Going OT and probably this discussion could be taken for a new thread for Rotor craft uavs.
IMHO, for transport VTOL, it is preferable to have Chinook style tandem rotorcraft UAVs.
India already has some headaway with Tactical UAV (payload 20 Kgs) called Sabal 50
China already fields heavy UAV (payload 650 kgs) called Boying T1400.

+1 Agree on the more power/payload requirements. We will hopefully have multiples projects to cover the spectrum.
What are the advantages/disadvantages of Tandem Rotors vs Co-axial ones?
