It's just that according to this page: (URL) the new style lego motors' efficiency is only 54% at 9v (or even 47% for the 'newer' (?) style V9 motor)...which is not even close to 90%...Of course that test may be a little off, but would that (...)

| | | | (...) Well, I can't argue with that... But in your application, going from a motor with 30% efficiency to one with 54% efficiency will help a lot. 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)

(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 (...)

| | | | I've got an updated and now compleded .ldr file of the car. (except that the .ldr model doesn't have any wheels yet...ahh well, just imagine the 8880 wheels on it :) ) It's got a revised gearbox layout that uses one gear less than before, but has (...)
