Exactly, XT30 connector are much heavier, but they give so much less battery sag that compensate for the weight. You must remember that new PH plug might work fine, but after few cycles of connecting the battery they tend to get hot during flying (which indicate some resistance and voltage drop). XT30 you may use few thousand times without any degradation in performance. Thanks for your kind opinion.
Yes. But not for range but for smaller latency. Flying in small spaces require fast response which is much better with crossfire. And also I must say that indoor there are much more 2.4GHz noise from wifi which also makes frsky less ideal.
I set my crossfire to 150hz mode with telemetry. Rssi on eight channel showed on osd on upper left corner. I have been flying with a sound ringing when crossfire sets itself to 50hz mode and still then felt like it was faster than frsky.
I use only 3 wires for connecting crossfire nano to crazybee flight controller: 5v, ground and Ch 1 out set to crsf protocol. Crsf wire is connected to rx1 on the flight controller (so I can't use smart audio for the camera). You may use one of the other 3 remaining pins on nano receiver to connect it directly to the camera to use smart audio directly from the transmitter although I never tried this solution. I just don't use smart audio. I don't use two way connection for crsf because I don't need any telemetry on the transmitter. Betaflight Osd is enough for me.

Nice flying!
Thank you.
Great video and flying. How are you not having a lot of battery sag? Is it the xt30 connectors?

so uh.. did you place the label vertical on to/bottom of the video or is it besides the video? meaning: can you confirm what feed is what?
Left is 22000kv right is 19000kv
nice flving and comparision, but do you really need crossfire for indoor :)
Yes. But not for range but for smaller latency. Flying in small spaces require fast response which is much better with crossfire. And also I must say that indoor there are much more 2.4GHz noise from wifi which also makes frsky less ideal.
crossfire without telemetry?
I set my crossfire to 150hz mode with telemetry. Rssi on eight channel showed on osd on upper left corner. I have been flying with a sound ringing when crossfire sets itself to 50hz mode and still then felt like it was faster than frsky.
Tomasz Łęgowski could you share your wiring? CRSF on Rx3 and Tx3? What about SmartAudio?
I use only 3 wires for connecting crossfire nano to crazybee flight controller: 5v, ground and Ch 1 out set to crsf protocol. Crsf wire is connected to rx1 on the flight controller (so I can't use smart audio for the camera).
