Luminier QAV 250 - Need Help

[xpapaxsmurfx]

Got a QAV 250 (RTF) a while back, but I still can't get it in the air. Here are the specs:

• Motors: 4x Lumenier RX2206-11 2350Kv motors
• ESCs: 4x Lumenier F390 30A BLHeli ESC OPTO (2-4s)
• FC: F4 Advanced Flight Controller
• Lipo: Lumenier 1300mAh 3s
• Radio: FrSky 2.4 GHz ACCST Taranis X9D Plus
• RC TX: FrSky DJT
• RC RX: FrSky D8R-ii Plus89
• (I also have an FrSky X8R)
• FPV Camera: 700TVL CMOS Camera
• Video Transmitter: Fat Shark Cased 5G8 TX
• Video Goggles: Fat Shark Teleporter v5

It was tested to fly SBUS, but my RX isn't set up for that (?). I resoldered the FC so that it can fly PPM. I also set my radio to fly PPM CH 1-8 through the DJT External RF. I don't even know what I don't know. Did I mess up by trying to fly PPM?

Should be able to use sbus or ibus. How many signal wires are going from the receiver to the fc?
There should be 4 for ppm
