blheli/plush 40A problem

hi guys, i have just installed my newly flashed blheli plush 40A esc, and every joint is soldered.
However, the rx signal doesn't seem to be getting through to all escs. When all linked together, i cannot calibrate all.... also there are sometimes 'part tones coming out from the esc. I.E. the 'tunes' are starting and the restarting...
I'm not sure what to do .


here is a video
