 | | Lego solar car —John Henry Kruer
|
| | | Hello, all. I know I don't post here much 'cause I'm more of a space fan... but I just wanted to ask you all for some help. My 8th grade science teacher assigned us a project in which we have to make and race a model solar car. So, because of my (...) (22 years ago, 19-Apr-03, to lugnet.technic)

With so little power one wheel will have enough traction. The axle that holds the one drive wheel should be (...) (22 years ago, 19-Apr-03, to lugnet.technic)

| | | | Though worm gears are okay for gearing down, they're bad for friction, so in this case I'd stay away from them. Also check out this page on the charateristics of various Lego motors: (URL) for wheels, larger wheels have lower rolling friction, but (...) (22 years ago, 20-Apr-03, to lugnet.technic)

| | | | Ahh, thanks guys. I've tried larger wheels, and even though they look funny, they work the best- a lot better, even now in late afternoon. And I've added more torque using a larger gear, which makes it more powerful. (URL) digital camera movie (...) (22 years ago, 20-Apr-03, to lugnet.technic)
