I have an H-160 that was working properly until the prop was jammed by a foreign object. It blew a fuse which I replaced and now it runs as soon as I connect the battery. I tested the reed switch and disconnected it from the electronics and it changed nothing. Any other ideas where to look for a problem?
 
Eager to dive it again I took the controller out and a friend suggested one of the FETs was likely bad, they tend to fail short circuited. I de-soldered both FETs and replaced one that tested bad. It now works. It was a $2 fix plus a few hours of my time.
