Check out Cobra Company site for new 1/35 CH-47A detail sets (12/03/06)

O.K. Guys, I received these sets two days ago and started cleaning them up. The components for the Aft Pylon/Ramp interior are OUTSTANDING! The two most needed components(APU and Aft Transmission) are nicely replicated and will go a LONG way towards filling the void in this area.

As the Chief Snake points out in the instructions, there is no practical way to replicate the plumbing on the the right and left hand sides of the ramp area let alone all the pressure and return lines from the utility and flight boost pumps and the wiring from the generators, so GOOD reference material is a must. The Aerofax book (if you can find it) gives some basic idea of the ramp areas, but it kind of thin as to the plumbing on and around the aft transmission. I haven't seen the Squadron book so I can't speak to that.

For myself, I am having to rely on the "yearbooks" from when I was with the 213th Avn Co 1981-84, 1987-90 and 1994-95.

These sets are worth every penny and will help fill up the void in the *** end of this model. Couple these with the Eduard sets and you'll be set. Too bad the manufacturer couldn't have given us a little more in the way of interior detail

Not me, Backdating a D to a C is going to be work enough, going the other way would be way more than I could handle, plus I don't know enough about the E besides the landing gear, fuel pods, refuel probe, minnigun installation and wx radar to even know where to start (Glass Cockpit, secondary armament, external hoist, FRIES gear etc...)

Besides, I kind of have (mixed) emotional ties to C models.

Thanks Chris, that is great! I will be good for at least two of whatever you come up with!

I would like to model the "C" version. would updating the Trumpeter "A" version be easier, or backdating the "D" version?

Without a doubt, converting the D to a C would be easier for the following reasons,

1. The Aft Pylon has the correct shape at the trailing edge for the C model, on the D model kit you would have to fill in the cut out for the combining transmission on the leading edge of the aft pylon, and the cooling vent above the APU exhaust on the trailing edge of the aft pylon. The vent on top of the forward pylon will have to filled in.

2. The Aft Landing gear struts and tires are the same

3. Late in their life, C models were equipped with FRBs.... the same as on D Models, so no changes there.

4. The pitot tube on the left side of the nose should be removed (C models only had one on the pilot's (starboard) side)

There are a few other things that I am sure that I missed, but I am sure there are others that could help with that. The cabin interior is almost identical except that on D's the Avionics closet was usually covered up as was the heater closet.

Hi Grimmo,

 Almost certainly, backdating the "D" Model due to the trailing edge of the aft pylon... but you need the early rotors from the other kit.... Hmmm...  you're going to be in for some alterations either way you go it seems.     If it was me, I think I'd backdate the "D" and deal with the rotors some other way, in order to have a crisp blunt fin in the back.

Not as many antennas, bumps, or vents either, but they would be easy fixes.

Good luck... lots of interesting things going on!

Take care,

Frank

Thanks Jonathan,

I'm aware of the great amount of work I have ahead of me. I was hoping I could "steal" some detail from some of Cobra Co's aftermarket kits.

My plan is to make a "new" Guns A Go-Go helo and then convert a CH-47A to an ACH-47A ,again starting from one of Trump's Hooks. This way I would have the "old" and the "new" in my collection.

Plans, plans ... if I only had time to make the come true!

If you are refering to the detail/correction sets that Chris Miller has done...only parts of them would be appropriate. For example the cockpit between the A,B, and C were different than that of the D, the most noticeable feature is that the engine condition levers were relocated from the center console as on As,Bs, and Cs, to an overhead location on the Ds.

The avionics closet has different components also but you could probably get away with using that. Inside the aft pylon ( and no, the correct nomenclature isn't  a "Mast" or "Sail", or any other of the names I've seen it referred to) and ramp area the Eduard set should go a long way in helping. The aft transmission is usually concealed by a three piece drip pan (that also serves to help direct cooling air entering the cut out on the leading edge of the aft pylon, past the combining transmission to the aft transmission and aft transmission cooling fan) What you will need to replicate is the Flight Engineer panel on the right hand side of the aft cabin, the three part drip pan for the aft transmission, APU and generator plus assorted hyrdaulic rigid and flex lines along with associated accumulators.

The center cargo hook for both kits is representative of those found on D models, so you shouldn't have any problems there. The "rams horn" antenna on the forward lower part of the aircraft (looks sort of like a boomerang) needs to be reshaped. There is a BUNCH of scratch building needed to change this beast into a MH-47E, for starters the fuel pods have to be redone and the forward landing gear need to be relocated, and of course the refueling probeand supporting structures have to be scratch built as well.

Good Luck, for the kits that I have in the stash, I will probably stick with an  A model and backdate the D model to a C model.

Also, check with Frank, he has some extensive info on what is required externally for this kit and for the recent Italeri ACH-47C to get them where they should have been in the first place.

Thanks for the heads up! I just placed an order for two of each set.

I currently have the A model in the works and these  will go a very long way in addressing the problems with the gaping hole in the aft pylon and lack of detail in the ramp area.

 The cockpit detail set is very nice and fits perfectly. A couple of areas that I have addressed on this build is the center cargo hook and the slightly raised area in the companion way between the cabin and cockpit as well as the vertical hinge pins on the rotor heads.
