I know there are plenty of guys using Mikrokopter with their trusty Cinestar frames. MK announced their new FC: Flight Controller V3.0: http://wiki.mikrokopter.de/en/FlightCtrl_V3.0 * Navi Ctrl is now integrated into the FC. * Integrated camera controls * 6 servo outputs * Redundant flight control system is now fully integrated * Up to 7S support * A new version of GPS is available also: V3.5 * GPS is now connected to the main FC with a better cable. Old 10 pin standard ribon cable was just a pain. Mikrokopter is concentrated on mapping, inspection business where waypoint and extensive camera controls are a must. I am not sure if they come up with a new BL controller. As of 2016, I would expect at least 12S support on this new FC since we have some very efficient motors which runs on 12S. No words of flight performance. I'm sure it will fly the same; since MK flies very well already. Is it worth upgrading? For me, definitely no. For aerial videographers, I can't see any new feature set which we will benefit in practice.
