Ready to fly!
Ralf Spoerer is excited about the RTF concept (ready to fly). ‘It means I can now control four small drones and two large Hexa-copters straight from the box.’ High-power lithium-polymer batteries allow for flight times of around 15 minutes and with the help of an integrated GPS system they can be controlled right down to the exact position. The drones are fitted with a so-called Gimbal, which balances the movements on the drone thanks to control commands and thermal currents: the camera is steady at all times, so it cannot shake or produce unfocussed pictures.
Photographs shot by the camera are then sent by radio directly to the pilot’s screen. ‘This allows me to measure the exact perspective, distance and cut’, explains Spoerer. Aerial photography is demanding and requires the appropriate equipment and know-how. For this reason, not only is Ralf Spoerer a professional aerial photographer but he also passes on his knowledge to others in his ‘Drone College’ workshops.
