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!
