You only need to bind on first use with your th9x.blackmoon wrote:One more question,
The bind button works like other modules ?
i.e. push while powering on the transmitter ?
Because this can be a pita,
(It is the same with the wltoys V939, biding each time you change battery is really annoying, because you don't have much time to do it. I stoped using my V939 because of having to try the bind 5 times in a row before being fast enough to achieve it.)
If this the right behavior, why not implement the following (if feasible) :
Ditch the bind button and auto bind at power up like the rtf toys transmitters do it.
Maybe you did it the wrong way ?
Try this for proper binding:
Power on the Model (v939), then push and hold the bind button on your 9x while powering on.
Wait a few secs and watch the led on Model (v939) til it goes from blinking to solid.
Power off your Model first, then your 9X ! Really important !
After that, if you want to fly your v939, power your TX FIRST, second your Model !
Your binding should then working and no more every flight binding procedure ...
That's the way we get with such spektrum models/tx ... no matter how secure or insecure such proceder is or how we did it before 2.4 GHz.
On powering, FIRST TX then Model, after flight FIRST Model then TX, thats the rule
Like on other TX / RX combinations,
first power tx, second Model on you want to fly,
and after flight, first Model off, second TX, to prevent damage etc. .
Did you tried that ?
