There’s absolutely no info on the product page or their FB group about VTX table. The Tank Race II is new so it hasn’t made its way to Betaflight preset yet, so I had to make my own VTX table for Betaflight. You need to enter this in the CLI to get SmartAudio (VTX control) working.

Output Power Testing
Tested the Rush Tank Race V2 VTX using the ImmersionRC power meter V2.
What seemed to be a bug with this VTX, is that when I set the output power to MAX, and channel to R7, the VTX started to act weird. The video signal intermittently turned off and on, while the output power switched between 540mW and 650mW. Also I couldn’t change any VTX setting as it always reverted back to MAX power and R7. I also tried changing VTX settings using the push button on the VTX but it was the same, settings just wouldn’t save.
In the end I had to connect the FC to Betaflight, and change the VTX settings in the Video Transmitter tab, I was able to get out of R7 on MAX power. I didn’t have this issue on R1 on MAX power, the issue only happened when it was on R7 on MAX power. It could be a faulty unit, but you should check if yours has the same issue before using it on a drone as it would make it impossible to fly.
