I see some very impressive stuff going on in here!
I've been enjoying the new A2A Spitfire, which is far and away my new favorite add on, beating out the RealAir Spitfire. Being able to change fuel octane, canopy style, and swap from variable to constant speed or fixed pitch prop is really cool, and I actually enjoy the simple fixed pitch more, which saves something like 300lb over the constant speed prop. I also took the guns and ammo out to make it super light. With the 2 blade fixed pitch, 87 octane, and open canopy it really has the feel of a late 1930's style of plane, which is a unique experience.
