This is strange, I have a Revo. 3.3 that i converted to electric a while back. I only have 5 runs on it when it was still a nitro. I never drove it through water or anything and i 100% sure that no oil or anything has gotten on the screws. My revo has been sitting on my shelf for a while in my room and it has never came into contack with moisture. Yet some of the screw heads have some rust on them. I am not worried about it, I just dont know why they have rust on them. Has anybody els had this happen?
Even my Slash 4x4 has rust on the screws and i have never driven that through water aswell. I dont know what is the cause. And how do i remove the rust?
