I just had my first solid hovers (entire battery).I read an article that suggest that you limit the aileron throw for beginners.Since you can't do that on the cp tx,I instead drilled out the next hole in on all three servo arms to 3/64 I think and relocated all three linkages to those inner holes and flew the bird successfully.However I couldn't get out of ground effect, so next I took the linkages loose from the blade grips and unscrewed them 1 full turn,and voila, I can fly and reasonably control this bird.
