No Zulu Cobra in 1/35, actually none at all yet in any scale other than a couple of toy like ones.
OK...just an FYI.
Academy AH-1W will run you $40.00, AFV Club also has one, which I think from their past collaborations is actually the same kit as the Academy one....I could be wrong about that, but I believe it is infact the same kit. And if so...the Academy one is cheaper as the AFV one goes for $60.00
Aftermarket, while the Verlinden set is available for $29.75, the Cobra set actually gives you all the NTS upgrades as well. Not sure what else comes with the Verlinden set besides the cockpit, but the Cobra set is the cockpit and the NTS upgrades. Cobra set has to be sourced directly from them however.
PE....Eduard has 3 sets.
EDU-32087 1/35 Aircraft- AH1W Super Cobra Exterior for ACY - $27.50

EDU-32091 1/35 Aircraft- AH1W/T Super Cobra Armament for ACY - $25.50
If you don't want to scratch the tractor, the verlinden one #2634
Looking at $38.50, but it is 1/32, and not 1/35....but likely close enough.
I thought Skunk Modelworks made one in styrene, but it is 1/48
