I wanna build my first micro quadrotors which can be used to design a multi-robot system to carry out a load cooperatively.
Each micro quadrotor should able to have a continuous flight time of 10 or 20 mins; the dimension of each micro quadrotor must be at most 10 by 10 cm.
Now my question are:
1- Is PX4 Pixhawk Lite is suitable as the autopilot? If not could you please suggest another autopilot?
2- What type of motors are more proper for a micro quadrotor? Coreless or Brushless? and Which manufacture?
3- Any suggestion on battery?
Thank you in advance.
