This was actually a cancelled tactical cargo version from the OV-10. It never got from the drawingboard though. But what if it actually happened?

This is the starting point:

So instead of widening the OV-10 fuselage I choose to use a Do-28 fuselage as it comes in about the right dimension.

And I've STILL not finished it!

And see the Flight Simulator version of it too, a wonderful looking machine and it 'flies' very well too.

Ah, I didn't know you're also doing an OV-10 variant. I guess yours is more true to the original concept as the Do-28 fuselage is a tad too wide and too long (probably).

Maybe an updated version of the original variant (with more payload).

Alas, we'll see if I 'm able to finish this project in time. I'll try to keep you posted.

The Do-28 fuselage is now in a sink cleaning fluid ( NaOH) to strip all paint. Later today will be neutralized with cola, than will be and put in water to dissolve the cola remains.

It seems a shame to waste cola for neutralizing a strong base. If you feel a need for a  mild acid, you could use vinegar, it wouldn't leave sticky remains like cola.

LOL, I had a similar idea a whiel ago when I mounted an AH-1 cockpit onto an OV-10. Curious how this works out, because I am afraid that the wider hull will either interfere with the propellers, or the stabilizer has to be widened to adapt the span (and respective prop clearance) to the wider hull?

'Doing' isn't the word I'd use David, more like 'Did'! It's been YEARS since I did any work on the CV-10, it stalled on the lack of a proper canopy so I'll be interested in seeing how you get on using the Do-28 fuselage as a basis, at least it has a canopy to start with. 

You build might trigger me into getting on with it at last too.

Cheap cola is cheaper than the equivalent volume of cheap vinegar.

Time for a quick update:

The fuselage of the Do-28 was cleaned. The subs for the wings and engine hangers were removed and puttied to smooth out. Wings will bet put on top of the fuselage and a little more to the rear. The rear of the fuselage was cut (tail section out) and the bottom of the fuselage was kept to be angled upwards to fit a re-contoured rear fuselage. The old matchbox plastic was a tad brittle so heated the bottom of the fuselage before bending it upwards.

Found out the wing of the Academy wing has a wider fuselage than the Airfix one..

The wing will be cut and in the middle a new section ( from the Airfix OV-10) will be put in to widen the wing over the fuselage. Same will te done for the horizontal tailplane.

Congratilations David!   (and Kit, and maybe Dizzy).
It is wonderful you extend the Bronco family with personnal additions!

 

That's looking VERY promising. 

That looks very good. I assume that the OV-10T will receive a nose landiung gear, too, with the main wheels in the booms?
I really like the new shape of the pod/fuselage's end section - might even offer enough space for a ramp?

Sure it'll get the normal nose gear, tailbooms and maingear. It will all be transplanted from the OV-10 but wings and tailplanes will be made a little longer to fit the wider fuselage.
There is a possibility to fit a ramp in the rear but it's of no use as the fuselage isn't wide enough to fit a jeep (I think, need to check). There is a big door in the left rear for entry of passengers and para jumping.

I have read somewhere that one of the reasons of the twin-boom layout, for the OV-10 design, was the use of a rear door with full access to the fuselage section, even if not enough for a vehicle. I do not guarantee this is true, but this has been mentionned. Of course, this could be the same, and even more, on the cargo derivative.  

The standard OV-10 had an opening rear to the fuselage pod because it could carry troops inside, albeit not many. I see no reason why a CV-10 shouldn't have a ramp at the rear because the real one was intended to have just that, see the FS version in the pics I linked earlier.
