Estes C6-5 Model Rocket Engine 3/pk. by Estes

Worked great for our hobby rocket launches. Our rocket went really high! Will definitely get again. Good value, easy to use and fun to watch.

They work great, they’re very few places that carry rocket engines where I live so it was super convenient to order from Amazon and the prices are reasonable

All 3 worked flawlessly.

This was the package needed to fly my grandsons rockets. It came with the starters and plugs.

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!)
