Why don't airships / blimps use frontal stabilizers or thrusters? Is there any reason why frontal stabilizers aren't used on blimps or airships to ease maneuverability in, e.g., gusty winds? Even the indoor blimps have a tail rotor, not the nose rotor for rapid yaw movements.
Also, is there any reason why the "pusher" motors are used instead of puller-ones in the front (with an exception for the Lockheed Martin P-791)?
It depends if you want stability or manuverability. see this video. 


                
            

It also has to do with if you want to attempt to keep laminar flow over the nose of the airship...
