Hi I'm having trouble setting up my S900 Hexacopter
I have programmed my replacement Futaba T8FG transmitter in the A2 software.
then when I prepare for flight and I get a flashing blue led.
I try and enter the calibration mode and the led does the correct sequence but goes straight back to flashing blue LED.
I can't power up or anything.
I can successfully complete a motor test in the software no problem,

Please let me know if you can help me with this.

It sounds like your end points in the A2....you should have a 3 way switch mapped for manual, atti and gps. Go to that tab in your A2 Assistant and see where the arrow is pointing when you change the switch. Also go in and change that “manual” to atti. So that will give you atti, atti and gps. Let us know if that was your problem. One of the problems is if you have your switch end points off it would also flash blue if it’s on the RTH side. Let us know how it goes.
