I think its the linkage or something, I flew it today, it flew well but when you make a left turn it does not center back, it stays in that left turn tilll you give right. I made right rolls and it centers back to middle fine from right just not left.

I think I am going to try a 6v battery in my RX and see if it helps, and maybe figure out the linkage some more, but it did fly well, after my knees stoped knocking not been that neveors flying new plane in long long time, but wasnt sure it fly with wing insidence and all.
