Go back into the setup for the servos. Make sure your travel is correct. You may need to change channel directions in the radio. I dont know for sure because I never setup an ikon.
Before mucking around in the fbl initialize the fbl. Double check your inputs, left is left right is right and up is up. Next check that correction directions are correct. Lean right swash tilts left vise versa. Do that with elevator and rudder also. Then go through and make changes as needed.
I dont kniw your model so I would also check what kind of control you have, leading edge vs trailing edge. Being align my guess is leading edge on the head.
