Reviews : Estes C6-5 Model Rocket Engines (3)

This is a good 18mm engine. It is quite powerful, and I love the long burn time, and the jump off the pad it gives lighter rockets. It'll get an Alpha or similar rocket way up there! The only problem is that sometimes it is too powerful, and I have lost 1 rocket, and had 3 or 4 rockets damaged as a result of not so perfect recoveries.

My favorite engine in this size - launches small to mid sized rockets really well with great altitude. This is my go to engine for all my single stage rockets up to 2 diameter x 30 tall. This engine will send a small rocket out of sight in a hurry.

This rocket engines work amazingly. Its a powerful engine that sounds great.Very reliable Iv probably launched off this engine 50+ never has failed me. This engine is worth buying.

these are great motors great for beginners and great for seniors there great for high flieing and lots of other thing its great to have these laying around for my hobies

These motors worked excellent in my rockets. They went about 500' in the air and sounded like actual rockets. There fun to shoot off.

We use these often. It's our favorite for a small to mid-sized field for the Estes Firestorm and Shooting Star.

Never fail, light weight with lots of power! I use these as my baseline motors

Good engine I launched many rockets with this. Really gets them off the pad

Great motor for extra height. It works best with lighter weight rockets.

My go-to 18mm motor! Sends the classic super high with a long burn!

Great engines, low price and fast shipping. Can't wait to use them

They have the beat altitude of the lower stage rockets
