In reference to balanced control surfaces - Does a small part of control surface in front of hinge line aeodynamically reduce torque needed to move control surface? Does the amount of force reduction correspond to the ratio of the areas/moments? Does mass balance refer to placing a weight on the small part in front of hinge line?

I have heard that using 6 volts requires use of a voltage regulator because the fully charged battery may be over 7 volts. What is risk of burning out servos/receivers with 6 volts? I enjoyed your comments last year about CG on weightless/overweight planes. I constantly have the same problem in my professional field because I get better results when I ignore convention.

I will check out the calculators later, but for now off to work to pay for digital servos.
