A few other threads are discussing 109 performance and issues, so I won't go into a whole lot of detail here. Lets just say that opinions vary on the loss of the G-10 vs the gain of the G-14 and K-4.
One thing this 109 fan would like to see is the 109 K-6 with the 2 x 30mm Mk103 gondolas and the DB605DC (2000hp) powerplant.
The 109K-6 might make a good "slightly perked" variant, like the Spit XIV or the F4U4. The best of the series, so you ante up a few perks to fly it.
I think it will definitely add to the "pucker factor" on both sides of a bomber interception - facing 3 x 30mms is brown trousers time in the bomber, but it doesn't take too many .50 cals to be able to laugh at the spiraling death of perk points either.
I would also like to add my kudos to HT and the gang for the 109 cockpits - I think they are excellently done and definitely add to the game.
