Name (amps) [torque]
Hitec HS 50 (0.2) [8.3oz] {smaller than HS55}
Hitec HS 55 (0.19) [15.3oz]
Hitec Digital 5045 (0.28) [13.4oz]
Parallax Futaba S148 (0.56) [?oz uhm, more than those- a standard size servo]
a multimeter hooked in line using a modified servo wire ( red wire cut so the meter could be in line). The servos were operated in their functional duty : Lifting a rocket tube or moving a 4 unit-train of cars. None were 'stalled' so these measurements have only a relative context.
Locomotive Power


has a voltage spike twice the normal voltage : ? to 'bump' the locomotive? i dunno, it was a SHOCK to see it :(

PWM servo signal was of course just spikes of voltage and varying in voltage level, the variation due to the length of the signal variation 'adding' up to different levels i guess
Motor controllers : ? TBD ? investigate the output waveform ... hopefully a level voltage that will change IAW the desired voltage.
