I know it looks like the one from Avatar; and it IS based on it, but I didn't have the parts for the propellers on the wings!!
About this creation
Rocket/Missile Launchers. Credit goes to Imagine Rigney for the overall design.

Another shot (you can see the missiles more clearly)
Interior Work station (on other variants this can be replaced with troop benches, a medic bay or a cargo bay)
Side-Mounted Heavy Machine gun

Rear; Note the Rocket exhaust outlets on the wings.
This gunship is based in the Aerospatile SA-2 Samson from the film AVATAR, but it ended turning up slightly different due to the lack of pieces. For example, it is probably significantly larger in minifig scale than it would be in real life, and the rotors have been replaced by wings with rocket engines.
However, this model is too heavy to be picked up quickly in emergency drills, as the tail falls off (as do the side panels!!)!! You will be glad to hear that a new, revised version of this is now avaliable. It has been shortened so that there is a very small bay area, the overall superstructure has been strengthened so it is much stronger and lighter than the other one, the wings have been improved, AND I HAVE FOUND SOME ROTORS!!!
