Flown this a couple of times and so far it feels good. I'm unsure if one of the motors does not look as healthy as the other 3 but that is the only thing I have seen. Footage of my flight is here https://youtu.be/MNNiWmoH3kI
The quad is good for the price. Well assembled, well cabled, very nice. What’s wrong in my opinion: - the R9MM receiver was flashed with an old release of FLEX firmware. So I had to solder wires to update firmware. - the R9M modules was not previously binded with receiver, and it not had FLEX firmware, so I must had to flash it with FLEX firmware too - the FPORT inverted signal from receiver was connected to SBUS input, instead it should be connected with uart TX. So no way to get telemetry back from FPORT. I had to solder the the inverted FPORT to UART TX, and set BF with: set serialrx_halfduplex = ON - the audio signal from runcam split 2s was not connected, so not audio, even if the camera was capable to.
