S!
Well, Bf110C with DB601N engines/C3 and Bf109E-4/N using C3 are not modelled in game at the moment but no-one is complaining

Bf110C with 100oct would be easily faster than Hurricane and faster than Spit at some altitudes, but still no-one is whining for them, even they existed

Will be added if devs deem it OK based on data supplied to them. No need to make a drama out of it at all.
I flew red on ATAG and damn that Spitfire Mk.Ia 100oct and Spitfire Mk.II are easy to fly, even with slightest grasp of retaining E with proper maneuvers the Spits eat Bf109's for breakfast. The view out is best bar none and handling so forgiving, saw a lot of Bf109's spin out of the sky. Sure CEM caused a bit of problems for me but initial impression of Spitfire was pleasing. Sure maybe not up to speeds and all that but it can hold it's own easily with a competent pilot
