There are know compatibility issues with Spektrum telemetry receivers and flight controller other than those made by Spectrum/Horizon/Eflite. I’ve flown Spectrum exclusively for years, and this is the only idiosyncrasy I know of with them. Hope this helps you.
“Known” compatibility issues, that is.
Thanks for the input. I have a frsky taranis transmitter and I might try that along with a frsky receiver and see how that works. I’ll post the results if I do. My V-Tail project has been on hold because I started another project with the Hquad 500 drone. Just waiting for winter to be over.
