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 ) 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!

Hello all. This is my entry for the [TC5] competition: Helix, a Police Helicopter with intermeshing rotors. This build is a combination of 42002 and 42020. and After some trial and error, this is what I came up with: Functions: - Spinning rotors, controled by rear rotor - Retractable landing gear, controled by grey axle connector on the right Optical: - Cockpit with seats, steps and instruments - Flashlights on front and back Build: The angle for the intermeshing rotors is created with both the pin connector blocks. Almost all gears in both sets are needed here to create the intermeshing rotor system. I also wanted a retractable landing gear. It has seen several build, but the final system is an easy but realiable sliding system. (controled by the grey axle connector). Testing: Testing of this creation is done by my two year old daughter. She loved the spinning of the rotors. No bricks were harmed during testing. Will add more pictures later. Cheers or comments most welcome. Thanks for reading!
