It’s been a long time since I’ve had to deal with R/C and a lot has changed in radios. I bought a pixhawk kit with a PPM encoder and a radio with the flysky fs-x8b reciever. What I’m struggling with, is connecting the flysky reciever to pixhawk…
From what I found, ppm encoders are usually connected to reciever units, but the fs-x8b supposedly has a ppm encoder built-in. That means I can connect the fs-x8b directly to the pixhawk? If so, that just leaves the question of wiring, which I’m also confused on. The fs-x8b has 4 pins: PPW, SBUS, VCC GND. From my understanding, I need a harness that connects SBUS, VCC, GND into the standard SBUS 3pin rc connector on the pixhawk?
My understanding may be incorrect, but if you want to use PPM instead of sBus/iBus, you’re going to need to connect to the PPM/VCC/GND pins and leave the SBUS pin out of the equation.
I run my Pixracer with an ia6c with iBus, so I use the SBUS/VCC/GND pins and leave out the PPM pin.
Interesting. So looks like I don’t need the ppm encoder from the kit I bought, but I’m missing a 3 pin wire that would connect the fs-x8b to pixhawk sbus. Looks like I’ll have to make one myself, but that’s easy stuff.
I used a kit of DuPont female to female wires, and just super-glued together the three that went into the Pixracer (ends up being pretty much exactly the footprint of a Futaba servo plug), and kept separate the leads that went into the ia-x6c.
