FrSky Taranis Q X7S ACCESS

<< < (2/4) > >>

Rogue1:
Also meant to ask, which "RF module" are you using with that Taranis QX7S TX ?  There appears to be 3 different 900 MHz RF modules made by FrSKY, and 5 diffenent 2.4 GHz RF Modules from FrSKY.

I bought a Taranis X9D plus 2019 about a year ago for my aircraft. It is possible to do just about any mix, etc. with it, assign switches and stick to ay channel, extensive telemetry - but I found I was using only a few percent of its capabilities. I only flew it once (eyesight is no longer good enough for flying models) but found the array of switches very confusing in the air.


I have been considering using it for some of my boats, as I have several receivers and various telemetry add ons, but haven't got around to it yet. I think that the complications would be less with a slower moving model, especially one you can simply stop in the middle of the pond and check the transmitter - aeroplanes don't do that!


Are the Neuron ESCs reversible? I think I still have a couple of them, the telemetry was very easy to set up, and the tx can show voltage, current, RPM (and altitude!) on the screen, or read them out. They are can also be saved to a log and transferred to a computer at home.

Evening JP and Dave


Sorry for late response...  JP, I've emailed over some details.  But for other readers, yes the extra 4 channels are gained by using the SBUS to PWM Decoder, I think these units can be daisy chained if required but I haven't tried that.

And you need one of these to configure it:

The RF module I use is the standard 2.4Ghz Internal, no special module.





In terms of channel usage:





One servo for the rudders on ch1, the two ESCs on ch2 and 3, plus two small servos for the ski push pulls on ch5 and 6, otherwise they're just on/off switches for lights, gyro, sound and water pump.


@Dave, I'm using the Neuron 40S ESCs, and using BL_Heli32 on my PC to program them.  Its there that forward / reverse can be set up and so much more.  Let me know if you want me to post more about the setup.


And yes, the built in telemetry is very cool indeed.  Voltage, current, rpm for port and starboard,  ESC temperatures, and ive added the GPS for speed over ground....


I'm really pleased with the options that the FrSky system offers when running a boat, you should try it for sure..!


Happy to post more if its of interest.


Best regards
David.

if you want to connect more than 4 extra servos to your sbus enabled receiver, i have found that these work quite well:

link to "that web site" for demonstration purposes only, i have no idea where else they are described.

DJW:
Interesting piece of kit. Are channels assigned by the software shown, or have you tried the FrSky channel changer..?
