RE: Servos for 1/4 scale WWI?
Not all hi torque servos have metal gears and I agree with Dave that the metal geartrain is as important as the amount of torque maybe more so. Also a good point on switches, the first time I had a switch fail it was sort of in slow motion, I would check the batt state with an ESV post charging and over a period of about a month it seemed to me like the battery wasnt coming to full charge then one day I checked after a charge and the power was way down so I unplugged the batt and tested it direct and sure enough the batt was fine and the switch was building resistance as time went by. I use the big JR switch with the charge port built into it and at 20 bucks I swap them out every couple of years.
