Engine Retainers. These are useful on rockets that use the 29mm diameter reloadable motors.

Rouse-Tech Motor Cases - The Rouse-Tech motor casings use the Aerotech reloads kits. They are an alternative to the Cesaroni motors, and come in the same diameters so you can use them in your already-built rocket fleet. Why buy from Apogee?
