Good job explaining your plan in the beginning.
What an ingenious way of using an RC car to water your plants.
Very creative to use the RC car as one step in the energy transfer. That’s action at a distance!
It was good to see the drawing of your plans. Using a large RC car in the process is something I haven’t seen before.
