    Do You Need Help Choosing A Rocket Motor?

    Don't panic! We're here to help you.

    1. First off, take a look at your kit. Are there recommendations on the packaging?
    2. If you purchased the kit from us, or if you purchased a kit that we also sell, take a look at the recommendations on the kit's page. It's near the bottom.
    3. If your field is limited and surrounded by trees and buildings, choose a motor with a lower letter and number to limit altitude and increase your chance of recovery.

    If you're still unsure about which motor to use, don't hesitate to call us at 719-535-9335 and ask for our recommendations. We're warm and friendly, and don't bite (that's a promise).

     

    What is a "Single-Use" Motor and Why Should I Use One?

    The motors listed on this page are all "Single Use," which means they can only be used once and then the entire thing, casing and all, is discarded. We also offer "reloadable motors" in which the casing can be cleaned out and used over and over.

    What are the advantages of single-use motors?

    1. They are simple and reliable. Just put the motor into the rocket and launch it!
    2. They're readily available and, in an emergency, you can pick some brands up at local hobby shops.
    3. Fastest turn-around times between flights of the same rocket means you can get a ton of flights done in the same day!
    4. If you lose your rocket due to wind, extreme altitude or other, you're not out the investment of the much more expensive reloadable casing.
    5. Safer to use by younger children, as the propellant and ejection charge are all sealed within the casing.

    What is the disadvantage of single-use motors?

    1. Single-use motors cost a little more per-flight than reloadable.
    2. Larger single use motors, particularly with E class or higher, you often have to pay a HAZMAT fee, which can cause shipping to be upwards of $45. This is because only so much propellant can be in a continuous chunk before there is an assumed risk. Any motors that require the fee are marked.

    You have to weigh the advantages versus the extra cost. We believe that there are a lot of cases where it makes sense to use them, which is why we carry so many different ones.

     

    What do all the letters and numbers in the the motor name mean?

    Lets take an example so you can see how to read the charts. As an example, we'll look at the "B6-4" motor. 

    Breaking it down, we have four bits of information. "B," "6," and "4"

    Power ClassificationThe first letter, "B," in our example, is the power level classification of the motor.  The "B" power band, as the chart to the right shows, is greater than 2.5 Newton-seconds of Total Impulse, and less than 5 Newton-Seconds. The maximum power doubles from one letter to the next. So a "B" motor can have twice the power of a "A" motor; which means it will fly approximately twice as high.

    Remember, think of power as the size of the fuel tank. The tank doesn't have to be totally full. So An "E" motor isn't required to have the maximum of 40 N-s of total power to still be classified as an "E". It just has to have greater than 20 N-s but less than 40 N-s. This gives us the power-bands (shown as the colors in the chart to the right).

    The first number after the power letter is the average thrust level of the rocket measured in Newtons, equivalent to 0.225 pounds of force. That means in our example, the motor has an average thrust of 6 Newtons during the entire burn time. If you were driving a car, you could relate average thrust to the amount of pressure you push on the accelerator pedal. The harder you push, the higher the average thrust of the motor, and hence the higher you'll accelerate the rocket. If you want to go fast, choose a high thrust motor. If you want to get good economy (longer travel distance), choose a lower average thrust motor. 

    For example, a B6 and a B4 would have the same amount of fuel in the tank. But the B6 burns it faster, and hence the rocket will reach a higher speed. The B4 motor burns the fuel slower, and like in your automobile, you'll get more distance out of the fuel that is burne

    The number after the dash is the length of time in which the "delay" charge burns before it allows the ejection charge, which deploys your parachute, to go off. Delay allows time for the rocket to coast and slow down so the parachute doesn't rip out of the tube at ejection. In our example, the rocket would coast for 4 seconds before deployment.

    Most single-use motors give a hard number for the delay, and you will need to purchase the appropriate one for your kit. Some loadable, larger single use or reloadable motors will often have a maximum delay that, with a specially designed tool, you can use to shorten the delay to what is best for your rocket. Look at the "Max Delay" statistic for that particular motor.  If it is an N/A, or not listed, you cannot adjust the delay.

    Engine Diameter and Length

    Unfortunately, the engine diameter and length are not included in the type code printed on the side of the rocket. So before you can pick an engine from the charts, you have to refer back to the rocket kit itself, and see which engine diameter it can use. Do that first. Most kits can accept different length motors, so that is not an issue. The most important thing when selecting a rocket engine is the diameter, and then the "type" designation.

    Frequently Asked Questions


    Q: Why don't you ship rocket motors to countries outside the USA?
    A: There are too many shipping regulations. We're a small company, and we don't have the manpower to track the regulations for each country in the world. So to keep our prices as low as possible, we only ship to USA customers.

    Q: Will the Aerotech First Fire Jr.™ igniters work in these motors?
    A: NO. They are too big to fit into the nozzle hole. They are better for bigger size motors. The Estes Sonic or the Quest Q2G2 are best for replacing any lost or fizzled igniters.

    Q: Can you ship this item to me by this weekend?
    A: All motors (including kits that contain rocket motors) must be shipped by surface transportation (truck). While we usually ship this item the same day the order comes in, you should plan extra time for the postal service to deliver them via third class mail (Parcel Select).

    To expedite your order, you can request that the order be split, and the motors ship separately from the rest. This will incur a fee of $6 for standard motor shipping (not hazmat) to cover the additional cost of two shipments.

    Q: How do you find the Maximum Weight a rocket motor can lift?
    A: Click Here to read the article that explains how "Manufacturer's Recommend Lift-Off Weight" is determined.

    Q: How is maximum lift-off weight determined?
    A: The maximum recommended lift-off weight for each delay depends on the size of the rocket, its drag coefficient, launch angle, and the wind conditions at launch. We recommend running a RockSim computer simulation for each rocket design and launch conditions to select the proper motor delay. For help selecting the correct delay time, see Apogee Technical Publication #28. For additional information on maximum lift-off weight, see our FREE newsletter article on this subject. Click here to download Issue #214.

    Q: I have some old Quest motors, and they have these funny looking igniters in the package. How do you ignite the motor with them?
    A: These are called Tiger Tail igniters, and they are similar to the Aerotech Copperhead igniters.

    Q: What are the little red tubes for in the picture above?
    A: They are little plastic tubes. You deform them and shove them into the nozzle to hold the igniter in place.
