RE: up dated batts from 4.8 to 6.0 now have a problem
do you have any extensions on the rudder servo, three things will make a servo overshoot 1. too many extensions on that servo 2. a dirty or wornout pot 3. a analog servo that is older cannot keep up with the speed of the signal, newer analog servos and corelss servos seldom have this issue, this is noted on the hitec and airtronics support pages
