I have my spirit pro hooked up to a 4949t receiver and every time I disconnect power to the FBL and reapply power the receiver starts flashing again , but here’s the funny thing if I unplug the receiver cable from the FBL which is in the RUD port and plug it back in , the receiver goes sold indicating it’s bound . It happens every time I disconnect power supply from FBL . I have tried the same receiver in a different heli and it works fine . Any ideas as to why it would go into flashing mode when powered up and when the power to receiver is only disconnected and connected back up it Works as it should .

Are you using Jeti integration cable?

This receiver shouldnt be just in RUD port, this is used only for powering.

The 4649t is hooked up like my other 4 Helis and as per manual . power From RUD and signal from (Ail )port on right side of FBL if pins are at the back
