So for me, it's tx on, warning flashes for proper channel after it checks for someone else on the channel. Then I get a warning of no arm until stick is in the off position. Install packs. Install Deans. Flip rx switch on. Return throttle to off.
Turn switch on tx to kill throttle off lock. Surface/range check. Now ready to crash......err fly.
Are you powering the esc BEFORE you power up the rx?
I set my bigger birds up almost like you do but when I first plug in the packs, the esc is still UNpowered because of the shunt.
However the rx IS powered up. Sometimes I also use a seperate rx switch - especially on the really big birds with failsafe switches etc.
My point is, the rx gets power while the esc is still unpowered.
That way I can check control opperation and throws, range chack etc with no fear of the motor starting.
I then get the model out to the flight line ready to taxi. Only then do I plug in the main shunt and power up the esc.
The main power shunt is last to get plugged in on take off and first to get unplugged when landing.
I use APP's as my shunts.
