:( I have been trying to get the new Edge 540 to fly more like a 40% Carden and have come upon an annoying problem.
When in Knife edge the tail wants to drag and won't straighten out when you release the rudder stick. It just hangs in a high alpha position for a few seconds like the servo is stuck :mad: .
It's not the transmitter box (latest G2 Interlink) as it works fine with the "Extra 330S 3D".
Any suggestions ??? :confused:

:D Ah Haa eurika !!!!!! It was the airfoil shape of the vertical stabilizer. NACA 0013 seems to work very well.

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.
