Astra 1

Astra 1

Hobby rocketry leader Estes Industries makes more than a dozen inexpensive launch sets (launch pad/rod, launch controller) for beginners, but their included rockets are either pre-built or not much of a challenge.

ArduCopter 3DR Quadcopter

Quadcopters rely on computer stabilization to fly. They can be radio controlled, but with an onboard computer, why not let it fly itself?

The ArduCopter 3DR Quad Kit […]

The kit has everything you […]

Medieval Battering Ram
