i used a smartfly regulator switch on an aircraft, he recommended using a 2 cell lipo. the extra voltage of the 3 cell creates more heat that needs to be disappated (did i spell that right?). on another aircraft i used a MPI miracle switch (not enough check rating for all the digital servos here though). i also used an rcreporter for electrics (rcreporter.com), it gives an audible voltage reading on your lipos. i appreciate your list here, i am planning to set one up similar.
