 ## E016HV2 - *80*
 Models: E016H v2
 
-**Only 1 ID available** so you can't fly multiple E016H v2 at the same time.

 Option for this protocol corresponds to fine frequency tuning. This value is different for each Module and **must** be accurate otherwise the link will not be stable or bind won't even work.
 Check the [Frequency Tuning page](/docs/Frequency_Tuning.md) to determine it.
-

+**Again make sure to set the RF frequency right to be able to bind**. FYI, on my module I needed +80.
