Give your excavator the ability to work on the railway by adding a pair of rail axles.
The rail wheels are spaced to run on OS-Railway track printed at 200% scale.
Connecting this to the standard control PCB is an unknown as my build uses my own custom control PCB (which I do plan to release in future). I believe there aren't enough motor channels to run everything but you should be able to hook up some external motor drivers to the spare servo connectors.
This remix also contains modified versions of the lower body and main boom holder that give more clearance above the tracks and move the slew pivot further back. These changes are intended to bring the model closer to the proportions of a real RRV, they are entirely optional.
Required hardware:
- 2x the same threaded N20s as the rest of the excavator build
- 2x double shaft right angle 12V 60RPM N20s
- 8x 3mm LEDs (4x red, 4x white) for directional lighting on the rail axles
- M2.6 screws of various lengths
- You will likely also require a slip ring with more wires
