I assume you've gone into the Aces High setup, select joystick, and assigned the axis to each and every stick axis. Don't forget to assign brakes to an x y axis on the pedals, as well as the standard x y axis for stick.
Get every axis, You should see three CH Control Manager Devices. On the left you should click on each AH Control item, then click the CH Control Manager Device in the middle, then click the appropriate Joystick Input on the right, then don't forget to click Set Input, and Apply, for each and every axis choice.
Test them out in the calibration blue screen section of AH. If you find you have assigned them to the wrong stick, such as the rudders are moving the throttle, then go back and assign them again until you get it right.
Again, don't forget to assign the right and left brake.
I hope it's as simple as that.
