"I am inclined towards the most appealing option i.e. #3.
I am also working on the same thing. Have my quad up n flying but now i need it to do autonomous stuff.
Reason i belv #3 is most appealing is that, the inner loop of stabilization and quad…"

Geetesh Dubey commented on Chris Anderson's blog post Another Sparkfun autopilot--this one with a full IMU!
"A thermopile can never give u a reliable tilt or angle readings for pitch or roll as the temp differences between the sky and earth changes , where the thermopile only looks for the absolute difference and the controller tries to minimize that…"
