I'll be posting a bunch of final renders in the coming days.

Grey with LAU 33s - makes it VAL-4's 155494. Why no nose #?

It's a CAD image, the grey is just plastic representation. Everything is grey (props, tires, ordnance, etc) except some brass color showing photo etch in the cockpit. It's not meant to show a scheme.

Sorry for the delay. Not only was ARC broken but Facebook locked my account for several days until I sent and they verified a picture of my face. :angry:

Pavlov? Pavlov who?

No. Pavlov is not a very common Chinese name...

Outstanding job on a subject desired by a lot of modelers and sadly overlooked by manufacturers.  The CAD looks magnificent so far!

 

I am curious.  The list is probably a mile long of subjects desired by modelers and sadly overlooked by manufacturers.  What motivated you guys to say OV-10!  Let's do The OV-10!

 

i ask because sometimes the motivation can be as interesting a story as the endeavor itself.

Happy to hear that you like what you've seen so far.

Sorry, but the background of the choice is not exciting. The Bronco is just what the boss wanted to do first (well, Su-33 was first but that went South...).

looks great for the most part. the second to last shot though has the rudder pedals on the side consoles rather than on the floor.

Seat on the right (without backpad) is the pilot's (front seat). Seat on the left (with backpad) is the backseat.

Drag on the parachute pack that is on the back left side of the front seat would make the seat go to the left on ejection.

And the back seat would go to the right.

OK - a poser. System won't let me upload another photo so use the one above.

Centerline tank with aircraft on ground has a slight nose down angle.

If you look at where the fill point is you can tell that it is below the tail of the tank. How do you completely fill the tank?

The pedals in the observer's compartment are in the correct location.

Perhaps one of the Bronco guys can fill us in on why they are located there.

I'm also curious about the fact that the rear flight controls (flap handle, control stick and pedals) are listed in the NAVAIR manual as "optional". Where they ever not installed?

I was curious as to why they are opposite. Thanks for the explanation!

So many nagging Bronco questions the more I study the plane...

Do you happen to know if I got the latch and ring answer correct in this post? http://www.arcforums.com/forums/air/index.php?/topic/296183-148-ov-10a-bronco/&do=findComment&comment=2853273

Actual plane was a lot more streamlined than the fourth picture indicates.

I'm not exactly sure what you're asking here.

If it is in regards to the rivets/fasteners, we are limited by molding technology so have minimum sizes that can be molded.

The flush rivets have to be molded as engraved details. A finely engraved flush circle done to scale isn't really possible and would disappear under the thinnest coat of paint.

The detail will be as petite as our tooling will allow.

 

I didn't realize how prominent the fastener detail was before starting this project:

Good question. Something I hadn't even considered.

Rear filler cap?

Or is they some fancy hydraulic system to jack the nose up that I'm not aware of? 

Park it uphill when fueling?

:dontknow:

Stunning job on the CAD design by the HazMat team Chris! Will the tooling be done by the same people as GWH MiG-29/Aviation Art Su-33?

Hi Chris,

Great project by far. It's gonna be a real stunner being plastic cast...in case the molds are as such as the 3D-modeling shows.

I'm not a 1/48 scale fun but this kit will be an exquisite stuff I would eager to have in my stash.

Well, I think I'd better go and take my bib to drool. :)  

 

Cheers!

Alexander

well I stand corrected. they look like they would make flying the plane almost impossible.

Just a comment on CAD models. CAD objects are used to control CNC machines that will cut steel (moulds) or copper (EDM electrodes) so one can only partially extrapolate how the plastic will look like from a CAD rendering. You can have a idea of the shapes and detailing but nothing more as the CAD model is a collection of abstract objects. CAD renderings must be taken with a pinch of salt as...

- a CAD model is scaled (thickness of parts and details level depends on scale) but the rendering software allows to zoom in the CAD model infinitely close while you cannot look at plastic parts infinitely close; 4th photo makes the model look like it's a 1/10 scale model but it's still a 1/48 scale CAD model

- objects of a CAD model have razor sharp edges and corners; this isn't the case with plastic parts where corners and edges are always a little rounded as the tool tip hasn't infinitely sharp edges and corners; EDM process also doesn't allow infinitely sharp details

All in all the CAD model is an intermediate phase in a model kit design. What matters in the end are the plastic parts.

That is exactly the point I feel about CADs and why I never get very worked up about them. For me it's the end product and sharpness of molding. Fitting of the parts and assemblies is very high on my "want list". I will wait for sprue shots before I get closer to purchase decision.

Yep, door hold open assembly. I've got the Air Force version of the "Illustrated Parts Breakdown" on the Black Pony webpage - http://www.blackpony.org/ipb.pdf

Thanks much Laurent - I'm not a modeler and didn't know.

No hills in the Mekong Delta. Nothing in the books about it - so the North American Tech Reps told us to throw a line over the booms, loop & tie it loosely and sit on the rope to pull the nose up. In actual practice - we walked up to the nose gear facing aft, placed a shoulder blade under the fuselage - and straightened up lifting the nose until the gear extends & locks, place chock behind wheel and it would stay that way until your done.

Accuracy matters a lot to me so the CAD design phase is very important to my eyes... still designing a kit is like making a chain link by link. A weak link and the whole chain integrity is compromised. Reference material has to be reviewed, CAD model has to be reviewed, parts breakdown has to be reviewed (ease of build, tooling cost), toolshop has to use machines that match the specs (very complex and intricate CAD model require high precision so very expensive machines for tooling), moulds have to be designed to avoid injection issues (short shots, etc), care is needed to design helpful instructions, box should be sturdy enough and box art attractive. And the ETA should be predictable so that the company can recover the invested money.

A related/unrelated kind of question: has anyone done the research to determine the markings of Marshall Harrison's OV-10 as written up in his book "A Lonely Kind of War"?  Especially when he was flying where there wasn't supposed to be any US presence (i.e. Cambodia).  I'm assuming some sanitizing was done (national markings, etc) but I've never seen it confirmed.

This thinking that the tooling is somehow very loosely based on the CAD has to stop. It is nonsense. Other than technical restrictions for the details, what you see in CAD - is what you will get in plastic. Thinking the CAD is loosely related to tooling just gives excuses for the modelmakers to make mistakes and modelbuilders to make excuses on modelmakers behalf. Mistakes in CAD will be reflected in the plastic. There isnt some magic gulf between the CAD design and the final product.

 

Hobby Boss Su-34 mistakes are not some wish-washy result of CAD being "collection of abstract objects" or technical limitations. Spine and wheelbays in Su-27 kit isnt wrong because of that either. Or the nose/canopy on MiG-23/27. Zvezda's (and HB for that matter) T-50 doesnt look like it does because CAD's are some sort of random sketches of the final product. All the mistakes in those kits are mistakes in CAD because of lazy/shoddy work by the design team. Not some technical limitations of the technology. If Hobby Boss can tool thin panellines and rivets - then they are obviously not limited by the tooling technology when MiG-27 nose ends up looking as it is.

 

These excuses of "don't complain about the CAD's, the product will look completely different!" are just that, excuses.
