The Throttle kit allows you to build any combination of levers and trim wheels. I have included some editable parts in the kit meaning you can extend the levers allowing these units to be used for bigger quadrant builds, such as 747, or whatever takes you fancy. The lever ends are matched to the Saitek/Logitech quadrant size, this allows for any other 3D project handle system to be used with the Throttle Quadrant Kit.
In the kit I have added handles and levers to build a DC3/C47 style throttle Quadrant, and a PA28 arrow throttle quadrant. There is also a twin handle boat throttle option. The kit is designed to be interconnected to aide with stability, and the parts allow for various combinations and lengths to give your own design an easy starting point.
Each potentiometer has a braking system to allow the throttle friction to be set and forgotten about, and of course if these brake units wear down you can always print a few new ones. Please note the tolerances on these parts is crucial, and to ensure a good fit the sizing may require a little wet dry sand paper allowing for the variations between printers.
Parts required:10k linear potentiometers 7mm or 10mm collars, as requiredM3 x 30 bolts with Nyloc nuts, as requiredEncoders
It is assumed the user of this kit has some basic electronic and mechanical understanding, with some basic soldering skills. Having said that, it looks like a lot of wiring, but it is just three wires repeated for each lever. I’m not going to go into the wiring, but just offer the links to the relevant websites.
Leo Board BU0836x www.leobodnar.comIs by far the easiest of all the boards to use as its point-to-point wiring, plug-&-play no drivers required.
Freejoy with STM32 board https://github.com/FreeJoy-Team/FreeJoyWikiFreejoy is my personnel favourite, it’s a bit more complicated than the other options, but once you get your head into it, it’s awesome. You can build a tailored made plug-&-play device for as little as £7/$10
Mega 2560 and Mob flight https://www.mobiflight.com/en/index.htmlThe Mega 2560 is around the same prices as a Leo board, and requires either a good understand of Arduino coding or you can use the fantastic piece of free software Mobiflight.
Whichever controller board you go for, the build process is practical the same.
