I have a project coming up where every servo (6-8 servos, depends if I decide to add flaps or program flaperons) will have no less than a 3-4ft lead and possibly up to 5-6ft for the aileron servos. Other than going up on wire size from the standard 22 gauge to 20 or possibly 18, do I need to increase the voltage? I planned on using a castle 10A BEC to power the receiver and servos, but I don't think it has the ability to select between 5 or 6 volts. Do I need to look into other BEC options that can handle the amp load (all digital servos) that can output 6 volts to counter the expected voltage drop across the servo extensions? I planned on desoldering the leads off each servo and soldering the new extensions straight to the board to eliminate connections and any "bottle necks" going from 18-20 gauge extensions to the 22-24 gauge found on most servos. What about adding capacitors to the extensions close to the servos, would that be more efficient than just throwing more voltage at it or should I do both for optimal performance (6V and capacitors on the servo end)?
