Maybe I should explaine it a different way........The problem lies i'm 90% sure with the 605 sevos (in retrospect i've had a few to many 605's go bad, all on 6V)...I'm pretty sure that the 6V battery combined with the 605's was a potential problem.... I checked out the receiver on another plane and everthing normal....however, I just got the 9C and haven't had the time to delve into the book for the 2 seperate elevator servos...it may seem simple to you because you know how but I haven't got that far yet but I plan on spending some time on it tommorrow because i'll have time...thank goodness for Fridays!! I've never had a problem like this one in 20 years of flying and instructing and don't anticipate having another like it....happy flying...Dave
