L3 Bird

I’m building a pre-release of the GLR Sledgehammer for my Level 3 Certification flight. Giant Leap makes great rocket kits (I got my L2 certification and broke Mach with their minimum diameter Firestorm54) , and this latest project is no exception.


I will be using some new materials for the wings and fins – a strong but light aerospace composite with NOMEX honeycomb sandwiched between G10 fiberglass. It also has an elegant cluster of three avionics bays for redundant flight computers, GPS and RF transmitter.


With an M-size motor (imagine four thousand Estes A engines), RockSim estimates that the 7.5 ft. tall, 43 lb. rocket will pull 20 g’s.


I am hoping to launch it at Rocket Mavericks in July if not sooner.
