OV-10D Bronco ~ USMC (WIP)

To really get started around here I thought I would start a build log and share in my latest project.

The OV-10D Bronco from Academy in 1/72nd scale, a very unique and different looking aircraft and, as such, one I’m very interested in. Rather than model the desert camouflage as seen on the boxart I thought I’d go for something a little different that I found on a Desert Storm website. It’s a Lizard style camouflage scheme, three-tone and wrap-around that I find very striking.

The kit is very well detailed which I would expect from Academy but unfortunately there are quite a few sink marks about, especially around the cockpit. As far as I can tell Academy have taken their OV-10A boxing and added additional sprue for the D model, which makes sense. I had a close look at the two AIM-9 Sidewinders included in the kit and I’m pretty sure they’re older AIM-9D’s rather than the AIM-9L’s in use during the Gulf War.

Onto construction and it starts with the cockpit as usual. You’ll notice some of those sink marks I mentioned above. I’ve test fitted the cockpit together and the two sink marks that I’ve filled are the only two anyway visible once everything is closed up.

There are more sink marks on everything you see here, although for some silly reason I’ve everything turned over when I took the picture. Most of these pieces go towards making the cockpit and so I find it a shame that there are so many sink marks in that area. The ribbed section is part of one of the wheel wells which is another bad area for sink marks but it really shouldn’t be.

That’s an interesting aircraft, and a very nice model, too. I made the vietnam variant once, you can see it on my web page here. Please take closer look at the engines, somehow they are totally off in the model, the undercarriage also could take some detailing to be accurate. And you have to start early planning for the nose weight, it takes a lot of lead to make this machine stand on its own, althought this variant’s long nose makes it somewhat easier - but still you have to watch it. Good luck with your project, have a nice day

nice subject… cant wait to see it finished. Ive always been a fan of the OV-10. I just wish someone would come out with a better offering one in 1/48 That or someone would start producing Paragons cockpit set for the Testors one again…

I’ll be interesting in seeing this come along. I, too, like the OV-10 and have that same kit.

Nevermind 48, I want to see one of these in 1/32 scale. The detail possibilities would be incredible. And it isnt such a big plane that 32 scale would cause a lot of storage problems

Very cool! I did not know they flew Broncos in Desert Storm…

Desert Storm was the last great hoorah for the Bronco, and only the Marine Corps deployed em. The USAF retired em in 91 and the USMC in 95

Both the OV-10A and OV-10D were deployed by the USMC to Desert Storm. As far as I know they used it for FAC duties and observation.

Unfortunately the A model was lacking in IR countermeasures and so several fell victim to shoulder launched SAM’s. If you look at the boxart in the first post you’ll notice a red lantern shaped object on the back of the OV-10D, that’s an IR jammer.

The USMC had to rush those in and fit them to the OV-10A’s to give them better protection.

Alright guys, I’m going to need some help here. I’ve been looking through Google Images and Flickr trying to get together some good images of the cockpit for the OV-10D, although I’d settle for an OV-10A, but I’m not doing very well.

Most of the pictures I’ve found are of Broncos in fire fighter service with some extra gadgetry added to the aircraft so not very helpful. So if anyone can dig up some good images of the Bronco’s cockpit I’d be more than grateful. I’m particularly interested in the seats, harnesses and the rear of the cockpit.

You can see some OV-10A cockpits photos HERE…I’ll see if I can find some D model pics for you…

Looks like that craft is being restored, so those pics aren’t ideal but they are something. The only D model pics on that site are from the exterior through the canopy, so again, not ideal. Sorry.

EDIT: ANOTHER PIC HERE

Ive been searching for years hoping to scratch build something… anything to put into testors 1/48 kit. the best Ive ever come up with is a few pics of converted forestry service birds. Not accurate at all fpr what your trying to do.

Thanks for the replies guys, those pictures will help a great deal. They’re the most detailed I’ve seen yet.

Whattaya want to do with it? I’ve built a couple of the HAWK/Testor’s Broncos… If you talk to me back-channel about it, I might have a few ideas for ya, once we get into specifics, as far as materials and scratch-building cockpits go… (It’s kinda my thing, detailing those old kits…)

Apologies for the lack of updates lately, I’ve been trying out a few experimental techniques for making small aircraft display bases while I contemplate what exactly to do with the Bronco cockpit.

I’ve been working away on the cockpit of the Bronco for the last while. What Academy provides is fairly sparse and for the OV-10A I suspect. I’ve tried to add some detail where I could but super detailing, or whatever you prefer to call it, isn’t really my forte. I don’t have the patience to carefully cut and shape aftermarket styrene.

I’ve only got the one picture to show, it was getting the dark as it was taken which didn’t help and the gloss coat has made everything look pretty dull. It looks better in person I can assure you and should look even better once weathered.

Some additional detail I’ve added include seatbelts made from green putty, they’re a little on the thick side but once weathered and viewed through the canopy I think they’ll look good. I also used green putty to add padding to both seats and I used it yet again on the front sidewalls to put down a few buttons. Academy left this area bare and I felt it needed something. There is a throttle lever there on the real aircraft but I couldn’t replicate that. I added a black box to the side of the front seat as there seemed to be one on the real aircraft. I’ve also added another box to the top of the rear console and I’m going to paint a screen on it.

Finally I noticed that the Bronco has an abundance of cables snaking through the cockpit. I desperately wanted to recreate that as I thought it would look impressive. I first tried simulating the cables using strands of picture hanging wire but it wouldn’t bend the way I wanted it too and the super glue wouldn’t hold it down. Odd I thought as it was holding the wire to my hands pretty well. [:S]

So I settled on thin white thread. The thread was dipped in future and left to dry before ‘installation.’ You see when I get around to weathering the cockpit I want the wash to pool around the thread but not stain into it, the future should keep it safe. Also the wash could’ve caused fibres to splay out of the thread which I also didn’t want. It happened when I tried to paint un-futured thread, terrible looking.

The plan of action is to build a shelf at the back of the cockpit, another thing Academy neglected to add, and run the threads into a box. Hopefully by the end it’ll all come together. It’s not something I’d been too keen on jumping into again.

By the way, I’ve made a small display base for the Bronco using a tea coaster and some sandpaper. If you’re interested here’s a link to the thread at IPMS Ireland.

Another update with loads of pictures too.

So I’ve closed up the fuselage halves and thankfully the seams on the tub aren’t that bad but I’ve realized the Bronco is going to have lots of sub assemblies so there will be seams aplenty soon enough.

You can see what I was trying to do with the thread here; I made a ‘fuse box’ of sorts out of green putty with the idea of feeding the threads into it. I don’t think the effect was really pulled off very well. In fact once I started weathering the cockpit the thread stained, as you can see, which I didn’t really want. I’m just hoping that once the canopy is on it’ll all come together.

The weathering was done with a Citadel wash, Babab Black in this case, and then a matt coat followed. The shelf the fuse box is sitting on is a piece of evergreen; Academy provided nothing for this area and there would’ve been a hole into the fuselage visible through the canopy. I still need to block up the back of it.

So that’s the cockpit, certainly not the best I’ve done but it’ll do I think. I might add some brake lines to the landing gears later in the build so if anyone has any suggestions for a good, and easily attainable, material for brake lines then let me know.

Weight is going to be a big issue for this build, I can tell. Academy suggests about 8g for the nose but there’s absolutely no room in there. So I’ve added to two fishing weights immediately behind the cockpit and I’m hoping this will place weight just forward, or on, the main landing gear. I might be able to squeeze some one cent coins into the tail booms just behind the props to add in more weight.

You can see a few seams here on the underside of the fuselage tub. The indented area accepts the weapons station which will create more work as its fit isn’t great. The fit of the nose to the fuselage also isn’t great.

And here is the weapons station; the grooves in the front accept the OV-10’s guns which are M60 machine guns. I thought I read somewhere that some OV-10D’s had their M60’s upgraded to 30mm cannons but I’m not sure. I’ll be leaving the guns off until late in the build to make sure I don’t damage them.

The OV-10 has long 40 foot wing and the kit wing comes in two pieces that need to be joined together with four small holes drilled out first for the wing pylons. The middle gap at the back of the wing slots over the fuselage tub while the other two gaps accept the tail booms. As far as sub assemblies go first I’ll need to add the weapon station to the fuselage tub and clean that up. Then I’ll add the wing to the top of the fuselage tub and clean that up. The tail booms will be assembled, and cleaned up, then attached to the wing and, again, cleaned up. Lots of seams and gaps to look forward too. [:^)]

Finally the weapons loadout for the Bronco. Moving from left to right there are two LAU-10 rocket pods, an LAU-68 rocket pod, a 150 gallon fuel tank, an AIM-9L Sidewinder and a wing pylon launch rail for the Sidewinder. I took the loadout information from the Desert Storm website I mentioned earlier in the build blog.

The three rocket pods came from the old Italeri NATO weapons set, two of which I bought recently from eBay. The Sidewinder came from a Hasegawa weapon set and the fuel tank plus the wing pylon are from the kit.

So the next big job is to get the sub assemblies built and start joining everything together, then the Bronco can really start taking shape. There’s a lot work involved but it’s worth it for a Bronco in my opinion, great looking aircraft.

Now, let me ask everyone one last question. Considering the amount of gaps and seams I’ll be facing what is everyone’s favoured method for dealing with them?

Looks like you are making some pretty good progress.

good work!

looking good :slight_smile: just curious though, shouldnt that weight be further forward? I would imagine that where its as will cause it to be a tail sitter?

I had the same problem with a BAe Hawk a while back; the nose cone was far to small to put weight in so I put two weights just behind the cockpit, over the main landing gear, and it prevented it from tail sitting.

I’m not sure if that’ll be sufficient for the Bronco, the tail booms do make things more awkward. Someone suggested dicing up lead sheet or wire and squeezing it into the nosecone, I just need to track some down.

In the meantime I’ll build up the tail booms, attach them to the wing and then dryfit everything the fuselage tub with the undercarriage in place. I can work out the weight requirements from there and if the two behind the cockpit are causing problems I’ll dig them out.
