4 medium poly quadcopter models for a 3d mobile game. -- 2

I am working on a mobile game which includes a quadcopter as the main player. I need 4 quadcopter models for my game each of them should look unique. They should not be very basic but also not too advanced. Medium quality. 4 drone classes - Assault , Short Range Heavy , Sniper , Medic. Medic has a siren kind of light on the top and looks heavy. Has single shooting barrel in front. Assault looks medium [login to view URL] has single shooting barrel in front. Short range heavy looks bulky. Has the bullet shooting barrel on front face(multiple barrels around 3 or 4 in front of drone) Sniper Has shooting area on top. A bit elongated single shooting barrel. All models should have roughly same dimensions(hitbox) and the rotors have to be individually modelled.(just one model of rotor used in all drones)
