Smoke can be a revision. As such, I'll assume y'all are down for a a biplane!
I'm not sure either, GUNIN. I think they have an artillery advantage, apparently.
Close to parity in range and power, but they have recoil compensation, so their artillery is more accurate.
Also, posting a revised plane design here.
Biplane
Essentially an unarmed reconnaissance biplane, with wood-and-fabric wings, and an aluminium fuselage that should be enough to stop the 7.62mm rounds on a glancing hit (And given the lack of any proper AA mount for their weapons, everything will only glance). A radio should also be mounted, in order for it to be able to report it's findings as they see them.
Ill give this one a +1
Looks like this is what you want! Don't count on an aluminum fuselage stopping any kind of bullets, your best bet is to avoid bullets.
Model 1 Biplane: A biplane mostly design around the heavy an awkward Model 2 Radio. Research into aluminum framing was conducted, but a good source could not be secured this year. As such, the airplane consists mostly of a wood-and-canvas frame, with pretty conventional ailerons, elevators and rudder. It can immediately be distinguished from a normal plane by the four foot radio mast sticking out. It weighs about half a ton and is powered by a new motor with six opposed cylinders. Most of its spare weight and space is taken up by the Model 2 radio, which is powered by the motor and operated by a co-pilot. Despite it not being in the design requirements, the plane comes with a center-mounted Brumby, complete with interrupter gear, and a couple yards of ammo. Maneuverability is somewhat poor. Costs 2 oil.
You may now revise.
