Bell Helicopter models

I believe your best starting point will be the 1/35 OH-58D Kiowa Warrior produced by MRC. It is the US Army's up-gunned attack/observation variant. Being the militarized version, the kit will need some serious modification to give it a civillian interior and to rework the doghouse fairing -- but this is still the way to go for your 407.

Thanks for the heads-up.  I will have to decide if the modifications are worth the effort right now.  I had actually thought about taking an Apache or Blackhawk and painting it with the TV station logos, along with the ordnance.

Making a 407 from an OH-58D is nearly impossible.  The 407 is bigger, heavier, and more powerful.  The new ARH-70A Arapaho is a military version of the 407, but there is no kit available yet.  You may have to wait a couple years for that.  The Arapaho is proceeding slowly, but operational capability is still a few years off.  And of course, there's no kit of the civilian version out there at present.  Closest you can get is a Bell 206B3, which is what the Heller OH-58A kit really represents. 

HTH,
