New rotor way




Hi, i m new to this forum and i want to make RC heli from zero.
I will use all materials from garbage exept the motors.
Above is my sheme of helicopter. I removed the swashplate and other complicate pieces by simpli atach rotor wings to main motor fixing it to heli body but allowing him to move in 4 direction by 2 servomotors.

Please i want to know your opinion on this and can this be done that way?
Tnx

Am I understanding that you want to build a Twin tilting spindle rotor? With an ESC to control speed from both motors and the servos controlling the tilt of the motors?

You will need a small motor w/prop at the back to prevent the copter from turning opposite of the rotor. Or use two vanes beneath the rotor wash to stop the rotation.

Yes i want the rotor without swashplate, i m gona attach rotor wings on main motor and move the entire main motor including the rotor wings in all 4 directions to control heli movment left right forward and backward. That i m trying to achieve by fixing main rotor on body of heli and by hinge (or knuckle or elbow i dont know exact english word for it). That way the rotor wings will get needed angle to move heli. Also i m gona prevent the rotating of main rotor by that dark and light grey wire or something like that. That way main rotor can be moved by servomotors 1 and 2 in all for direction while hinge is providing angle of rotor wings.
Can it work that way?

I assume you mean the radio or Tx to controll the motors and servos.
I would look around for a heli radio something like this--

If you want to build it yourself, you could search through here--
