S!
Andy, the FM's have been changed, to the better from stock hands down in most cases. Ironically Bf109G-2 got least modification as it actually is closest to RL data. Biggest changes were in FW190, there was a lot done as the Kommandogerät was basically non-existent in stock FM etc. It should be remembered that the modded planes are in new slots, stock ones are not touched. And in a server with modded planes they are pitted against modded ones to keep the balance. Look at 1940 BoB servers, damn fun fights with a Bf109E that actually can fight a Spitfire Mk.I and not just be the caly pigeon
It is about looking at the whole picture, not just at one plane
DM's are stock, nothing done there. The 3D models have been fixed from the legoblocks to look like a Bf109 or the cowling and other things fixed in the FW190 and also allied planes have got lot of new stuff. Look at the P38F and G for example
Brilliant planes. And as of modders..look what is coming to 4.10..a mod called MDS
So the co-operation is already there to implement the best of them to official releases, which is like in the old days. Certified by Oleg so to say.
