I left the radio on all night and killed he lipo. I installed another lipo and the polarity in he connector was wrong. Burnt smell came out so I figure a fuse blew out. There are no fuses in these radios but I did find a blown cap. Cant tell what size/type it is since it burnt pretty good. It is C1 on the board and there is what appears to be one like it on C2. I would hate to have to replace the entire board if the cap fixes it.
Any ideas?
