More than a year after staring this damn project, I finally decided what goes where. And on top of that, short description how Dualcopters works (or at least should work).

  1. There are two counter rotating propellers on top. They are responsible for thrust and YAW control
  2. When both props turns faster, dualcopter gains altitude
  3. When clockwise propeller turns faster, whole design starts to rotate counter-clockwise. When counter-clockwise propeller turns faster, it rotates clockwise
  4. Roll and Pitch axis control is archived by two flaps at the bottom of the design moved by two servos
  5. Since propellers are always rotating, there is almost always enoughair passing through flaps to have enough force for stability control and maneuvers
  6. To generate enough torque, center of gravity should be far above flaps. This way, even relatively small force on an end of long lever, there is always enough torque for roll and pitch stability

Dualcopter working principle

Keeping above in mind, it will look like this:

Dualcopter what goes where

What is still missing? Place to put battery in and electronics. Next update as soon as I will have any update ;)
