Hello,

I'm using the Spirit GT in combination with a Radiomaster rp3-h. When powering up the helicopter, half of the times my sticks and switches do nothing. After powering up i get all the right beeps. Swash is moving up en down and then nothing works. I have to unplug the lipo to try again. It's totaly random if it works or not. Sometimes is have to unplug and replug 4 times in a row. Very frustrating. I have tryed unplugging and repluging the rp4-h with the spirit gt already powered up and that way it always works well. TX is a Ranger micro in a tx16s. Tx, rx and spirit unit are all up to date with the firmware.
Can you please help me out?

Hello,

could you please share your wiring?

We have identical setup here with no issues, so we can check also settings. Do you use a bufferpack?

CRSF has seperate rx/tx pins, so for your telemetry problems it sounds like one of the two is not connected right. Not sure if this also causes your other issue.

P. S. @ZeXx86 the wiring page of the manual is missing the CRSF receiver example, I could only find it on this seperate page.

I do not use a buffer pack. On the rp3-h i have the output marked tx connected to the Rud S. Rx is connected to Ele/pit/ail S.
The + and - output is connected to the Rud + and -.

It sounds like there may be some issue running CRSF / Radiomaster RP3-H (CRSF more likely than RP3-H) with Spirit. I would strongly advise you do not run this setup. Our setups appear to be very similar and I have had two crashes due to an electronics malfunction with the exact setup you've mentioned here. These weren't spoolup tip overs or anything, these were extremely hard into the ground at high head speed crashes.

Please let me know if you have any resolve or if you have any more information. In the meantime I'll be switching setups. Good luck.
