Use the Settings from Transmitter!!!
If you are pairing the app with the Transmitter it will ask you sync from transmitter or to transmitter. I picked the wrong one. And my servo died. Use : !!!! Data from Transmitter !!! I thought there was an update and I wanted to sync the update to the Transmitter but all the settings the app gives my were wrong and at the end my servo died 20 minutes later. Very dangeres. Shame on you Spektrum that you are not thinking about a hilbilly user like I’m.
