yup thats one of the other prototypes, totaly based in the francgerman tiger, with a modifies tail wing, the other is as above with armoure tail rudder and internal rotor.
reason i pointed to the internal rotor was that they are already making the rotors for it, and full testing is being done on their civil fleet first, as they do the hours so a good test.
thats said the 4 blade prop is cheaper and is the direction the tiger took adn all the WZ-10 is, is a modified tiger, the copter its based on is evan the chinies copy of the europcopter that uses the enclosed rotor.
this is the eurocopter the tiger uses bits rom

you can see why the wz 10 was considering using the same tail design, but may take the tiger rout.
enclosed rotors are great for saftey reasons, but do increase profile size of tail and weight.
id like to see the MGP WZ-10 have an enclosed rotor just so its instantly recognisable from its near identiacle cousin the tiger.
