Ho Mark, This presents a significant problem. I always engineer my
gear-trains to include a double "axle grab" on both sides of a gear so the
gears flow smoothly. Without that extra stud worth to help anchor the
Airscrew, yep could be a problem. But not to worry, If you sandwich gears on
top if the Airscrew's z24 and then drive it with another gear below, it
should stablize it. However, it's just theory and I'd need to experiment
with it myself. Still you make a good point.

| You inspired me to tinker a bit, but I am still unsuccessful. Putting gears around the z24 to help stabilize it is problematic because, at standard LEGO distances, there is sufficient space between the gears to allow the z24 (and the prop axle) to (...) (22 years ago, 7-Feb-03, to lugnet.technic)
