It Is Likely That The Pilot Did Not Have Sufficient Rotor To Avoid Rotor Flap During The Takeoff Roll… Analysis: The pilot taxied to the runway with the rotor still spinning from his previous landing, maintaining above a 100 rotor rpm on his gyroplane. As he taxied onto the runway, he noted his rotor rpm at 117 and he began to accelerate to build rotor speed, pitching back slightly. The pilot heard a loud pop and thinking he may have blown a tire on his right main landing gear, he glanced over to visually confirm it. He then checked his rotor rpm and found it had decreased to 80. At that same time, the gyroplane began to shake and then quickly turned over on its right side and came to rest on the left side of the runway, which resulted in substantial damage to the empennage and main rotor.
