At 25mb, the second user's channel is deactivated to prevent crossover.

If the first user uses 50bm, the 50mb user's goggles will shut down without warning if the second user invades the 25mb bandwidth.

As a result of repeated tests it keeps happening. This is a fatal flaw.

A warning of bandwidth violation must be raised and the channel must be disabled.

My drone disappeared with this error.

Always use a channel as far away as possible from the other DjI FPV drone. Like ch. 1 and 8 for 25mbps or ch 1 and 3 for 50 mbps.
