I am interested in making an MAV below 25 grams.
Attached picture file shows some modules which I am using.
My MAV consists of BLDC motor, ESC, IMU & barometer, Arduino pro mini, servo, and battery (1cell 140mAh). As you can see, one lithium-polymer battery supplies power to every part.
With these modules, the performance which I want is only achieved during 10 seconds because of low battery.
What I want is to decrease the weight of my platform. I think that BLDC(2g), ESC(0.37g), and servo(1.2g) are very light. I consider replacing Arduino-pro mini and IMU & Barometer to other flight control (FC) board.
Would you recommend a small and light FC board?
I ask you for advice to solve my problem.
