Hi all, I have recently assembled a set of Randy’s rudder pedals. They come with motors for for/aft movement. To use the For/aft toggle switch on the MIP we need to build a device using two DPDT Relays. The Jet45AAS / Systems Modules Document has a diagram of the wiring required. This is my initial construction using two common plug-type relays. It’s a lot of wires all over the place.. This is just the relays, no toggle switch wires or power in & out wires. To make my life a bit more neater I have designed a simple PCB to eliminate all the wiring. It has two HK19F DPDT relays, diodes to minimise back EMF, and a whole bunch of connectors. It also has the option of adding external limit switching if the motor you are using doesn’t have it built in. Looks like this when connected: Much better! The external limit switches are activated by connecting your limit switches (NC) to the two screw terminals labeled ‘Limit Switch A’ and ‘B’, and removing the PC pin jumper located at the inner corner of the screw terminal. The completed board is ‘plug and play’. I have a few spare PCB’s and components if anyone is interested. You need one per motor. I can supply a kit version for US$20 per board or fully built for US$30 per board, both+postage. Send me a message if you are interested. Nice work Will! We need all the help in the world to make our projects a little more neater and organized. Things like this definitely help! I already have mine wired up but if I didn't, I would certainly go this route. What you have designed is exactly the same thing as what I have wired up except your design is more compact. From what I have seen, the motors all come equipped with internal limit switches which protects the motor from running deep into itself and damaging itself. The external limit switches will be needed to protect our pedal assemblies from damaging itself. Unless you find the "sweet spot" and set up the placement of the pedals perfectly, external limit switches will need to be included. And it does not hurt to have extra protection. Great work Will!Dual Rudder Pedal Assembly
