Estes is the company that began model rocketry back in the 1960's. They have designed solid-fuel engines that are reliable and easy to use. The engines (motors) are simply standardized cylinders filled with varying amounts of solid rocket propellant.

Each rocket engine is characterized by a number on the engine. For example, in the C6-5 engine, the "C" stands for total impulse power (measured in Newton/seconds). There are Estes engines in size A, B, C, D, and E. A, B, and C engines are all of the same size and can for the most part be used in all standard model rockets. "D" engines are larger and wider and cannot be used in standard model rockets. "E" engines are the largest engines Estes produces and are available only to those over the age of 18. They are used to launch much larger and heavier rockets.
The important thing to know is that as you advance from one letter to the next, the thrust increases by 2 power. So a "B" engine is twice as powerful as an "A" engine. A "C" engine is twice as powerful as a "B", and so on.

The next number refers to the thrust power. The higher the number, the higher the thrust and the faster the rocket will go.

The final number is the time delay factor. In the C6-7, the 7 refers to the approximate amount of time in seconds from ignition to when the engine expels the gas that expels the parachute. (The "7" denotes the delay factor).

Rocket engines should be selected according to the size of a rocket, the weight of the rocket, and the amount of land area you launch in. If you have a very small recovery field, then stick to smaller engines, such as A's and B's. You won't lose your rockets to wind drift as they won't go that high. However, if you have a large recovery field, the sky is really the limit, as you can use the most powerful engines in even small rockets to give maximum altitude. I have lost more than a few rockets by launching a relatively small rocket with a C6-7 engine, never to see the rocket again. It simply went out of sight and was carried away by the wind.

The engines come with a set of ignitors which in turn are set off by a launch control system.

Estes engines are almost 100% reliable. I have only seen a few fail in all my many years of model rocketry.

These are $6-8 at most places, go to ehobbies dot com and get them, or a whole flight pack (24 engines) for $43.

Get a 3-pack of C6-5's for $6 at WalMart, folks! Pay a little tax, but no shipping charge!
