A client of mine and I custom mounted a FLiR Vue Pro to his Phantom 2: Zenmuse H4-3D. After numerous balancing issues we got the setup to function nicely. The first few test flights went fine but on the most recent startup I got a miniscule puff of of smoke from the power con board mounted underneath the bird. Upon immediate power down and a closer inspection it looks as if something on the power con board "popped" like friggen Pringles lid. (See attached) Everything else seems fine. Any thoughts guys?
