## Description

desertcart.co.jp: Estes C6-5 Model Rocket Engine 3/pk. by Estes : Hobbies

Review: They work great, they’re very few places that carry rocket engines where I live so it was super convenient to order from desertcart and the prices are reasonable
Review: If you really want to lose your rocket... I recommend these engines, LOL. They are great fun for a calm day - get your cardio on, and be ready to squint to find your rocket in the sky when it gets to apex - these engines will take it there. Binoculars are a good idea. If you want, you can weigh your rocket down a bit - but where's the fun in that? If you want shorter run distance, or a better chance of seeing the payload eject to follow the parachute, use smaller engines. :) For the price, if you only use 1, that's no good - so definitely use in a larger rocket spec'd for these babies and go recover it for launch after launch of fun! Worth every penny to see the faces on the ones who came back from chasing the rocket down! (hack/wheeze, LOL!)

## Questions & Answers

**Q: What are the differences between this and other engine packs ( eg. 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.

You'll receive a fresh stock of engines in a estes factory bag instead of a retail cardboard hanging card as shown in the photos, but it doesn't matter because the engines are dry and work great.
