Helicoptery Weather Vane

Managed to get this to work, which was cool. Main and tail rotor gearlinked, 1:2 ratio. Print in whatever, this one in PETG. A 608 bearing would be desirable for the pedestal, the other 4 could be 608s, but I used the printed bushings(below) to good success with a bit of lithium grease. Will need to make sure the shafts are worked in/sanded, etc so they spin smoothly before you assemble. Spring 2023 am trying one or maybe both gears printed in TPU, see what it does for gear train noise. → Generally successful, quieter, smoother running. Will incorporate TPU gears in future projects.

Make sure the gearteeth are free of imperfections. Mount the front tailshaft bushing first, then the back. Insert the tailshaft and mount the secondary gear. Next, install the bottom & top mainshaft bushings. Slide the main gear into pl
