Model representing the CL-227 drone designed by Canadair in 1977. This is a non-commercial 1:16 scale model. The first tests of the remotely operated vehicle took place at the military base in Suffield, Alberta, in 1981. The CL-227 is an unmanned reconnaissance system that can reach speeds of up to 130 km/h and altitudes of up to 1,500 metres. The six propellers are mounted in groups of three, and rotate in opposite directions. To reduce its infrared and radar signature, the drone is made mainly of aluminum and the engine air is evacuated upwards. Its shape, reminiscent of a peanut, has earned it the nickname “flying peanut.”
