Remotely piloted helicopter and rotor head of remote control helicopter

摘要

To improve the operability and to stabilize its flight operations when forming the compact and light in indoor for the R / C helicopter rotor of a single type. Is divided into a lower and upper center hub center hub center hub that supports the rotor head to the main mast, to freely set appropriately fixed angle around the axis of the main mast, respectively. I mounted for operation input from the swash plate, the phase angle of the main rotor to be output is an acute angle, so as to rotate the stabilizer and main rotor while maintaining the phase difference between the acute angle.
