Do you have a sdcard installed?

Yes I did and took it out. All seem to work now. Thanks alot, I have to do a test flight when the rain stops. Will post the resuls.

Thank you very much.

My initial test had couple clitches, to fix them had to remap the servos and reversed pitch channel.

Tested with Altitude Hold and Loiter. Lift off to 10 meters and tested basic functions. Seems to be stable.

Is it possible to connect telemetry module to this FC 405 v4. Can not seem to find free port. Thanks

Same number of UARTS as v3 - Speedy Bee F4 V3 — Copter documentation

I have used ArduPilot firmware : /Tools/MAVESP8266/2021-10-15 version 1.2 of the MAVESP8266, flashed an ESP8266 Wemos Mini and attached it to serial port 3. I have the same setup on my other drone which has Mateksys H743. and in that case attached to serial port 2. Same protocol and same bvaud rate. I can use UDP to connect to my Mission planner on Matek but not on my F405 V4 only difference is the port number. Following is My Matek setup on serial port 2

Hi any suggestion to my telemetry problem, can not get it to work. Thanks
