Recently picked up a new E-flite Carbon-Z Cub. Set up the model as in the manual, and it flew very well as expected. BUT- I thought it needed aileron to rudder mix to turn better. I did this in the Tx as I had done with other models before and it became virtually unflyable, removed the mix but it still does not fly very well. Have I upset anything in the A635 Rx. Any advice would be welcomed.
