The Yuneec drones, meaning the Q500 and the Typhoon H series, were very good in their day. I have a Q500+ 4K and still consider it to be very capable, but it’s not portable in the same way the Mavic series is. I liked it at the time because it wasn’t just another Phantom Clone. I’ve no experience with their Mantis series of drones but when they were released they were a year or two behind their DJI equivalents, meaning the Mavic range, and we’re probably in part responsible for Yuneec’s decline.
