For those looking to do a scaleorama cross of a 1/72 V-22's nacelles with a 1/48 Bronco, I'd recommend the Hobbycraft 1/72 V-22 kit as a suitable donor.  The engine nacelles bear a passing resemblance to the real thing but certainly don't reflect EMD or production configurations; making them highly suitable for whiffing use.

Another one I did a while ago:



And yes, I know it still appears to have the fuselage engines...consider this a prototype econversion.

If you slimmed the tip pods down to just the rotor then the roof engines could stay put.

You could follow the line down from the top of the intake to the top of the exhaust outlet.

Civil Tilt-rotor


Civil Tilt-rotor to V-22 comparison





Regarding an OV-10 conversion, personally I'd have the wing section outboard of the booms
rotate with the new engine/rotor assemblies. The reduction in under disc area would probably
be advantageous in VTOL mode.

Yeah, I dd think of that...may yet do for future variation.

... Bell finale.






75 passenger transport, note that the third pic is of a version with a V-tail and canard like the CTR-1900.
Evidently this configuration had the least drag.

D-326 looks like a big brother to what is now the Agusta A609 (formerly Bell-Agusta BA609).  One of the more interesting ones is the D-300 which was an iteration toward what became the XV-15, it looks very much like a long MU-2, with the short MU-2 main gear, with the XV-15 wing (appropriately enough, the Aerophile article on the XV-15 shows that Boeing's entry was based on using a long MU-2 fuselage).  It's a temptation to get the resources together to model that one.

One thing I've always wondered about these is whether they can fire any wing-mounted weapons with the rotors in plane-mode? I bought an Anigrand XV-15 with the intention of bashing it with a lot of AH-1W parts. I'm still wondering how to mount the weapons. Could you fire a Hydra 70, TOW or Hellfire "synchronised" through the rotor?  :o And if you can't, wouldn't it be a terrible waste of energy to have to go into hover mode every time you employ your weapons?
My solution is to use the wing for drop-tanks or bombs only. Anything powered will go on pylons down the fuselage sides, with slightly chopped rotor blades.
Cheers,
Moritz

Hmm, just a thought but I could see that CTR-22 in the markings of FedEx or other express companies (DHL perhaps?) as well as various other cargo carriers.

Had the chance to go out to the experimental hanger and look over the V-22 we're working on.  It looks like the LH sponson could be stretched forward to fair into the fuselage in line with the windscreen frame; this would give you room for a small weapons bay or fixed gun mount.  There are, too, provisions for a nose-mounted gun turret under the radar but I don't think that option has ever been exercised.

For other possibilities, how about an AEW radar mounted on the aft ramp much like what the FAA has on Sea Kings now?

Under-fuselage?  I doubt it as it sits pretty low to the ground.

Ramp mounted radar sounds like the best option considering how low to the ground the aircraft actually sits in real life.  Unless you increase the length of the landing gear to make the room available. 

The stretched sponson sounds interesting.  Or at the very least, an excuse to kit-bash the MatchBox/Revell Chinook with an Osprey.

Yeah, the fun comes on the RH side where you need to work around extended sponson around the main door.  You could probably still do a fairing ahead of that, though, or just mount external stores racks there (being careful to keep clear of the rotor envelope).  I wonder if the Apache's TADS/PNVS turret could be adapted to this use?

Gents, This last week I've been trying to find 3-views of this subject for a scratchbuild and have reviewed my old bibliography of Boeing and Bell's aircraft, googled to death and zippo, Nada. I have even tried to manipulate an XV-15 3-view to no avail. Does any of you.....? ;)

I think your best bet would be the issue of Aerophile magazine with the XV-15 as the cover article.  Since said issue is 30+ years old, good hunting.  Methinks your best bet for now would be using a scaled V-22 fuselage and tail (with Kingcobra cockpit and nose) coupled with what's now the AW609's wing and engine nacelles.
