Will the secondary controller (student controller) work as a primary and have full functionality. I have 2 controllers and 4 batteries so after a couple of flights if my controller battery is low my intentions would be to just shut off one controller and turn on the other to use. Would that work ok? Thanks in advance.
You could fly for a while with the one controller, shut it down, let it charge, fly with other controller, etc. as long as you have a v1 controller with a EVOII v1 aircraft. You can also have different livedecks work with different EVOII v1 aircraft, like the controllers, simply have to rebind them to different aircraft.
Note the relationships are:
v1 controller to EVOII v1 aircraft
multiple controllers paired to one aircraft active (e.g. many to one)
one active primary controller, other controller secondary
multiple livedeck paird to one active aircraft (e.g. many to one)
however keep in mind only one active aircraft with multiple controller (one primary) and livedeck (e.g. one to many)
For example, I can use the controller from my E2P with regular EVOII and vice versa by rebinding. Or, I can use EVOII controller as 2nd paired controller with E2P having two controllers (one primary, one secondary). I can put both livedecks on one aircraft by rebinding them to active aircraft, or, put one livedeck active one each aircraft. Note the relationships above, e.g. you can not control multiple active aircraft at same time from one controller, single livedeck can only access/view one active aircraft at a time.
Oh, btw, fwiw, keep in mind that when it comes time to do a fw update, you will need to unbind any of the above secondary bindings (e.g. 2nd controller, livedecks etc) or fw updates wont work.
