EXI 500 carbon before integration in my 500E Align fuselage. This is the7th flight and despite the opinion of the manufacturer of the pentablades, this 5 blades rotor head is not ready to use. Dismantle and add locktite to the blade holders. I lost a blade durind this flight. Scary even at this low rpm. No 3 axis gyro, Rc Aerodyne plastic weighted blades.
