  1. Outstanding Level 3 Rocket!

    Posted by Shane on 9th Nov 2018

    I built the DX3 Massive and launched it in October, 2013, when it was a new kit. The fiberglass components are top quality and fit together perfectly. You can not go wrong with this kit! It is rugged, well-designed, and will last you years of flights. I can not recommend Madcow kits highly enough.
    My first flight of this rocket was my Level 3 certification flight- You can see that flight on YouTube- search for Shane's Level 3 Certification and you will see just what a beautiful flying rocket the Madcow DX3 Massive is.
