About 2 months ago I purchased fly sky radio worked really well but than indoor came around. I took all electronics out and cleaned up my truck. After I cleaned it I put all the electronics back in and than the esc would not work which is a 100 a hobby king one. I failed the self test so I put the stock receiver in and than it worked so I figured it was the receiver. I got the receiver replaced and still don't work any suggestions? I tried in a rc18 to and still a no go
