hope you get your Tello soon very fun and easy to fly:giggle: I purchased Nimbus Steel Series game controller from Best Buy to use with iphone and it works perfectly I'm having lots of fun with it
just sign in to DJI Store products scroll down to Ryze Tello slide to the right and you will see Tello and all accessories press on veiw all and then press on whatever you are interested in and it will bring up the page
when you try to purchase if it's not in stock there will be a box that says in stock reminder
put in your email address and it will confirm you are signed in
I don't think the charging hub exists yet I've only seen picture on the back of the box. It would be cool if it was designed like the one for the Spark Power Pack
