After successfully bringing 4 quads back to the future with your help I'm asking again It is the last one, a Code Red designed 3" racer using 1000 mAh 4s packs.
I will be replacing the FrSky XSR Rx with a Radiomaster ELRS-RP3-V2 RX (the twin antenna version) and maybe the VTX.
The FC is a Lumenier Micro LUX F4 V2 which I just reflashed to BTFL 4.4.3 LUXF4OSD so that is great.
ESC is a Lumenier 25Ax4 OPTO 2-4s BLHeli_S
VTX is a Lumenier TX5G2R 200mW ((changed to TBS Unify Pro 5G8 V3))
1. Replacing the The ELRS Rx looks easy, connect to GND/+5V/TX3/RX3 (or TX6/RX6 ?) on the FC.
2. But I am really confused about the VTX arrangement on this quad. Note: I read that this FC did not have a good OSD. Maybe that is why in this old quad we have battery power coming from the FC to a 12V Pololu which powers the VTX and camera (Foxeer Arrow V3) with a blue (VSEN) wire going to the camera, which is messy because the VTX could have run on 4s power, its operating voltage is 7-20V, and the FC has 5V out, so no need for Pololu? Anyway this is where I think a component change might be in order. But I have never built a ELRS Rx version all my others have Crossfire. So I don't know which VTX would work with this FC and camera to give me SmartAudio with all of the OSD choices like RSSI, LQ, batt total and cell, flight time, modes, etc. It looks like this VTX (camera) only gets voltage to display, nothing else. If I get a VTX with a SmartAudio wire can I simply connect it to either TX3 or TX6 (whichever one I don't use for the Rx) and get SmartAudio? Any recommendation then?
Oh yeah, this FC has buzzer pads, which I used for a remote buzzer. Can I use motor beeper instead with this ESC? It was running DSHOT600.
