i havent used my revo for about 10 days (on vacation), and when i came back i charged the battery and went to turn the reciever on and nothing happend. i turned the swich off and tried again and again and it finally kicked on. i drove it an hour later and had to do the same thing. i got snow on it before it left but i hit it with some wd-40. but could the water be my problem. when i ran it, it worked fine. it was as responsive as normal. why would it be doing this?
