Spektrum SPM9747 Remote receivers
First of all thank you for your help. So for my updates: SPM 4651T receiver updated in v 2.40.0 . HW 130 HV V4 controller updated v PL 04.0.04 (the v PL 04.0.0.08 vbar does not work). brain 2 updated latest version. On the other hand if I remove the additional wire (P port programming to signal 5 brain) the telemetry does not work completely (like, temperature, voltage battery and surely others). On the other hand update SPM 4651T in v 2.37.0 , signal bar ok but not telemetry . I give up while waiting for further update. Thank you anyway.
