BALLS 17, the premiere experimental rocketry launch contest, has been announced for Sept 26, 27, 28 in Black Rock, Nevada. The event website has details on BALLS 17 and the competition rules.
This is the extreme rocketry event where experimental rocketeers push the envelope of size, staging/clustering, altitude, home-made components and motors, and cutting-edge rocket tech. Not for the faint of heart and not for children. Bring your hard hat.
