Product Details

The finest rocket engines available!

All engines include complete operating instructions. Here’s a guide to help you choose the engines you need:
  1. The first letter stands for the relative power of the engine. The “B” engine is twice as powerful as the “A” while the “C” is twice as powerful as the “B.”
  2. The first number following the letter indicates the engine’s average thrust in newtons.
  3. The number after the hyphen is the number of seconds between the end of thrusting and the start of the ejection charge. This double charge occurs because the engines fire in two directions—at launch and then in the opposite direction to eject the streamer or parachute or to fire the second stage of the rocket.
For example: A C6-5 engine is the most powerful engine we sell. It has an average thrust of 6 newtons and has a five-second delay before the ejection charge, or second stage, is ignited.

Regular engine packs include three or four engines, igniters and igniter plugs. Our economical Bulk Packs include 24 engines, igniters, igniter plugs and recovery wadding.
