RAMs PBR 31 Mk.IIs

I though about that, but to fit the Jerry cans you have to modify the ammo can tray (basically cut out the bottom & back & fit the Jerry cans permanently). Then the only way to use the 100-rnd cans is to try to balance them on top of the Jerry cans, at an angle, to feed right - pretty precarious on a mount that can swing violently & erratically to change targets during an engagement.

Well dang. Guess you'll have to go with the 100rd boxes then. Unless...there's a way to replace the cut down jerry cans (a set of pins hold them in place, pull pins, swap cans?) then you'd have to have several sets of jerry can reloads near at hand?

I've found some 3D printed resin .50cal flexible feed chutes in the stash (& ordered some more - from these guys, Black Ops Models, out of Sydney).

After all, there's room under the turret for the old twin-.50 tub, which had two trays of about 1000rnds per gun & the space no longer occupied by the gunner. So my idea is 4 x trays of 1000(maybe 1200)rnds feeding the quad-.50 through flex-feed chutes coming up through the turret floor - at 600rpm that's about 2 minutes of continuous firing without the need to reload.

The guns look great! So do the instruments.

Thanks, Frank!

Thanks for the info. I do have some LR M240's and Legend makes some FN-MAG's/M240's as well which I have but LR is better quality and has better details. Great job as always and waiting to see the quads mounted on the bow.

Like the Owen gun.. nice touch

Niiice ... I had totally missed that Owen gun! (I was fixated upon your open-breech M79!)

Great builds and awesome detailing.

Says the King of Functioning Scratch-Built Detailing ..... I'll take that as high praise!

I think the 3D printed resin that the .50cal feed chutes are made of has beaten me ... For the moment.

It takes more effort than ordinary polymer resin to bend &, when it does, it can take two or three re-heats with it clamped into position before the bends hold.

Then woe-betide you if any heat gets near the bent area again, as it flicks straight back to being straight! 


So, tomorrow later today, I'm going to clean up the workspace, put the PBRs aside, & find something else to build, a plane, which fits into my vehicle/watercraft/aircraft cycle.

Thanks for confirming my suspicions about the resin issues and difficulties encountered. 

I sought out an alternative in the form of 1/32nd scale ammunition feed chutes made from a rubbery material that was included in the large scale Trumpeter aircraft model kits like the P-47 Thunderbolt.  Not the perfect solution but definitely a better option than what you are dealing with.

Apparently, that sort of form-memory 'hysteresis' is really hard to design in to plastics. Unless you don't want it there, I guess?
