this one , that one. which one?
OK, the FW currently in the module is by Goebish which can set the video ch but only has Hubsan protocol. The previous one is by Midelc which has both Hubsan and Flysky protocol.
Before the updated ersky9x I tried with Midelic it will bind but no throttle on hubsan, crazy rear motor on v959.
Today with updated ersky9x, I am using Goebish, bind with pulsating motors.
I think this may happen to the Multiprotocol module I am going to make too. unless Midelic did some change in the communication protocol.
I prefer to be able to set video ch so I can use my goggle. Actually, I just went out and flew with ER9X and Goebish using my goggle, only I have to carry extra battery to power goggle - I don't have a Futaba port on my ER9X tx. and it is kind of too quiet, cause I don't have sound on ER9X Tx

But boy, this Hubsan 107D is really good at flying FPV, the most stable one out of my 3 micro FPV model. The range of the video is only about 80~100 m though. Need to do some mod as some suggested to increase the video range. At 100 yard no issue with the A7105+Goebish of radio control. Actually I lost video a couple times, by remembering orientation and brought it back into video range blindly.
I think Hubsan is somewhat more expensive for a reason. I got this RTF 107D for 69.00 on a flash sale, normally sold for 129~149 RTF. I am glad I did it.
Edit: oops, Mike I was typig while you made the post. I will try them and report bacfk.
