@claudius62 Yes, you're right that the PX4 platform didn't support curves. However, there is active development in this area (Commits to the code base in the last month), so it's quite possible we will see it in a future firmware update. One of the reasons Yuneec went for a PX4 controller was that they could benefit from a larger development community who're adding a range of features that they should be able to integrate relatively easily. The codebase for the Typhoon H was reputedly a rats-nest and very difficult to develop without breaking things. Yuneec don't have a huge software team, so complex code can be badly delayed if it needs changes - as we've discovered.
From what I've been told the H+ uses a completely different code base, developed by a different team. It's not PX4 based, but a custom flight control. So it doesn't do complex missions including actions at waypoints, it doesn't have programmable RTH thresholds and so on. It will do curved cable cam, but you won't be able to control exactly where photos are taken. It should be much, much simpler than the PX4 Flight controller + DataPilot, but it will be able to do 'consumer' things well. We'll see how that works out when the H+ arrives.
