Tello 1st flight test after 2nd RYZE repair, movie prepa.

I got 2nd alternate Tello.
I tried Test Flight and cofirmed the followings.

1. Available to control Tello safely without alarms showing WIFI comunication within 80m * hight 30m.
2. Until just before landing, this Tello does have communication.
3. At landind, communication was lost and it showed red LED.
4. I do not know why Tello communication lost within 2m from me.

RYZE requested me evaluate their repair.

My answer is 

1. Repair this time should not be!  If RYZE did not send me a default Tello as repair.
2. I want RYZE to deliver right Tellos to clients after repair.

Now preparing a movie how Tello flies correctly if it is right.

Wait just moment please.
