The Chinook's been in a bit of a holding pattern this last week. I've been held up on it whilst waiting for the CSAR hoist that Russ French offered to make, to arrive, but as I have been home from work recovering from hernia repair surgery since last Monday, I have had some time on my hands and finishing off the B737-800 didn't take as long as I expected. So I started by doing some pre-shading on the fuselage and finished painting and assembling the rotors.
Image

I was happy with the pre-shading lines, but although I had followed the colour call out for the rotors, it was rightly pointed out to me that they were too dark, so back into the office I went and laid down a new coat of NATO black, then added some grey to the NATO black, added some feathering to the leading edge, and then finally ran a very thin line of tan to the edge. This I was then very happy with.
Image

This morning I rubbed them back with some micro mesh, made up some masks for the rotor markings and sprayed the yellow lines.
Image

Continuing on, I applied the 'No Step' and rotary wing serial number stencils to the rotor blades, added some extra details to the heads and then to finish them off I dry brushed some flat aluminium onto the rotor head. Here is the result.

And here is where we're at now. Hopefully, I'll have the hoist mounted and some paint down on the fuselage in the next couple of days.

Cheers bud, yeah that coffee table is around 700mm wide and the rotors will not turn within that space.

I had to make some changes this morning due to information received overnight, to the colour rings on the rotor heads. I had seen photos of red and yellow bands in photos, but due to not seeing a complete head, did not know that the three arms each had a different colour band, red, yellow and green, and I had just assumed that the bands were dependent on what time period the photos were taken. So they have now been touched up to properly render this. As the rotors are linked to turn in concert with each other, to make sure they are aligned, when one colour band is facing forward on the front mast, the same colour rotor blade must be forward on the rear mast. As the rotors spin in opposite directions the bands go in the opposite order too. Photos to follow later this afternoon after I get home, or you can see my face book model page to see what I mean, now.

As promised.

This rotor head is a rear. As the rotors are contra-rotating, the colour band patern is reversed on the front rotor head.

Looking good Troy. FWIW, it was standard practice on RAAF Iroquois and Squirrels to colour code each blade for maintenance purposes. In the case of the Iroquois, it was red and white. Everything connected to that blade had the same colour, either a painted dot or a small band. There was a "Rotor Smoothing Sheet" kept with the maintenance logs which was updated whenever a tracking or balance adjustment was made and test flown e.g. "Red Blade Tab adjusted up 1/2 Degree". That way, if there were any reported vibration issues we could go back and check if anything had moved or been disturbed.
Cheers,
Rod C

I've been back at work for the last two days, but the last two nights have been most productive. Yesterday the long-awaited CASR hoist for the Chinook arrived from Russ French at DMA. Unfortunately, upon inspection, it seems that the Blackhawk hoist is way smaller than the one on the Chook.
Image

Image
It should be as wide as the door and a bit higher.

Image
So I did what I should have done in the first place. I began to scratch build one using evergreen square rod glued together to get the correct length, width and height. Roughly cutting it to shape with the razor saw, I then filed, sanded and carved it to a much closer shape, ten using Tamiya epoxy, sculpted the additional fairing.

Image
Much better, but still needed more work, but that would need to wait until the epoxy had cured.

Image
Tonight I sanded and filed some more, until I couldn't hold back any longer and decided, perhaps prematurely to mount it.

Image
Using some brass rod, evergreen c-channel, CA glue and Zip Kicker, I got that sucker in place. Man is it solid.

I carried out some more fine adjustment after taking these photos, mainly to the bracket mounts and the cable gland, but it's really looking great, and I'm getting ever closer now to getting some paint on this weekend.

Painting day.
Being the first time (sort of) that I have used Model Master paints, today started with a small false start, but after finding a suitable thinner in my stock (Vallejo thinner did the trick), I got stuck into painting the Chinook. The paint went down real nice, gives a nice coverage, and when thinned down still allowed for the pre-shading to come through where I wanted it to.
Image

Image

Then it was detail painting time. Taking my time and constantly looking through my references I've noticed that a lot of details have changed over the years. From colours of antennas to the configuration of sensors, there is a lot to take in, and my primary reference photos don't answer a lot of them, so what I have decided to do is go with what I think looks the best from each era. There are still a few things to figure out, but I'm in no rush.

Image

At the end of the day as the sun was getting down close to the horizon, so once more I slipped out the front to take some pics in the dying light.
Image

Image

Image

I need to go through my spare parts box and find a suitable hook for the CSAR hoist, but next up it's time to apply the clear coat and get stuck into the decals.
