I couldn't go out much because of the corona, so I was thinking about playing together outside, but I remembered the radio control I was doing when I was a kid, and I tried to let my child do the radio control I was doing. I bought it.
However, when I was a kid, there were only a limited number of places to run nearby, and I was frustrated because I couldn't take the plunge, so I entertained the children in an environment where they could race to their heart's content. I want to give it.
I made my own circuit in the vacant lot in front of my house.
Originally, I'm not good at thinking about DIY and hand-making, so I'm not good at it, but I'm up to the completion of the circuit. In addition, I would like to mention things related to radio-controlled models, albeit little by little.
