Here are the pulleys with the belts, but pulled slightly out of the transmission housing. The lower drive pulley works the larger drive shaft which is the inside propeller. The upper pulley is the inside driveshaft for the outside propeller. Note the belt for the upper pulley is crossed. This creates the counter rotation. |

I couldn’t let the counter-rotating transmission go! I realized that gears wouldn’t work, but what about belts! I re-designed the gears into pulleys and thought I would use rubber bands, but couldn’t find anything small enough. Then a friend at work told me he had some filament for his FDM 3D printer that was very flexible and stretchy. He let me borrow a spool and I printed out the belts. They worked okay, but didn’t grab well, so I also printed out the pulleys in the same material and it worked like a dream! |

Had to remove most of the former ahead of the cockpit. Now it fits where it should. Have to make a canopy before putting the 2 instrument panel in. lds |
