Klingon D7 from Arkansas [ Cyberplanes kit ] - Star Trek

Sometimes, you feel the Call of the Warrior......

I will be constructing a "Klingon D7" from Cyberplanes:
http://www.cyberplanes.com/index.php?productID=158

This is an electric, EPP foam model. It is a kit, but certainly not an ARF. Took about 10 days to get to me.

Wingspan: 34 inches
Length: 39 inches

And here is what you get:

Background

The Klingons are a fictional race from the Star Trek universe. They have appeared in several movies, and in all the series.

The D7 is their main starship in the original Star Trek series. It is also referred to as a "K't'inga" class cruiser in the opening scene of Star Trek: The Motion Picture.

Even though there are a few differences, the Cyberplanes model seems to fairly well represent the D7 look, with some allowances made for aerodynamics.

The aircraft is designed to be built using hot glue (my first experience with the stuff).

Rather than written instructions, it comes with an instruction video, which is well done.

Main Hull

Starting out with the Main Hull: two big hunks of EPP foam that you glue together.

I glued the longer section first, using the hot glue. After applying glue, held them together on a flat surface: my workbench.

NOTE: There is a TOP and a BOTTOM to the Hull. It is defined by the bevel at the back of the two pieces, where the ailerons attack. The flat surface is the top of the hull. The beveled surface is the bottom.

Hot Glue

Here is the hot glue I am using. Got it at Wal-mart.

Once you get the Hull haves together, you attach the carbon rods, which are included with the kit.

I originally thought I could just use an Xacto hobby knife, but that did not work.

Again, I had to make a "bevel", which is an angled section cut out of the foam. What seemed to work best was a razor saw (red handle).

Forgot to show: I marked the location of the rods with a silver Sharpe.

To place the rods, I ran a line of hot glue in the bevel. Then I IMMEDIATELY placed the rod in position, and pressed it in a little. (Yeah, you get glue on your hands. But it comes off easy.)

I installed the rods one at a time; you MUST act quickly before the glue dries.

Once all rods were installed and dry, I went back and added glue over the top of the rods/foam.

Hull Support

I am been impressed with the thought that went into the design of the D7 by Cyberplanes.

The model has a 'hull support' for you to land on, so you aren't tearing up the boom/bridge and the warp nacelles. (If you don't know what that means, just keep following the build.)

There is a 'ridge' that turns out to be a landing skid. I made Sharpe marks at front and back so I could align it.

Per the video instructions, I added gussets of hot glue.

Assembling/attaching the boom is next.

The battery (11.1v, 2200 mAh) attaches to the boom, just under the hull. But the place on the boom had to be widened for my 2200 mAh battery.

NOTE: The boom section has a reinforcing wood piece. Very good idea.

The boom is attached to the hull. Measured, marked w/ a silver Sharpe.

Also used T-pins to hold boom in location while marking contact area.

More boom work.

Added 1/8th plywood to help hold battery. Used hot glue to secure it.

Here is the assembly so far. There is a yard stick [36 inches] for scale. (A little less than a meter.)

By the way, here is half a sphere, that is the "chin" of the boom.

It was originally white, but I painted it black so it will show a similar color when the overall paint job comes.

There is also a small amount of fiberglass cloth epoxied to the chin to help protect it.
