One downside of the quad-rotor design is the need for large airframe support arms that connect the rotors and cockpit. These airframe truss arms need to react large bending moments but be as lightweight as possible.

For Gamera II, innovative micro-truss structures were employed to greatly reduce airframe weight.

Originally developed for Gamera I, an even lighter version was designed for Gamera II, and more extensively employed.

The result was a 39% reduction in weight over Gamera I, an incredible 12.5 lbs!
