I just wanted to share my latest video of my homebuilt autogyro. It is almost five years old now, and I do not fly it very often. Since all old videos of it are old and bad quality, i desided to make a new one. The autogyro itself is my own design and the result of some testing. What makes this design uniqe is that it is equiped with an electric prerotator to spin up tor main rotor before takof.
Plans and more detailed info are avalible on my website: http://axelsdiy.brinkeby.se/?page_id=354
The rotor is started with a brushed Speed 280 motor using a friction drive system.
The Speed 280 motor is controlled using a solid state power switch (seen in image above) conected to a PIC microprocessor (seen in image below). It listens to the signals gonging to the servos and is it senses that the rotor is tilted fully backward and is centerd, the pre-rotraor motor is started.
Large standerd servos are used to tilt the rotor farvard and backward and left and right. The autogyro also has a rudder but no elevator
The rotorhead is also my design, based on some resurch on RCgroups.
