    The pitch of the blades are fixed relative to each other. So they can still twist in the "feathering" axis (with one blade pitching up and the other down by the same about), giving you roll and pitch control (cyclic). 

    There is no collective control, where the pitch of each blade can be increase to produce more lift.  More lift is generated by increasing the RPM of the rotors.

    how are you controlling the drone in pitch and roll if it have fixed pitch rotor-blades?

    Very similar to a Canadair UAV design used by the Canadian military.
