A solution for the phantom 4 not being able to fly full speed while using tracking mode. It's super annoying. Anything I want it to follow goes way faster than 20 mph.
All flight functions are essentially vetted by the on-board software.
So called Fly-by-wire.
Until the software can be user configured for such 'solutions' there won't be any.
In this case it may be more of a computing power issue since that is limited or finite in this product.
