New flyable in 4.50 is
Beaufighter MkIF and MkINF - nightfighter version but without radar, and since CloD night has "psychedelic" illumination and planes lights, searchlights don't work, this NF version is just curiosity.
Franken'Moth - one version for "alies" and one for "axis", both armed with single forward firing MG for very slow "fun4all" (?) doghfights over Isles of Doom MP map or maybe that "inspired" Cross and Roundel map...
New "flavors" of existent planes:
Hurricane MkI FB - a "field mod" with rack for 8 x 50 lbs bombs
Bf 110 C-6 - with under belly pod with 30mm cannon
Blenheim MkIV Late - with turret with 2 MG and rack for 50 lbs bombs on wings.
