I used to manually control the hexacopter through controller TURNIGY TGYi6 and the flights were fine. Yesterday, the copter hit the wall by accident and crashed from 5 feet high. I tried to rearm the motors and everything seems ok.
Today, when I tried to rearm and it fails. The TX RX connection is well connected on the controller and I placed left stick to right bottom position for long and still get un-armed.
I also tried ESC calibration and it perfectly work. However, when I come back to normal mode, and failed to arm anyway.
Could anyone help me with some solutions? Thanks.
