[MOC][PoC] Coaxial Rotors with variable pitch

Recommended Posts

 

 

 

Hey, everyone,

À couple years ago @Sheepo built his amazing Kamov KA-32 helicopter, whose highlight (IMO) was that the rotors were coaxial and with variable pitch. While here I didn’t want to replicate the other mechanical intricacies of what Sheepo made, I wanted to build coaxial rotors with variable pitch, as à simple interpretable mechanism. So here’s what I came up with:

I actually made this video in July (not deviating from my TC12 entry for now :laugh:) but wanted to share it while I was in the process of building big, long MOCs as à sort of side thing. I want to start making more proof of concept models, but haven’t really gotten the time to, so I’m kinda proud of this one!

If you have à comment, would love to hear. Thanks and have à nice day!

Lego would not use that, because of friction on the axle from many locations. It would slow down, and burn up the clutch gear.
