Yes, you're right it is a quite interesting contraption! It is true that there is not much to see on the outside. The frame is 2 inch aluminum pipe bent and welded, with a fiberglass backpack and funny looking wheels. The controls are direct, like many gyrocopters. In front of the pilot attached to the control bar is the control panel with the throttle (altitude control), tachometer, ignition power, starter and yaw switches. The tools necessary for flight do not seem like much because they aren't. This is not only the lightest helicopter in the world, but it is the easiest to fly!
