Great performace for smaller rockets and small fields and first timers.

Great engines!
These are nice simple engines for a starter and will launch your rocket a good 500-700 feet

gets rockets high enough to be exciting
A8-3’s are the “go to” engines for first flights. Excellent for checking a newly built rockets flight characteristics or to help get a gauge on which way and how far the wind will carry the rockets at recovery. They are also good to get the rocket up high enough for an exciting flight, yet still be recoverable inside a moderately sized field (like a football field).

Good standard engines
These are useful engines recommended by Estes for the first flight of most rockets requiring standard engines, both for safety and to get used to the flight path of your rocket.

Great Maiden Flight Engine
This is a great first flight engine! Gets the rocket off the pad quickly, yet burns out quickly enough to keep the light and medium rockets within sight. Buying these in bulk save on multiple rocket model maiden launches which can quickly be upgraded to its max engine on a clear no-wind day.

Perfect for test flights
If you want to test your new rockets to see how they fly, starting with this A engine is a good bet. It will let you know if you need to make any minor adjustments prior to launching B or even C engines. ESTES NOTE: As long as the A8-3 engine is a recommended engine.

A8-3 Engines
Good little engine for when you don’t have a lot of open space or the wind is strong. Good starter engine for young rocketeers.

Best for first timers
I’ve counted this engine blasts for about 4 seconds before the parachute ejects, really really short distance but perfect for first timers, or to give you an idea of the trajectory if you’re using a bigger engine for 2nd launch. On one windless day the rocket lands no more than 6 feet from the launch pad, pretty impressive!

Great for smaller rockets!
On days when there’s a slight breeze and don’t want to risk losing a lightweight rocket, this is the perfect engine. Great delay for its power, too.
