My RC2 controller defaults to Dual-band frequency and 40MHz bandwidth. Even if I change those, every time I restart the Neo it defaults back to those settings. With those settings it pretty much uses 5.8 GHz and only has 3 bands to frequency hope on.
I was at a club field during a drone race practice session. We discovered my rig was interfering with the drone pilots FPV. Every time I powered on I immediately changed to 2.4 GHz and 10 MHz bandwidth. This allowed enough unused channels for my rig to jump on an open frequency. However, I could not fly very far away without video pauses.
My guess is two Neos would work out this issue. However, other brands and a DJI might be a problem.
