Hi, all, I was planning to make a pneumatic front shovel excavator after buying 42053. Combining with the pneumatic parts of 42043, I'll have enough big cylinders for the excavator. It will be a pretty big one and fully RC is a good choice. Since this contest forbidding using PF other than driving the pumps, I chose to build a smaller one using the V1 pneumatic parts. Planned functions: 1 x L motor for pump(s) 2 x V1 big cylinders for the boom 1 x V2 thin cylinder for the stick 2 x V1 big cylinders for the bucket tilting The number of pumps and how to open the bucket are not decided yet. I aim to build this: Liebherr R9800, but it may end to a smaller type since that will look more proper at a small scale.
The current progress: Advices are always welcome. Thanks for watching
