(...) Connecting the motors in parallel means they'll get 16volts at about .25amps each. (if their combined electrical resistance is right, which it isn't, which makes the solar panel perform badly...) That's 4 watts per motor, when they're intended (...)

You will also gain some efficiency by simplifying your gearing since the new motors are already geared (...) (22 years ago, 15-Feb-03, to lugnet.technic)
