LEGOŽ set 6745 sure is a fun set from which to build alternate models. The official instructions for this set include 2 airplanes (a jet fighter, and a cropduster), and a helicopter. Up to this point, I had not made a helicopter alternate. Therefore, I thought it would be a good idea to make an attempt.
My grandfather worked his whole life for the American aircraft company, Lockheed. Back in the late 1960's Lockheed was involved in the US Army's Advanced Aerial Fire Support System (AAFSS) design competition to develop the Army's first dedicated attack helicopter. Lockheed's entry into the competition was the AH-56 Cheyenne. This alternate model's configuration is based on that of the Cheyenne.
One of the more unusual characteristics of the Cheyenne was that it had three propellers. The main rotor on the top, the normal side-facing rotor to counteract the torque of the main rotor, and an unusual pusher propeller. The pusher propeller in the back gave the Cheyenne a very fast, top end speed.
Another strong design point of the Cheyenne were the short wings on either side of the helicopter. These wings generated extra lift at high speeds, and enabled the helicopter to carry a significant array of weapons. Including the then fairly new TOW missile system.
Retractable landing gear was also very helpful in eliminating as much drag as possible and thus increasing the top end speed. My model includes this retractible main landing gear.
The original helicopter carried a crew of two, a pilot, and a gunner. The gunner sat in the very front and had a great view from the extremely large canopy.
In the end, only ten Cheyennes were built as the program was cancelled before production began on the initial order of more than three hundred. For this model, the end will come when I get the itch to try to build something else from this versatile set.
Quoting Agent X Do you have a mac? Just wanted to know because you said Bricksmith.
Yep, I use a Mac for most things, including virtual LEGO models.
I like it

Love the use of the reflection off of your car! I really like the landing gear and the nose of it. Do you have a mac? Just wanted to know because you said Bricksmith. Anyway can you tell them to invite me to Micro and Mini Mocs. See ya!

Did you take them with your model on a car?
I'd like to give a try as well to build a helicopter instead of planes.
What will you build next...
Hi Nathanael: Thanks for the kind words. Yep, I took these photos with the model sitting on top of my Honda Fit (I think it is called a Honda Jazz elsewhere). I liked the reflection underneath the model and the reflection of the sky as well.
I am looking forward to seeing your helicopter!
What's next? I have a couple ideas...my wife suggested something slower. I might have to wait a bit though because I'd like to develop my skills with "Bricksmith" (the 3d LEGO CAD software I use) before taking this helicopter apart. We'll see.
Another great alternate, Dave! I especially like the top view. Also your photo's are great again. Did you take them with your model on a car?
I think we've both proven that this set is excellent to MOC with. I'd like to give a try as well to build a helicopter instead of planes.
What will you build next...
