hi, i have a question, has anyone had a problem with the elevator being flaky, when i pull back on mine, the plane acts like, starts to pull up and pauses then goes into a weird kind of turn, i replaced the servo with a new 100 oz. one and the same thing happens, it seems as though the elevator may not be flat totally and i think that would make the plane turn out on pulling back, but would it give it the delay feeling thing, any help would be awesome, i have checked the radio all out and linkage is perfect with no flex, thanks jb
