DIY Passive & Active 4WS Controller

[Hydrocarbon92]

I finished my V1 4WS controller last year, but I've been working on lots of additional ideas. The main idea was to allow me to program & save settings, then it gave me the idea to program how much rear steering % for each mode.

In this vid it's ~5% for FWS or "passive 4ws" and 100% for full 4WS & RWS, but I'm also using a shorter rear servo arm. Usually RWS needs less since it really flings the rear end when moving fast. Together with the wp1080 I can move this Wraith to each corner of that little platform, parallel to the long sides.

I also added in programability via a little dongle with 4 buttons, but it became too limiting. Next I'm going to configure it to change mode based on the potentiometer/dial. My stretch goal is to add bluetooth so I can program it via my phone!
