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 -.
