I wanted to know that the motors for dagu wild thumper are waterproof or not because I am thinking to further upgrade thumper to a amphibious vehicle
That sounds like a cool project. The motors for the Dagu Wild Thumper are not waterproof, and I do not know where you might find some that are. If you manage to convert your Wild Thumper to an amphibious vehicle, we would love to see how it turns out!
