I’m currently building my first heli. I’ve now reached the wiring/connection of the electronics. I’m using the Hobbywing Platinum 150 V5.1 ESC, the Spirit GT1 as the FBL, and the Radiomaster RP3-H (ELRS) receiver, which I want to connect to my Radiomaster TX16S. Telemetry should be enabled as well.
Now my question:
Can someone explain to me in detail which cable needs to be connected to which port? The ESC has two cables with three-pin connectors. What am I supposed to do with them?
I have connected the receiver according to the manual. What do I have to do with the other cables (one yellow plug and one red/black plug)? Where exactly do I have to plug them into the FBL?
Wiring Help Needed
In my Spekrum setup on a omp m4 max I have ESC rpm wire (the extra 4th wire that is part of the set of wires from the omp esc) goes to the pin 2 (centre) of the ELE\PIT\AIL socket, and the other three wires in the normal order go into the Aux1 socket with signal wire to the top.SWorker wrote:I’m currently building my first heli.

The receiver (RX) is simple for me because I only have 3 wires; power and negative go to the Rud socket (note:- the bottom pin if the Rud socket is neg and the middle pin is pos, top pin not used) with the signal wire of the RX going to the top pin of the ELE\PIT\AIL socket.
You need to know RX or TX wire from the RP3-H equals the signal wire.
Assuming yellow/red/black is from the ESC: yellow is RPM, goes in the middle of ELE/PIT/AIL port (you need to move the wire to the middle of connector for example by lifting the plastic tab with a needle, the other receiver wire can go in there too to make it into a single plug) . See governor page of the Spirit manual. If you won't use the governor it's not necessary to connect.
Red/black is your secondary BEC line, it can go for example in AUX2 or CH0. Do not connect power to the outside ports (ELE/PIT/AIL, SYS, SAT) in any case.
For telemetry see the hobbywing telemetry page of the manual. You need to connect the programming port of the ESC to SAT1, either by buying pre-made cable described in the manual or making it yourself, making sure to connect ONLY signal and ground to the correct pins on the SAT1 port.
