I am operating with pixhawk 2.4.8 and mission planner. Firmware is uploaded and all alignments up to the servos are apparently successfully completed.
I get to the step which says disconnect USB and battery, then reconnect battery. The pixhawk goes thru its whistles and bells and ends up as follows:
FMU and IO LEDs are on and steady green. The ACT LED is constantly blinking blue, which I believe is normal. The large central light is green and blinking, which I believe means that the unit is ready to go, but does not have a GPS lock.
When I press the arming switch it goes from blinking to steady; the central green light continues to blink green; there seems to be some sound from the esc's (not positive of this) and one of the motors gives a small twitch. I have cut the red (power) lines from the esc's, the ground and signal wires are connected to the main out ports 1 thru 4. The brown (ground) wires to the esc's are in the top pin position
Transmitter has no effect in any axis and motors do not respond. Please HELP!!
