If you only have a 7e you won't be able to use an external module, only the T8SG V2 plus can do that.
(The T8SG V2 plus is just a better 7e

)

Yes, a module with an actual LT8920, connected into the module bay of the T8SG V2 plus.

Because it doesn't have an external module bay, same reason you cannot use a R9 or Crossfire module with the 7e.

No, it doesn't work the same as internal modules.

Yes but not directly connected to the SPI bus in deviation (we don't want to support a 5th internal module).
External or nothing

But just wait anyway ... we might be able to make it work with cc2500, but as I've already said there's no guaranty.

If the lt8920 is necessary ,
I suggest you support a 5th internal module
so the players can choose by themselves. That would be great!
My 7E have 5 connect spot with B7 B12 A13 A14 A15,so ……please please!

Any news on the JJRC H31 protocol? I am also interested to see if this one is possible. I do have a T8SG v2 Plus with an open module bay, so I would not be opposed to that option. Just curious.
