One of THE classic LOC designs, the Magnum is the perfect kit to make your Level 1 and Level 2 certification flight with. NOW REVISED to a single 54mm motor mount, a J350 motor achieves apogee at around 2200 ft using the optional MMA-4 38mm motor adapter. The Magnum 3E sports 3/8" fins, a 75mm motor mount, and an electronics bay with all recovery gear needed for dual deployment. Great for L3 attempts! Plus, both models now feature our LOC-N-Ring rings and fins--build the fin can outside the airframe for a rock solid foundation. This rocket should be in every collection!

    Kevin A. ★★★★★

    Went straight for the J350 motor for my Level 1 cert flight, and the kit handled it without a hitch—the single motor mount made assembly so much simpler than I expected. Apogee was right on target, and the whole build felt solid.

    Emily U. ★★★★★

    The single 54mm motor mount is a huge upgrade—it took my J350 without a fuss and the flight was textbook straight. Assembly took a couple of evenings, but the fit was clean and I’m already planning my next cert flight with it.

    Eli B. ★★★★★

    Flew this on a J350 for my L2 cert and the flight was textbook perfect, straight boost with a clean ejection right at apogee. The single 54mm mount made motor retention simple and the whole build was straightforward.
