Hello all,
the winches, for digging two RB35:100 and one Maxxon gearbox-motor to pull the boom.
the cab was very difficult, today i would build this parts in copper
For operate i'm using a Graupner F14 (40MHz), 12Volt plumbum battery and 4 controller Thor 15, two of them will switched between winch- and driving motors, radio controlled over a little servo.
Best Regards
Wolfgang
