I have been thinking of a wiper solution for flying in rain.
There is this awesome new FPV plane coming on the market from Asia called the 'Universeye Penuin' It has a huge clear canopy to protect the camera. But if you get rain on it .. it would really really suck. I was thinking just put a servo with an arm and a piece of sponge on it
Today I was real paranoid that the board camera would short out in the rain! I ought to make a cover for it. also my ground station needs a a clamp on golf umbrella (or maybe not - the wind might blow it over!)
