When I bought my Mavic Pro it came with RE goggles and a Huawei MediaPad T3, it had very little use and the person I bought it from swore by this.
I have never used it as I have a iPad Pro so can’t really comment.
Argos and Amazon are selling these for under £70.HTH. https://www.argos.co.uk/product/7193673
I used iPad 2 mini but could not view on bright days, bought a nexus 7 2013 from fleabay for £30 and hardly ever needed the cumbersome hood did not drop signal and easily hackable to run nice apps plus 2gb ram which is great.
This is curious. I was trying to get my Nexus 7 2013 working with the DJO Fly app but it was having none of it. Turns out you have to be using a 64bit ARM processor for the Fly app or it just isn’t going to work.
t3 works perfectly for me. I don’t have a newer drone so use the older version of dji go. I just installed the latest version and it works fine, obviously I cannot test it due to not having a current drone.
