3 reviews for 001593 – 1/2A6-2 Engines

  1. Shane

    Good “maiden flight” engine

    I the 1/2A6-2 motor with my Hi-Flier and have gotten 94 flights from that rocket. I have made a few repairs along the way, but that motor has always kept that rocket within easy recovery range. Definitely use this motor the first time you fly a Standard motor rocket.

  2. alex

    good for light rockets/small fields

    For rockets that are light enough to use these they are great to keep the rocket at a manageable altitude to recover it easily.

  3. dave

    strong and reliable

    estes engines are easy to use work well and are reliable.
