[TLCB Lockdown][C-model] VOMAK AT4-V8 Attack Helicopter

Recommended Posts

Posted (edited)

This model was the result of a choice I had to make. I could either come up with an entry for the Eurobricks small car contest, or I could enter the TLCB Lockdown Competition. I really didn't feel inspired to make a small car, so I went with making a C model. I chose 42098, largely because of the fact that it was the only set I hadn't started to mix into my large collection. Initially, I was going to build some kind of wheeled vehicle, but then I hit a real builder's block. At that point, I was looking at the small wheel arches, and thought that it looked kind of like the bottom parts of an attack helicopter cockpit. After I realized that, I made the cockpit section, and got going from there.

This helicopter is ultimately a nonesuch, and combines design elements from a number of real and fictional helicopters, including the Hellhound helicopter from Patlabor 2, and a design I found on Deviantart called the Fujin, which was designed by MeganeRid,

The rotors spin, obviously, but they also have collective pitch control, which was very hard to implement given the parts available in the set. 42098 includes a shockingly small selection of gears and other technical bits, so I had to get very creative.

The rotors are at their lowest position in this picture. The collective does not use a turntable, but instead uses a brick built solution that hearkens back to the very first Technic helicopter, set 852. The actual control for this function is a lever with a red bushing, on the right of the photo.

This is the blades at maximum pitch, which better shows the collar that is used to simulate a swash plate.

The second most major function is the complex landing gear. A 12z gear at the end of both wings controls this function, which uses worm gears to prevent the gear from collapsing.

The first pic shows the gear retracted for flight, the second and third show the gear down for landing.

The last set of functions relate to the gun pod, mounted under the fuselage.

The pod can be traversed 90 degrees to either side, and will clear the landing gear towers. This is controlled by  a 12z gear located behind the air intakes. The gun will also elevate from horizontal to almost vertical, using a knob on the back of the pod.

The gun pod, up close. The rubber connectors on the forward fuselage are actually a travel lock, and can hold the gun in place when not in use.

Maximum elevation. Or is this depression? I can't decide how you'd define this.

On the tarmac. The landing gear do work, but I also built a stand so that this heli can be posed as if in flight, with the gear retracted.

Some up close pictures:

This detail is actually important. As most of you have probably noticed, this helicopter has no tail rotor, and is not coaxial, so what gives? My vision is that a real version of this helicopter would use a NOTAR system, which uses a ducted fan to effectively replace a tail rotor. That's what the large vents on the tail are supposed to be for.

Now, in terms of scale, this model is quite large. CamelHog the hedgehog and Spam for scale.

One last beauty shot:

The color scheme may not be very military, but I'd chalk that up to this being an airshow/display team livery.

All in all, I am quite happy with this model, it was a real challenge to make in the limits of the parts I had, so much so was actually running out of 3L pins, but it came together nicely, and the color scheme actually worked out a lot better than I expected it to.

Now, on to the contest. Stay safe out there, folks.

P.S. I'll give a shout out to the first person who is able to guess where the manufacturer's name of this heli came from.
