Engines purchased in March 2025 failed.

The engines were a dud and failed to ignite.

I love ESTES!!!

I love Estes Rockets, I have loved them since my first one when I was like 10 years old. I have had many throughout my life and now I get to share the experience with my daughter and son. Our first 2 from this purchase we launched with the C6-5 motors and lost both :)

All good though, part of the rocketry experience. These are very powerful motors.
