The two I have are the 5625's and no, I have not tried to adjust deadband as I don't have the programmer. Seem's sorta silly to have to spend that much money to just get the servos to work properly. I heard over the weekend from a pattern flyer friend in another state that he has tried to improve servo operation with the programmer. He reports that even after reducing the deadband to its lowest value the servos still are not up to par for
precision aerobatics. Bummer.
