Combatpigg did use the term "field wiring” which I presume implies the requirement to connect wires in battle fields. I would assume using Ken’s technique for proper good soldering procedure would be a luxury battle field conditions don’t provide .Nevertheless our hobby equipment are just as that; for hobby use and reliability standards are way below mil specs. Probability to have a servo malfunction is a lot higher than even a semi good soldered wire joint. IMHO
