RAH-66 Comanche

Post by DRUMS01 »

Image

Overview

The Boeing–Sikorsky RAH-66 Comanche is an American stealth armed reconnaissance and attack helicopter designed for the United States Army. During the early 1980s, the U.S. Army started to formulate requirements for the replacement of its helicopters then in service, which resulted in the launch of the Light Helicopter Experimental (LHX) program. Nearly a decade later, following the refinement of requirements, evaluation of submissions, and the rebranding of the programme as the Light Helicopter (LX) program, during April 1991, the Army announced the selection of the Boeing–Sikorsky team's design as the contest winner, shortly after which a contract for construction of prototypes was awarded. The Comanche was to incorporate several advanced elements, such as stealth technologies, and a number of previously untried design features. Operationally, it was to employ advanced sensors in its reconnaissance role, where it was intended to designate targets for the AH-64 Apache. It was also armed with one rotary cannon and could carry missiles and rockets in internal bays and optionally on stub wings for light attack duties.

Model Kit

As shown on the box art, this is a 1/48 scale Italeri kit made in Italy. The kit is very simple and contains only two sprue trees molded in dark green plastic. There is also a clear sprue (with scratches), some screen for the intakes, and decals.

Image

When looking at the mold quality it seems to be something between the first prototypes and what the design team envisioned as the final variant. While the cockpit glass is cleanly molded, most of the panel lines are too deep and do not match up with the source photos. The cockpit is very simplified with no detail on the inside of the fuselage. The seats, control panels, and rear bulkhead beg for more detail. I should also note that the kit comes without any crew figures. So if you want to build the Comanche in flight to better show off its stealth design, you will need to source the pilot and gunner. There is zero detail in the landing gear bays while the internal weapon storage areas have some basic rib and wiring detail.

The model can be assembled in three different armament configurations:

Image

I am going to build my kit in the "attack" mode, but I am not completely sure if mine will be in flight or on the ground. Funny thing is the model is of a fully armed production model but the decals provided are for the two prototypes, go figure... I've always wanted to build this kit since I saw it in a Janes weapons update many years ago. While these 1/48 kits are apparently hard to get, I have seen a couple on-line built into some impressive models. I'm also not quite sure how much extra detail I will add, but follow along and feel free to provide ideas and input towards my build.

Next update will begin the build process...

Re: RAH-66 Comanche

Post by DRUMS01 »

So the progress on the Comanche is dragging. I decided to build my RAH-66 in flight to showcase the smooth / stealth bodywork. That decision impacts the build in several ways:

1) In my first message I indicated that this kit does not have any pilots, so I ordered two resin crew members in 1/48 scale.

2) Looking at the seats in the kit all I can say is that they are severely lacking. So I am looking at replacements or just how to upgrade the kit "chairs". I know the real ones are not ejection seats, but the detail on some resin replacements, if properly modified, could really add some detail (?).

3) I also mentioned in my first my message that the decals are only for the two prototypes while the kit is for a fully armed production model. To fix that I looked at what was available for other 1/48 Cobra or Apache variations. I purchased a Caracal Decals 1/48 BOEING AH-64D/E APACHE Attack Helicopter sheet that has numerous options for 16 different war birds.

4) I previously mentioned I was building the Comanche in the "Attack" configuration. Specifically, I am loading Stinger and Hellfire missiles inboard and two types of Hellfire missiles on the wing stubs. The problem is the kits Hellfire misses are very generic looking. Eduard makes an after-market set with P.E. fins and separate clear eyes or gray tips that have a much better appearance than what the kit has to offer.

5) The cockpit panel details do not match those of the actual aircraft. I do have to give Italeri some credit though as what is there looks good, it just isn't enough... again too generic. So I've purchased some P.E., placards, and Quinta 3D decals to refresh the cockpit.

So I'm currently waiting for all these items to arrive.

The paint scheme on the box and within the instructions call for the Comanche to be solid F.S.34087 Olive Drab. I am thinking of making it some other color or a combination of colors. I think that a digital desert camouflage or even a European Forest camoflage would be really neat. Perhaps a three tone black, dark gray, light gray camouflage could work too? What colors do you all think would look neat on this?

Let me here you on this please....

Re: RAH-66 Comanche

slowly moving forward....

Thanks to all for your input regarding the color(s) of my Comanche. Based on what everyone has said you brought me to another option all together... I am going to use the traditional Green, along with desert tan, and one more color (either a rust/brown, or gunship gray). The way it will be applied will be through a digital camouflage in a disrupter kind of scheme as shown below. I may or may not decide to paint the belly in a light sky blue (still thinking).

Image

After looking at the cockpit, I've decided to use the kits seats with some modification and other details. The dash panel of the cockpits front and rear areas does not match with that seen on the actual aircraft. I've decided to scratch build them with a combination of sheet styrene and 3D decals (waiting for the arrival of the 3D decals). The side panels will also benefit from the 3D decals after I modify the panel layout to something more in line with photos. I received the figures for the cockpit and think they will fit fine (see below).

FRONT SEAT (Prototype 2)

Because of the lack to any detail in the landing gear tubs and because I want to show the clean lines I am building her in flight. I have purchase three stands of various size. Once they arrive I will know which one to use.

Being a "stealth" copter, I am going to focus on three major areas: 1) the cockpit, 2) the paint/decals, 3) the weapons bay and components. Unfortunately, most of it is still in transit.

Next update should finally have some the purchased items along with photos showing some of the work performed, till then....

OK, Lets get started... STEP 1 The Cockpit

Image

As you can see with the images, it does not have the same shapes or detail of the original aircraft

Image

Image

The first area to modify was the arm panels in the cockpit to better match those of the actual helicopter. My goal is to extend the small rectangular shapes so they connect to the side walls of the cockpit (as on the actual helicopter). These flat sheet plastic parts will need to have two tapers. One from the back to the front of the cockpit and the second from the lower to the upper portion. In order to get a more accurate position and contact I removed the little bumps on the rectangular shapes molded into the cockpit (see photo)

Image

Next was the careful shaping of the panels to smoothly tie into the cockpit walls and then attaching them to the cockpit base. In the picture below you can see the 4 shaped horizontal panels attached. The rear instrument panel face has been rough cut to replicate the photo while the kit panel has been trimmed down flat to accept the new facing. Some of the detail work has been started on the seats.

The drawing below gives better detail to the seats. The kit seats laid flat on the floor of the cockpit while the photo shows they are elevated and have tubular support bracing. In the second photo the solder represents the seats initial tubular sport bracing and the flat pieces behind the headrest and seat back fill in the hollow part in the model kit and represent the backs of those parts. The seats have been slightly elevated using small squares of sheet plastic to better replicate the Boeing drawing. The remaining (upper) tubular bracing will be added when the seats go into the cockpit.

Image

Image

Here is a bonus photo showing the upper and lower torsos of the pilots attached and sitting in the seats.

Image

Tomorrow I hope to have the seats and the main parts of the rear cockpit finished, less the 3D decals.

Step one also includes the assembly of the front sensor array. This is something that would be on the actual production version but was nothing but a dummy shape grafted into the fuselage for the prototypes.

Image

Image

Another part of Step 1 was the assembly of the 20mm three barrel gun turret which mounts below the sensor under the front of the aircraft. So far the only details I've completed on this was drilling the holes in the triangular braces (as on the real aircraft). I still plan to add hollow brass tips to the three barrels or drill them out before completion.

Image

Image

My next update will talk about the remains item in step 1, the enclosed tail rotor.

Till then please provide your input or comments, THANKS!

Ben

Re: RAH-66 Comanche

I don't have much to show as I am still waiting for some of the "stuff" to arrive. One thing I did finally accomplish was the final shape of the rear instrument panel. In the previous photos you can see the difference. After around 9 pieces for the panel, this is what I'm going to use with the detail items (less some minor adjustments). I still need some fine tuning on the right rear arm panel and the seats are unfinished as well:

Image

Image

Since the cockpit is on hold I started on other parts of the Comanche. After looking closely at the weapons bays I noticed only some partial detail on the inside wall. Checking out the drawings and other photos I decided to add more detail in there. First I started with the panel reinforcement spars by continuing them from the inside wall to the top of the weapons bay and on the bottom of the inside wall:

Image

These photos show the scissor hinges and hydraulic actuators used to open the weapons doors and extend the payload:

Image

Image

Image

So my thought was to create some of this detail and here is what I have so far. It represents the actuator along with some pivot pin ends where the scissor linkage folds. My hope is the illusion of multiple pieces and that the actuator closes while pivoting up into the fuselage while the brackets fold into each other at the pivot points thus allowing the storage space for the weapons:

Image

Image

I still need to create the internal reinforcement ribs to the weapons bay door structures (as seen below), add the door hinges and cylinders to the doors reinforcement ribs, as well as create and add the Integrated Armament Interface Unit I-AIU. I am also thinking of adding thin metal foil on the front and back of the bay area to appear as in this photo:

Image

Actually, there is not much more in there as the payload takes up all the remaining space when stored. I've also added things to the model already like the doors for the front landing gear (since it will be in flight), screens for the engine intake, drilled out the 20mm gun barrels in the front turret, etc.

While waiting for the purchased items, I may move on to the rotor assembly, build the weapons load, rework the front instrument panel, or modify the figures for the helicopter controls (?). Always stuff to do.

If anyone is following along, feel free to leave a note and ideas..... :think:

Re: RAH-66 Comanche

Been some time since posting anything so.....

- reworked the scratch built parts of the cockpit and added armor around the seat areas (previously overlooked). In the photo you can see the engine inlets also painted. They have since been added to the inner fuselage. Not much can be seen of them unless you look at the perfect angle with a light, oh well... at least I know it's there.

Image

In the photo above you can also see the updated seats. Here I added the EES initiator bracket to the front of the seat. Also finished the rear tube braces, the vertical position adjustment handle, the arm rest tilt control, and the side arm position adjustment pin. Here is how they look prior to any detail painting:

Image

Next was to fiddle with various after-market products to come up with a close replica of the actual cockpit consoles. After many modifications here is the end results:

COCKPIT ARM PANELS: (crew members are still a work in progress)
Image

FRONT SEAT (PILOT) DASH PANEL:
Image
ACTUAL:
Image

REAR SEAT OPERATOR (RSO) PANEL:
Image
ACTUAL:
Image

EVERYTHING:
Image
Image

I still need to pick out some detail items with a hairy stick (buttons, warning lights, etc.) and weather the whole cockpit, but this is what I'm going to work with. I also built the main rotor as far as I could before painting:

Image

And to continue from the previous update, here are the weapons bay doors with the reinforcement ribs added. The door actuator will attach to these ribs as on the real aircraft:

Image

Image

Till next time...

Re: RAH-66 Comanche

Post by DRUMS01 »

Thanks digger, I spent more time on it today and here is what was accomplished:

- added screen images in the cockpit displays since it is in flight.
- finalized the detail on the pilots (repositioned arms/hand, shadows, unit patch, etc.)
- weathered and highlighted the cockpit.
- assembled the cockpit components (dash, seats, crew, control sticks, etc.)
- assembled cockpit into fuselage.
- added sensor and gun turrets (not glued).
- attached both halves of the fuselage.
- de-seamed the fuselage.
- added the gun turret fairing.
- chose display stand, modified and assembled it.
- fitted brass collar to display stand.
- flared brass collar and attached into drilled out hole under fuselage.

There are a couple items I still need to finish:

- touch-up cockpit edges
- add seat harness straps from pilots to seats.

IN FLIGHT:
Image

FROM THE TOP:
Image

COCKPIT DISPLAY DETAILS:
Image

FROM THE FRONT (notice drilled 20mm barrels)
Image

Next step will be enclosing the rear landing gear, the exhaust defusers, adding the horizontal stabilizer to the rear, etc.

I hope to have it fully prepared and ready for painting at next update. Till then please let me know your thoughts.

Thanks digger and BigWall...

If I would've made the rear panel .01mm wider the canopy would not have fit properly. As it is, it is a very tight tolerance.

Looking at the digital camouflage pattern I want to apply, it will be difficult for the armament wings, weapons bay doors, front turrets, and rotor blade cover to perfectly match the fuselage pattern, but I will give it my best shot.

When combining the fuselage halves I noticed that the sensor window above the gun turret is off center. I wonder if that is by design or poor molding. Either way it is too late to change that now.

Also still pondering the weapons configuration, perhaps more to show on that during next update.

Hi everyone.....

I have been on a slow crawl working on this as spring time and outside chores have pulled me away. Still, I've been able to get more done. In fact I am very close to fixing a couple seams, attaching the canopy and preparing it for paint. Some of the stuff I've managed to do are below:

Added screens to the oil cooler exhaust (top by the rotor), and the port/starboard sub-systems power unit vents. Notice the high and low panel points on the fuselage, this is a problem throughout the fuselage. While it does not have many recessed panel lines, many of the ones that are there do not line up from one side of the fuselage to the other. Those have been rescribed. I'm leaving the depression by the rotor head as it will be covered up when the rotor is in place, but it gives you an idea of the bad panel fitment.

Image

Added the tail wheel landing gear cover and the weapons bay doors. Painted a base coat in the weapons bay. In this photo you can also see the brass tube added for the display stand as well as the main seam beneath the fuselage still requiring some filler. There will be much more detail painting in the weapons bay after the camouflage is finished. I plan on painting the wing stubs separately.

Image

Started on the replacement weapons I ordered from Eduard for the Hellfire missiles.

Image

After looking at the weapons mounts I decided to keep the kit parts and detail them with PE and scratch details. Here they are partially completed.

Image

Next was the building of the hellfire missiles which comprised a resin center with 8 separate PE fins, a tail cone cover, a PE mounting bracket the size of a pin head, and a clear or gray nose. After a couple days of assembly, I' ve managed to attach everything (11 pieces per missile, 88 pieces total). The front fins were a challenge as they were not much larger than the tip of my tweezers. I only lost one of the 32 front fins which I replaced with a similar cut piece made of sheet brass; for me that is success. Here is a photo prior to completion and you see the size of the small front fins. Afterwards I had to rework each fin (front and rear) to remove the PE attachment points as they were too small to hold and remove prior to assembly. The finished details on the Eduard missile can be clearly seen when compared to the kit missile below.

Next will be finishing the fuselage seams then masking for primer/paint :th:

Re: RAH-66 Comanche

Sorry for the delays in updating this build, but here we go...

Since last post I've added the fixed rear tail plane; added the exhaust defuser covers, added the blade antenna beneath the fuselage; scratch built the first aid kit within the cockpit (see below); corrected the rear landing gear doors (putty and re-scribed); cleaned and filled numerous seams, etc. Something of note, the fixed rear tail plane does not have any pins or reference points so its is easy to attach it at the wrong angle and pitch if you are not careful.

Image

Image

One item that took considerable time was removing the heavy scratches from the canopy. The clear plastic is very soft. Because of its softness it was difficult to remove all the the scratches without adding stress marks in the plastic. At a certain point I had to call it "done". Next came the assembly of the two canopy doors to the main part of the canopy. I quickly found out that the model is designed to pose the canopy doors open. Specifically, the fit of the doors in the closed configuration did not fit the canopy or fuselage properly. After some careful filing I was able to add them to the main canopy, clear coat the inside to reduce the scratches and stress lines further, and then add the canopy assembly to the fuselage.

While working on these items I also noticed that the model kit does not have any indication of the items listed below. I will add them with decal and paint during final assembly.

- IWR antenna near the top of the engine enclosure
- VHF antenna on the leading edge of the canted tail fin
- UHF antenna centered in the right half of the fixed tail plane
- GPS antenna left of center in the fixed tail plane
- upper IFF antenna centered in the left half of the fixed tail plane

Image

Prior to painting the base coat I began work on other sub assemblies:

- I located a lapel pin on-line for the Comanche that looked like a good fit for the display base. Once received I removed the pin, filed it flat, and glued it to the base; here is the result:

Image

- I chose to add the "Stinger" missiles to the weapons configuration, so I had to paint and detail them. The colors come from internet research and the control box was created from plastic stock and added. Once they were painted I added them to the pylons. All that remains are the decals and some weathering.

Image

I finished the external weapons racks to include numerous pieces of P.E. and some solder for the electronics wiring. Afterwards they were painted medium green FS 34102. I still plan on applying a dark wash and picking highlights or dry brushing and decals.

Image

Image

Regarding the weapons configuration, I noticed on some images that multiple variations of TOW Missiles can be configured as seen below. I am planning on doing the same to this Comanche.

Image

Next came the masking of the canopy and applying some paint. The base color I selected was desert sand. Here is a picture of the first color along with the wing stubs and rotors laying in place (not attached):

Image

As you can tell, I'm not going to color it in the multi gray tones as I thought the actual gunship would've been initially deployed to the Middle East or Europe. The mask set I started with came from a 1/48 Russian aircraft and was modified (cut) to fit the Comanche. The challenge of this camouflage scheme is to apply the angles in the same direction and in this case orienting them from front to back.

Image

Prior to adding the second color I applied the second layer of modified masks. The second paint color I'm using is light earth. Once the masks were in place I applied the paint:

Image

Image

Image

This is where I'm at, waiting for the second application of paint to dry. Once I'm confident the paint can accept the masks I will apply them and spray the final color. Till then please let me know what you think of her so far (thanks)....

Hope everyone is healthy and enjoying this early summer....

Well, I was going for something different and not the standard U.S. Army Helo. green. Initially I was going to go try-tone gray for urban / city combat, but changed from that too. Then I was thinking about a desert scheme and figured that was too tame. So after three layers of mask, paint, and removing the stacked masks....

Image

This is where I got the color combination (even if it was applied differently):

Image

Here is my very different color treatment, I have never seen this color combination or scheme on anything flying so I think I achieved my kind of "different": (desert tan, light earth, and medium green)

Image

Image

Image

Image

Image

Still have to touch-up or fix some of the color applications, gloss coat, decal, clear coat, wash, flat, etc., etc. I will need to repaint the weapons bays and finish the remainder of the assembly too.

Till next update.....

Ben

Fantastic build. I'm gutted I didnt see this thread earlier.
Its been tried and tested, it works! So don't blame the system if you're no good. :doh:

Why thank you digger303 and Stokesy44. This kit is way out of my comfort zone. Its lack od details in the weapons and landing gear bays along with the basic detail in the cockpit make it something difficult to get excited about. The mold quality with regards to gaps and panel fitment leave something to be desired too.

This is my very first build with 3D decals and quite frankly, I love them. There is no way mortal modelers could achieve the level of crisp 3d detail in scale without them. This is also the first time I tried a multi layer masking and spray to make up a digital camouflage. I need to add that this is my first add on weapons with PE details. And I should say that this is my first "what if" aircraft build ever. Normally they are something specific and legit.

When looking for the stand, I was trying to come up with a data plate to identify what it is. The trophy shop in town closed so my source for metal etched plates was gone. I began looking for coins or stickers and found this lapel pin. Lucky for me its size fit the base and after some modification it finished the base off (IMHO).

Thanks once again for the comments and following along.

Finally, after many trials and nearly being placed on the shelf of doom, I pushed through this one and I'm calling it
D-O-N-E! While the photos may appear as semi-gloss, the actual aircraft colors are really flat.

Not my best work, but it is finally off the bench.

Comments welcome (I can take it).

Awesome result despite your own criticisms. One would need a optivisor to see any faults.

Re: RAH-66 Comanche

Post by DRUMS01 »

Thanks everyone. When I was working on it I found the panel gaps to be terrible. Some of the detail was half way between the prototype and a front line production model. The cockpit was totally wrong and generic when compared to the actual aircraft photos. Likewise the wheel bays were totally devoid of any detail and the weapons bays were very basic. The canopy had a couple large and deep scratches when opening the box but I was able to polish most of it out with very little stress cracking (very soft clear plastic).

I can totally recommend the Quinta 3D decals. They are multiple layers (thick) and designed to lay on a smooth panel. This means any existing detail from the mold will have to be removed prior to applying the 3D decals. They are pliable, easy to set, super detailed and layered correctly to replicate buttons, switches, etc. As for my future builds, anything 1/48 or larger with plenty of cockpit glass will definitely have Quinta 3D decals applied if available.

When painting the camouflage I accidentally applied the last two layers of paint a little thicker than I should've (my fault #1). The masking material indicated in its instructions to not leave it on any longer than necessary. So what did I do?; I left the mask on for over three weeks (ensuring each color coating was totally dry) (my fault #2). It was very difficult to remove but not as bad as the tape over the canopy with four layers of color, two clear, and one flat (7 layers). The trick with the taped canopy was to carefully scribe the paint edge of the tape prior to removing it (my fault #3).

The Caracal decals work almost perfectly except the left side US Army decal which frosted just a little regardless of what gloss or setting solution was applied. I would still recommend them as all the others were durable yet easy to work with. They were not thick but totally covered with no bleed through, and settled in the curves or panel lines well. I used solve-a-set to snuggle them into sharp areas.

This kit fought me all the way (some of the frustration was my own fault), but I guess it came out OK. Thanks everyone once again for the kind words. When all said and done, it does match my intended vision of the completed model.
