I also heard tha some servos can chatter a small bit, but I thought it was around center???
I only have a few Hitec digi's on 6v, not on the "Do" but none has chattered yet..

Well getting ready to head to the field for a "Do" check .... Should be fun, that is if
my fingers don't get frost bite at the present temp of 41degs and no wind @6am
