Regarding this cable...

http://store.spirit-system.com/en/acces ... cable.html

... is it easy to make one myself, or is there something special involved?

The reason I ask is (a) I need roughly 25cm length on my heli, not just 15cm, and (b) I'd prefer not wait for one to arrive.

Also: are all three pins needed? Can I just connect the signal and use the other two pins for the ESC fan?

Thanks

Maybe Tomáš will answer and explain, but please remember that we get ALL THIS for free in firmware, and the only way that Spirit can recover some of the R&D and Dev costs is by selling those cable accessories...

Check the prices Coco. I think €6 is just to cover their costs; the real money is made on the flybarless units.

Of course, but still, nobody forces them to release so many nice updates all the time ))))

Oh, there's already a thread on this. I searched for "telemetry" but someone used the German spelling in the other thread, so search didn't work.

The brown/black is already connected via the BEC, right? So I only need the yellow signal wire, and it's just a straight connection (no resistors or anything else)?

Yes, only orange and brown wires are used. Red must be disconnected always.
The connection is direct with no resistor.

Since connecting the HobbyWing v4 (120A model), I can no longer get the Graupner HoTT integration to work. Any ideas? It might actually be switching ESC telemetry on in the Spirit settings?

I have 2 wires (ground/black and signal) connected to the receiver, and 1 wire (signal/orange) connected to the ESC.

Edit: after switching "ESC telemetry" off (disabled), the Graupner integration is working again. (ESC telemetry wire not connected.)
