Have you ever driven a racer in the rain? This is obviously not recommended, at all, because electronics are not friends with humidity. Yet with components entrenched behind a fairing and a bit of insulation, it is possible to drive even if the weather decides otherwise. There remains another concern: in the rain, with a racer, the drops of water on the FPV camera are painful! You can try using products that prevent water from settling on a surface, but that doesn't work very well.
The solution ?
It was imagined by Dima Tsvetkov. His name means something to you? Remember, he had proposed propellers to be printed in TPU! (see here). Its assembly is quite simply a wiper for racer. It is based on a servo, an arm and a small brush. The magic of its editing? He included the instructions to integrate manual or automatic scan to radio controls under OpenTX! The Lens Wiper, a good joke or a really usable project? It's up to you…depending on the weather at your location! The description of the project and the files to download can be found on Thingiverse.
