Thanks for the info about using just the controller as I never thought about that. I just flew again using my 10 inch Ipad from work and had no problems. Then I used my Note 9 phone with version 1.1.5.3 and it worked fine also. I used both for several minutes trying to duplicate the freezing issues when using the IPAD mini 4 . I am wondering if there is just some compatibility issue with the Mini4 and the
EVO 2 as I use it all the time with the EVO 1 and Mavic 2.
I was also able to use the 10 inch IPAD today as my Liftthor finally arrived yesterday. They upgraded it from the first model which I use on the EVO 1 and I think the design is a lot better and sturdier.
