Today you can hire an instructor to teach you to fly a gyro with all the safety of dual-seat instruction. But now it's different, and the availability of gyro training has generated an explosion of interest in these machines. To learn to fly a homebuilt rotorcraft, you must have training. This is true regardless of your previous flight experience. Fixed-wingers have to learn how to handle an aircraft that doesn't fly like an airplane.
New pilots have to learn a whole new ball game.
Even though the autogyro is the easier to fly of the two types of rotorcraft, it's likely to be too much for a new pilot without training. A helicopter in the hands of an untrained pilot is a certain wipe-out. Some rotorcraft manufacturers offer dual-seat training. Pilots of other models can learn in a rotorcraft that resembles the machine they intend to fly, then transition to their own craft. Most manufacturers of single-seat helicopters reccomend this to prepare you for their ships.
