The copter was in Carbon-Fiber and Aluminium... 6 Servos, Alcohol & Nitro-Methane fuel powered (making it much more efficient than a regular gasoline engine). At a peak RPM of 18,000, watch the blades ! This particular model can reach 70 mph in speed (without diving first), weighs just under 5 kg and can lift an extra 2 kg (not enough for Anoushka, as she now weighs 4.95 kg).
