We just had the largest flood in history. I quote an Australian defense force soldier, who was in the rescue response team, "Ive been to Afghanistan, and Iraq, but the damage done by this flood is something new"
Both my golden motors are solar charged and powered through mud, storms with rain so hard that it was almost cutting my face, they operated totally submerged at times and continued to operate and help me through the toughest times that the weather could throw at it.. I must of rode 50 metres through the water with the motors totally submerged at times, before I decided to turn back and try a different route home.
I can provide some pictures of the floods.
I don't seal my motors air tight, I just restrict water getting in as much as possible and never allow them to stop running when submerged and they seem to work fine in flood waters.
