(...) No, it only has one pin hole, and no axle holes. Why LEGO decided to do it that way I can't imagine - all previous sets (AFAIK) used the offset axle holes (present in the old 24t gears) to connect pistons, not the pin holes. IMO that part is a (...) (22 years ago, 7-Feb-03, to lugnet.technic)

Question: Since I don't know what the z24 exactly looks like on the prop, is it just like the regular gear? Reason I say, I'm curious, because you could use the holes on the gear to pin another z24 to it and then you'd have a place to mount another (...) (22 years ago, 7-Feb-03, to lugnet.technic)

I have this part (from <set:8855>) and I have been unsuccessful in my attempts to power it to any significant speed. The problem is that the prop and z24 gear are permanently molded to a 3L axle which goes through a 1x4 Technic beam. Having only one (...) (22 years ago, 7-Feb-03, to lugnet.technic)
