I haven't tried it in-game yet, but i doubt it will have variable flaps.
Especially seeing how the controls behave differently for every aircraft depending on what it actually had in reality. For example, pressing V to lower flaps in the 109 will only result in a small turn of the wheel that manually extends them: you have to keep the V key pressed until they extend (so the 109s isn't really better off in terms of combat flaps deployment, i tried it and it takes ages).
If you press V in the Ju88 it works completely different, a lever is moved from the "neutral" to the "down" position: as long as the lever stays there the flap motor keeps running and flaps keep extending, so you don't need to keep pressing the key. You just need to press V once to start lowering them and then press F once to bring the lever back to the neutral position to stop them.
I don't know how the Spit works because i mostly fly around in the 109/110 and Hurricane, but with so much attention to individual aircraft characteristics i seriously doubt the Spitfire is going to get a preferential treatment.
You can also probably forget the dweebfire nickname, with full physics settings ALL planes i've tried in the simulator are a total bitch to fly compared to IL2:1946

In the previous IL2 series there was one way to model everything for all planes and operating limits where almost non-existent, obviously favoring the aircraft with the better performance by simplifying their handling and operation.
This one however models everything almost down to the bolts and rivets and there's a dozen ways to kill yourself or mess up your plane without even getting close to the enemy.
