For the sake of organization, I'm putting together a votebox so we can keep track of what's out there. Still not voting yet, in case any other revisions pop up.
Revision List
Barnett 1916 V12 'Swallow' Engine
Incandescent Ammunition Revision
Lesser European Swallow Manueverability Improvements
Barnett Weight Reduction
Sky Crusader Armour
JTT Penetrator Aerial Munition
Bull's Eye Aerial Gunnery Ring Sight
So comments/critiques/nitpicks down the line so far.
Barnett 1916 V12 'Swallow' EngineGot to keep pushing that V12 hp. Nice technical write up too.
Incandescent Ammunition RevisionThis is the tracer revision we desparately need. Incendiary rounds are a good stretch objective too, especially because the KPAF somehow made them effective in a rifle round caliber. The only nitpick I have is that the incendiary bullet placement pattern in the belt looks ugly AF. I can't find a pretty way to make 5 or 10 work either, so why not 1 ball, 1 incendiary, 1 ball, 1 tracer? We'll just keep our ammo counts in multiples of 20 rather than 10.
Lesser European Swallow Maneuverability ImprovementsSo the LES kinda flies like a brick with its metal frame. Taking out the over-engineered struts is probably not a bad idea. Could use more detail on what to do with the control surfaces though. Maybe make them bigger? Add some kind of mechanical advantage (levers or pulleys) so the pilot can crank them harder? Do we have rudder pedals yet?
Barnett Weight ReductionYes, dropping engine weight would improve the thrust to weight ratio, but you don't say how. Which engines parts are we making lighter and how? How will that balance against engine performance too? Feels kinda cheap to just throw that at the GM and make him figure it out.
Sky Crusader ArmourHmm, as much as I loved NAV's original Sky Crusader Armour, it was timed for winter warfare in the mountains. It's literally summer right now, so the timing is a bit off. More importantly, just like last time it's getting derailed by having another revision stealthily shoe-horned in, the parachute. An eight item clothing loadout should be its own revision. (Do we get all eight items? Do they even work? Do they fit pilots of all sizes? Are they hot, itchy, or otherwise uncomfortable? Are they durable? Are they expensive? Are they demoralizingly ugly or pridefully badass looking?) I think it's obvious a Heinecke-style chute like the KPAF have really should be a standalone revision.

JTT Penetrator Aerial Munition(This one is mine.) Dirty jokes aside, this could bag us a destroyer this turn. Hopefully that'll sway the Navy some more for the autonomy push. To recap, the smallest aerial torpedo ever to get a kill was 800 lb, still not powerful enough to take a warship solo, and we're nowhere near that payload-wise,
https://en.wikipedia.org/wiki/Short_Type_184. (Those torpedo bombers could also only fly in the tranquil Mediterranean because they were basically overloaded and couldn't handle Atlantic winds and distances.)
Bull's Eye Aerial Gunnery Ring Sight(Also mine.) A cheap way to try to balance the air-to-air gunnery fight this turn. Also a hedge should we misroll tracers again.
Not revisions, but for the sake of completeness...
AD Truck proposalWhy is this still a thing? Our V12 is probably too good for this. Seems like a waste to develop a truck chassis and presumably a hand-crank operated quad gun turret we'll never use. The Army is happy with the Motor Partnership already. If you really want to economize on dice for the HMG, remember we can also bundle in incendiary ammo, disintegrating link belts, maybe twin-gun mounts, and probably better sights. It's an end-game weapon so I'd rather get it perfect now and never have to tweak our machine guns further for the rest of the war.
Kingfisher proposalI love it except for one nitpick. The Crossguard-enabled front gun is unlikely to see any use. The plane is by design unmanueverable, so it would never be able to line up a shot in a dogfight. A Foster mount might see some use because it can swivel some, but it's really the tail gunner that's going to be doing the defensive shooting. I'd either cut that front gun entirely, or at least downgrade it to an actually more useful Foster gun.
