Hi Vortmax,
In 1:48 there is the Italeri (ex Esci) Bell Kiowa, the military variant of the Bell206 JetRanger. Main differences are smaller windows and an open, visible tail rotor drive shaft on the military machine. Whirly Bits has a conversion set to turn the Kiowa into a civil machine: doors with big windows and a tail rotor drive shaft cover.
Sometimes one can still find the old Esci 1:48 civil JetRanger kits, f.i. the LAPD version. In my opinion the old 1:48 Esci kits are the best Jet Ranger models around.
Hth,
Best Regards, Gertjan
Btw: what type does your TV station fly? The 407 and 206 are quite different and there are no 407 kits available (maybe that will change now that the 407 has been selected by the US army as scout helo).
