PPM Encoder not working as intended

Hi everyone, It’s my first build for a quad. The specs are:
A2212 13T 1000KV Motors
Simonk 30A ESC
Pixhawk 2.4.8
Lemon 3S 5500mAh 45C 11.1V Battery
F450 Frame
PPM Encoder
1045 propellers
FS-CT6B Transmitter
FS-R6B Receiver
I am facing an issue where the PPM encoder is not working correctly. Although, the receiver is lighting up, when the transmitter is turned on, only the roll and pitch controls are working. Other than that, no control is working as intended. Please help…



Am having same problem

Same here. I bought 8 of these units and none of them work!! Can anyone explain why? I bought one of these about 2 years ago and it works. But the batch I bought in the last 6 months do not work.

Looking for help.

Joe
