I stripped down an S800 Spreading wings. I installed a Pixhawk along with a 3DR ublox Gps. It actually went together smoothly. I then bought a Attopilot 90a board to make a power module upgrade for the 6s batteries. Everything checks out fine on power up.
I selected the proper firmware for the hexacopter and confirmed that the motors where spinning in the correct directions as per the configuration chart in as found in the APM Copter online instructions.
I calibrated the ESC's as per instructions. That checked out fine.
All systems green, full GPS.
selected loiter mode
raise throttle and the hexacopter does a back flip
second attempt the same.
This is my first 3DR build and any advice or suggestions would be great. I know someone has put a pixhawk on a S800. It's got to work. I'm clearly doing something wrong or missing step. I'm going in circle now and could you a little light on the topic.
Thank you in advance
