So i was playing warthunder and my favorite plane type are attackers, so i decided to make my own

V1

Ordinance: 4 500 pound bombs, 2 1000 pound bombs


V2

Guns: 4 47 mm guns

Ordinance: 2 500 pound bombs, 1 500 pound bombs and 10 rockets

V3

Guns: 8 .50 cals and 1 75 mm at gun

Ordinance: 6 500 pound bombs, 3 1000 pound bombs

now I'm not sure how powerful of engines they would need or how large they are. So feedback would be much appreciated
