I think I know the answer to this but I'd appreciate a second opinion before stripping down...
Fah Pah ArduCopter kit, ready for first flight, everything working well except occasional 'clicks' from motor(s), can't tie it down to one motor in particular.
I've changed out the bullets on the motor side and are nice and tight now (they were all loose), wiggling wires doesn't seem to have any effect...I didn't change the connectors on the ESC side.
I've attached a mp3 of the clicking, if someone can listen and tell me if it's normal or not that would be a help.
If not normal I'll replace the connectors on the ESC side and get the the Power Distribution board out and have a look at the Deans etc - anything else that I should look at?
Many thanks, Paul
