I noticed the same problem. It's like when I fly this plane knife-edge for a while with enough speed, I can find a sweet spot where it hangs around without too much AOA, but if I feed in just a TAD more rudder, it drops the tail a lot and sits in a high-alpha configuration, just stuck there. Whassup with that? I'll try the NACA 0013 on the fin!

On the other hand, the Extra 330 is one sweet plane on the sim! I can get this thing to do ANYTHING!


PS: Confirmed. The airfoil Knife-Edge chose for the edge is a real problem. NACA 0013 is much better. It flies like a plane now.
