As far as I know, the premium F-35 sabre, which just went on sale for 4th July, is identical in performance to the F-25 and F-30 sabres, which both sit at BR 8.7 in sim. The F-35 however sits at BR 9.0, which is the same as the F-2, which has the great 4x20mm cannons.
In RB, these 3 sit at the same BR of 8.7.
If there’s a reason for its higher BR in sim I’d love to know, or if not, lowering it to 8.7 like the others would be great.
