I've been away from the Arducopter community for around 2 years now. I never got the early APM1.x to work stable, so I've been using other FC's the last couple of years.
Do you think the newest Arducopter is a stable/solid solution now? Is it advisable to trust it for professional use with expensive equipment and cameras, or does it still have "bugs"? I will, of course, test the system extensively, but I would like your opinion before getting involved again.
