Something changed in 3.6. When I setup a plane using my same parameters from 3.5 I don’t get enough elevon throw when I pitch and roll the airplane. The TX response is fine. Just the autopilot response is too soft. I have Mixing_Gain set to 1.2 (the max) and it’s still too soft. I can set Mixing_Offset to 1000, or -1000 and get good aileron throw or good elevator throw, just not both.
Reverted back to 3.5 and elevon throw is good.
