Quest Economy Rocket Motors

Want to learn how model rocket engines work?
Click here.

Quest Aerospace makes a reliable rocket motor that is great for most rocket kits. They are particularly great if you are on a tight budget!

These are an easy-to-ignite black-powder propellant rocket engine. They are all the standard 18mm diameter motors that are 2-3/4 inches long - which are the same size as the "regular-size" Estes rocket engines. The big difference is that they are lower in price. They will loft your rockets just as high, and just as fast as the Estes motors. Since they are black powder, they produce lots of thick, puffy grey smoke - making them easy to follow up into the air.

All the motors come three to a package. They the new
Quest Q2 igniters, which can be purchased separately.

Need to convert your kit to fit a smaller diameter motor?
Check out all of the Apogee Motor Mount Kits!

We also stock the "value" packs of motors, which come in packages of 25. These value packs are great for schools, scouts and youth groups, because it really knocks down the
price per flight.

Please be aware that typical shipping transit times for motors are 1-2 weeks.

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. Can you ship motors to me by this weekend?

A. All rocket motors must be shipped by surface transportation (truck). While we ship the motors usually the same day the order comes in, you should plan extra time for the postal service to deliver them via third class mail (Parcel Post).

Q. Which igniters should I buy if I want spares for these motors listed on this page?

A. Get the Quest "Q2" ingiters. Click Here for more information.
Quest igniters

Q. What is Recovery Wadding, and why do I need it?

A. Click Here for more information about Recovery Wadding. Note: The packages of Quest motors listed here on this page do contain a small amount of wadding.
Recovery Wadding

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.

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. Just watch our short video (click here) on the installation precautions of the Tiger Tail igniter. This will insure successful operation of the motor.
