Is anyone else having an issue with this? I first thought I could not switch between flight modes because I hadn't gone through enough lessons. I eventually figured out changing controllers helped some. Then HH Support provided a document which shows how to take an existing Spektrum option and edit it into what I need for the DXs. I was only partially successful with various things I try. I can't get the channels above 4 to setup properly. It is my opinion that HH as the integrator of the E-flight Habu, the Spektrum DXs, and the RealFlight Trainer edition should have ensured a controller option for the DXs. In doing so, newbie's like me would have more confidence in the setup and learn proper habits while training. Anyone else running into this? Help please.
