A8-3 )? Can they be substituted?** A: When you are looking at the name of a rocket motor, there are really 3 things that the name tells you. First, the letter determines the total impulse of the motor (AKA the total energy release). Pretty much, an A class motor will have a total impulse of 0-2.4 Newton seconds of impulse, a B will have 2.5-4.9, and a C will have 5-9.9. This continues indefinitely as motor power increases. The number immediately after the first letter is the average thrust of the motor during the burn duration. In this case, the C6-4 will produce an average of 6 newtons of thrust, while the A8-3 will produce about 8 newtons. The thing is that, while the A8 produces more power, the C6-4 will burn much longer since it contains more fuel. Pretty much, the higher the number, the lower the burn time. Finally, the number after the hyphen is the delay before the ejection charge is deployed. For small rockets like these, you don't need the charges to be perfect, so anything between 3 and 5 seconds will usually be fine. However, if you are building a larger rocket, like F class or above, it is a good idea to do some calculations to estimate when the charge should fire, or you should use an electronic deployment system. **Q: do all 3 packs of engines a-3 thruc-7 comre with wadding and igniters plugs?** A: Just plugs and igniters **Q: What is the size?** A: Go to Estes website. Everything you'll want to know is there. **Q: What do these other reviews mean when they say they lost their rocket? We think this engine burned ours up. Is that a possibility?** A: The bigger the engine the higher the flight altitude and the likelihood of not being able to find the rocket when it lands (i.e. lost). The engines get hot but I have never seen one cause a fire or burn up a rocket. I would not launch one in dry brushfire conditions however. Other causes of loss are "cato" (crash landing) or landing in a tree (usually happens around here) - normally the tree species has the scientific name or "Rocketus Eatemupus" :-). Also I think a dog once found a rocket after it landed and ran off with it. Also a farmer ran over one with a plow. ## Frequently Bought Together - MDL RCKT ENGNS 3PC C6-5 - Estes 2274 Recovery Wadding - Estes 1491 Taser Rocket Launch Set, Beginner Flying-Rocket-Model Building Kit for Ages 10+, Includes Launch Pad System --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/780078143-estes-c6-5-model-rocket-engine-3-pk-by-estes](https://www.desertcart.pl/products/780078143-estes-c6-5-model-rocket-engine-3-pk-by-estes) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-30*
