Fischertechnik Liebherr R938 with bluetooth remote

Build the new Liebherr kit (2025) from fischertechnik, however instead of yellow/black bricks, I used the black and white bricks. This set is originally hand operated by switching the pneumatic valves by hand. I have converted it into a bluetooth remotely operated excavator, by using the orignal fischertechnik magnetic/solenoid operated pneumatic valves. Installed a slewing motor. All functions are connected as per ISO operating pattern.
