AM (1hr) hydro car

We connected the pipes by following the manual guide, but it was another model and since it was clear, it is hard to follow. We then tested which main components does what by unplugging and plugging the connectors while steering: found the small cube is receiver and signal and it also works without the hydrocar (same speed). We were curious to know if the hydrosticks fuel the battery or acts as an accelerator. We plan to layout the parts and then tape them down next time.
