I find it very difficult to believe that they are so busy being innovative that they don't have time to drop a quick note on the forum. They once had a regular presence here, and I fear that they still read the forums from time to time, but don't have anything to say.
There was talk about gps firmware updates coming with improvements in all aspects of performance, but despite reading about summer dates and hearing any day now during phone conversations nothing is being said.
I like the pro flight controller and liked the gimbal board before going brushless, but I'd have a difficult time investing in another product of theirs based on failure to deliver on promises.
