I suppose another option would be to do a faired in Gepod approach with the ammunition wrapping around the gun:

I had originally thought of using one of those, the problem with it is the chin turret I have under the nose. I don't want any interference between the two guns so the GAU-8 has to be positioned higher than the bottom of the fuselage. I want the chin turret to be operational when the GAU-8 is in use.

The drawing you've attached though, gives a good idea how long the barrels and breach actually is, about 3 meters or 9'-10"

What about mounting the turret under the middle of the fuselage. Could still fire in every direction.

I thought about that too kerick, but then with the prop-rotors in the forward flight mode, the gun would be restricted in where it could be fired without shooting the blades off (and that's even by shortening them as I have). At the moment I have it so it can fire in around a 200 degree arc, that's forward and off to the sides. By positioning the GAU-8 in the front of one of the sponsons, it's clear of the blade tips by quite a margin compared to the V-22, which has the blade tips passing very close to the fuselage sides.  I found one of those Gepods in my stash, I'll post a pic later to show the size difference between it and a sponson.

I would use the GEPOD but fair it into the front of the sponson.  This would put the muzzle pretty much in the same position as the rockets that were trailed a little while back:



It would also be conceptually similar (though neater) to this:

OK, the idea is not to go the 'arming the V-22' route, which is why I'm shortening the prop-rotors but adding more of them. The idea is to make the equivalent of a Cobra compared to a Huey. For what it's worth, I don't like the AC-130 type of gunship, the Cobra seemed to me to be what a gunship should be so that's what I'm attempting here.

The Gepod is quite a large bit of kit, but here's a comparison of a 1/72 Gepod alongside my sponson. You can see the A-10 GAU-8 barrels and fairing that I removed from the A-10 kit, glued to the front of the sponson (top pic). I've positioned the barrel ends about where it shows in the drawing shown in Greg's posting. The next pic shows the sponsons to the AV-22, which is a big aircraft. As big as an A-10 really ---

The prop-rotor blades are shortened enough that they clear the sponson, although until I get the weapons bay doors done, I think only the inner ones will be able to fire the RP's in a head-on attack.

If you go back to Post #11, you can see how the sponson will be orientated. The bottom half of it has the weapons bay and wheel bay, the top half was to be fuel tanks but I've since changed that. The photo I posted of the barrels/breach and the ammo drum shows some interesting details, it looks like the gun is just bolted down by the brackets it shows. So as the sponson has a mid-point shelf (so to speak) the gun would be bolted down to that.

Sorry, I don't mean to ruffle anyone's feathers, and I know everyone is trying to offer helpful advice, but the plan is to make a modern day Cobra.

Note that a production version of this would have pylons for gunpods (small), rocket pods, or missiles on both sides though there are dimensional limits; for ex. you could only have a double rack of Hellfires, adding a second pair below them isn't possible without hitting the ground when on the gear.

I forgot you had the A-10 fuselage on this.  Looks damn fine.

I thought I had posted these pics but apparently not --

Top one shows where I cut the whole top off the V-22 fuselage. I then reduced the width so it would fit onto the A-10 fuselage. Also shows where I cut out the main wheel bays.

Second one shows how I had to repair the A-10 fuselage after it broke totally in half.

Next two show where I reduced the width of the wing center where it goes over the fuselage. Once I had glued it to the wing box which is part of the fuselage top I then filed it to match the curved top of the A-10 fuselage.

It appears I either forgot to add photos to reply #25, or the pics went missing. It would explain why I thought I had posted pics of the repair work. I've fixed the reply with the appropriate photos

A couple of other pics I thought I had posted -----   ???

Top one shows I've finalized the nose gear arrangement and how the orientation on the sponsons but without the wing in place.

Bottom one has the wing in place.

The main gear is straight off the V-22, the nose gear is a combination of the A-10 strut and the V-22 oleo and wheels.

What I wanted to have here is space beneath the fuselage for a fuel tank, an F-15 size one. Or it could be for a MER and some smart weapons etc ---
