Does the Femi X8 SE 2020 come in two versions, FCC and CE. The claimed 8 km range would be highly unlikely if sold in Europe in CE format.
Is not being able to fly at 8km a deal breaker?
The claimed 8k range of all drone manufacturers is only ever going to be theoretical / laboratory conditions anyway.
Bit like cars and their advertised MPG figure.
Meanwhile, back in the real world… 
But to answer your question @Overthehill
The fact they specify FCC there suggests there is indeed a CE mode.

8 kilometres is not a deal breaker but it would indicate good reception.
What sort of distance should I expect in CE?
Why does the Mavic Mini has 2.4 GHz AND 5.8 GHz but most other drones have only the latter. Is having both better?
@Markb1604 started a thread a couple of years ago which would be great to bump and expand on:
Tagging @Nidge and anyone else who could offer some input in that thread.
2.4Ghz is limited to 10mW for license free video transmission…
