Pinout for A02 VTX
Noticed: When you solder the VTX, pls follow the diagram for A02 VTX, in which the second port under ANT(MMCX) is GND, and it corresponds to the black wire of the 6-Pin FC Cable. If you have received the VTX with a diagram of "SW" or just black in the GND place, Please don't worry, it's just the typographical error, we have corrected it in the next batch.
How to Connect with FC
Here is an example of how to connect the A02 to a flight controller.
How to Use the Pit Mode & Change the Frequency and Power
PitMode allows racers to power up their video transmitters during race events without interfering with other racers, and it still has the ability to change VTX settings or do some testing. The range is limited to 2-3m and transmission happens on the selected frequency.
The PitMode is active when theRed/Green/Blue Power LED flash.
How to active and exit the PitMode
Press the Button on the VTX twice to active Pitmode, double-press again to return to the previous power state.
How to Change Frequency & Channel & Power
Enter the OSD menu by radio transmitter sticks ( Pitch Stick UP and Yaw Stick Left). Then FEATURES -> VTX SA to change the frequency and power.
Switchable power includes 25mW, 200mW, 500mW and 800mW, and the PitMode is supported on this VTX.

Right away, this is the best 65mm Whoop I know. Not even close.
I ordered two, one is more or less stock, just the PEEK motor screws and V3 cockroach. The second is upgraded to 0702 27000kV but will go back because I like the 25000kV more because of smoother throttle response and perfect betaflight tune.
Now the but:
1. On both quads I had to replace the BeeEye for a spare one because both are out of focus.
2. the yellow props were way too loose and very brittle. I lost two on my maiden. Black, blue and red are very tight (too tight for such a fragile prop) but if you get them on without bending them, they will last.
3. why does the quad not come with the lighter frame right away?
4. PH2.0…. You know the drill.
On that price point, even after the frame and PEEK upgrade I can forgive these quality issues. Especially considering the great tune and quality FC and motors. But be sure to order a replacement cam and props right away.
This was kind of a late night lark. I'd seen this upgrade for the Mk3 for a while and pondered whether it was a gimmick or not, and I'm pleased to say it's a genuinely good upgrade. It has reduced the noise of my Mk3 considerably. I haven't noted any significant increase in print quality, but the old drone of the bed is gone and that's completely worth it.
