Thanks for your reply, I can understand the power system you are using now it make sense to me. I thought of taking the same approach where the brains and muscle have 2 saparate power source too.
HAHAHAHAHA funny one on the payload question. i was actually thinking of using a smaller Brushless motor. so need to know to the trust from a smaller motor will be sufficient for stable flight
I have 2 more question i hope you don't mind helping me with.
1. Notice you have Phidgets Voltage sensor on your quadcopter. How does it apply to the quad copter? or what is the reason to use the voltage sensor?
2. I also notice that your ESC does not get it's power source from the 1061 board. I notice most ESC will need to get the power source from the red/black/white wire but yours the red wire was removed. Is this a special ESC or you redirecting the power source to the battery?
Thanks for your time, And i love your quad copter good engineering.
