| | | | Yes, I had tried that. I was unable to prevent all the rotation at the friction pin, and even a small amount of movement there caused significant wobble/binding. Mark Haye "Ross Crawford" <rcrawford@csi.com> wrote in message (...) (21 years ago, 7-Feb-03, to lugnet.technic)

| | | | | How about inserting the 24T gear into half a large turntable, and securing the other end of the turntable using axles. I know this gets very large where you don't want to get large, but it might provide stability in ways the other solutions do not. (...) (21 years ago, 7-Feb-03, to lugnet.technic)

| | | | (...) Well I did a little test, heres the pics: (URL) that the propeller shaft is cylindrical, not "x" axle-shape, so friction is much greater than standard axle. It worked reasonably well, even with no lubrication and old batteries. I reckon with (...) (21 years ago, 7-Feb-03, to lugnet.technic)

| | | | | (...) Nice design. Oh man, the design of the 24t gear at the back of this propeler is realy lame. That whole part is very un-legoish. 1) Perhaps you could use the old friction connector instead of the new one: i.e. part 4459 instead of part 2780. (...) (21 years ago, 8-Feb-03, to lugnet.technic)

I still get what I consider pretty poor performance (with (...) (21 years ago, 8-Feb-03, to lugnet.technic)
