So I updated my firmware which took 20 minutes or so and now I cannot take off.  What gives?  the only indication is the app tells me no signal, now i've done some searching and found "re-link" the controller but i am uncertain of how exactly I go about this.  is that the same as the initial setup where i hold the power button for 2sec after hitting it once?

help please!!!

Got it re-linked.  I didn't have to do out of the box so i didn't know the procedure.  Quick google search did it!!!

Glad to hear that you've solved it. If you meet any issue, feel free to post it here.
