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?
