I am trying to program a DX6i and bind it to a FMS 1400mm CJ3 Cub. I programmed the TX according to instructions in the manual with the aim of making the Cub easier to fly for a beginner. I made the minimum dual rate 70% for Elev, Rudd and Aiel and set the EXPO at plus 15. I took the Cub out for a test flight and immediately after lifting off from a grass runway it became extremely difficult to control with the result that I crashed and am having to replace the landing gear. I can fly an E-Flite Apprentice set on beginner mode and I can fly a Mini Micro T28 fron Hobby Zone so I thought I could fly the cub at those settings but I was wrong. Please tell me what the Dual Rate and Expo setting s should be in order for me to be able to handle the airplane. Also any other programming I should do to the DX6i ? Thanks
