Mosquito FB XVIII : we have no uboats for it to attack. It would be unhistorically used to hunt bombers, IMO. It's a bit of a corruption of history to want this in the game as we stand now.
Re2000: Only 170 built, and all served non-Italian forces (it was an export only).
Re2001: Only 252 built of which 150 were specifically night fighters. Impact on the war was minimal at best.
Re2005: A non entity. Less than 50 built, grounded until the tail could be kept from ripping off, and by the time it was ungrounded Italy was out of the war. It wasn't a front line plane, and you could debate that it wasn't even a production plane.
P-51C: 100%, absolutely identical to the P-51B, but given a C instead to denote it was built at a different production plant.
C.714: So woefully inadequate that everybody that had even small numbers (not many were built) removed them from duty before WW2 really started. They were unreliable, underpowered, and obsolete. Only a Polish squadron or two flew them after being ordered to stop, because they literally had nothing else to fly. Really one of the most obscure planes in WW2 and not even worth consideration.
Do-17: Obsolete before the war, even during the Spanish Civil War, this plane was the weakest and slowest bomber Germany had to offer. By the battle of Britain, it had very small numbers in the fleet and those numbers were all but wiped out before it was withdrawn from active duty entirely. It serves no role in AH (not even in scenarios) and would have no role outside very limited BOB participation. This plane is a nonentity also. Better to request He-111, or Ju-88A-1
IK-3: Never made the war. 6 built. Only 20 ordered before Yugoslavia was invaded. Where are you getting these from, even??
The above planes shouldn't be part of the poll.
Your only real suggestions are:
Beaufighter
He111
C.200
Z.1007 (although why this instead of the SM.79 is a mystery)
Ki-27
P-51A (this should be A-36, instead)
