Gamera consists of an X-shaped fuselage frame using a micro truss structure that helped reduce overall weight by 33% from the Gamera I. The transmission, cockpit and rotors have been refined from the original Gamera I. The transmission now includes a flywheel to reduce "jerky" impulses on the rotors.
213:
At the terminus of each end of the frame resides a rotor. Each rotor weighs 2 kg (4.4 lb), and the powerplant/pilot weighs 135 lb (61 kg) to 145 lb (66 kg). Power is transferred to the rotors via hand and foot pedals in a pod suspended beneath the structure. Up to 20%

developed the year prior. Two other teams have made
Sikorsky Prize attempts unsuccessfully. On June 13, 2013, the University of Toronto Team's AeroVelo Atlas, managed to keep its helicopter in the air for 64.11 seconds, reach a peak altitude of 3.3 meters and drift no more than 9.8 meters from the

November 2011. On June 20, 2012, Colin Gore flew the Gamera II at the Reckord Armory on the University of Maryland Campus for a duration of 35 seconds, setting a new world record for human powered helicopter flight duration. With engineering improvements, the team bested the

On August 28, 2012, Colin Gore powered the Gamera II for 65.1 seconds, within a 10-meter x 10-meter area. Two of the three criteria prescribed to meet the
American Helicopter Society Sikorsky Prize competition were achieved, with only hover height falling short. Sonar altimeters and a modified

On
September 25, 2013, pilot Justin Mauch powered Gamera IID (a modified version of Gamera II) for a certified U.S. record and pending world record flight duration of 97.5 seconds. On the same day, female pilot Kay Tsui set a new U.S. record for a flight duration of 38 seconds.

include achieving a flight duration of 60 seconds and reaching an "altitude" of 3 m (9 ft 10 in). At the same time the aircraft must prove that it is controllable by remaining within a 10 m (32 ft 10 in) square.

The rotor weight was reduced by 39% by reducing material in the webbing of the triangular truss spars that deflect only 1 ft versus 25 inches on Gamera I. The rotors are now tapered with a Selig S8037 airfoil and rigged with a 3°

Gluesenkamp flew the Gamera II for an unofficial world record of 50 seconds. The time will be submitted to the
