Hi guys! I've been working on an open source 3d printable modular helicopter controls set for a while and decided to launch a site with all the stuff recently. All can be built with 3d printed parts and aluminum profiles (10x10mm and 10x20mm), along with some M3 and M8 hardware. All the stuff is tested and received a significant electronics upgrade recently :)

All major parts are SS495A hall sensor based (throttles are resistor based), all wires (except UTP-5 cables connecting components to each other) are hidden inside enclosures. Everything is unified and uses a single Arduino  Leonardo as a master controller, Arduino Pro Minis as peripheral controllers, and Adafruit ADS1115 ADCs for cyclic and pedals. All the stuff uses an I2C bus to connect to each other. Controls design is not a copy of any particular helicopter but made generic to suit all we can fly (twin throttle collective is also available, though there probably will be some upgrades for it soon). I have to say it isn't in fact helicopter only; I will add some GA controls as well shortly. At the moment there's a Cessna 182 themed engine controls panel.

Here's a couple of photos of the set:




Right now I am working on a Bell 412-style collective head for my friends and a couple of improvements for single and twin throttle collective levers. If someone is interested, you are welcome! More stuff, like manuals, pictures, release files and dev snapshots is on my site, everything is also available on thingiverse.
