CONTROL SYSTEM OF QUADROTOR


For control system you will need to interface brushless controllers(ESC). so find some mixer that support such a high update rate (>200 steps/s). and see how it works.

also, find i way to interface with a rc-receiver,and the gyros, gyro sensitivity can vary from as low as 50 degrees/s to as high as 450 degrees/s we dont actually need very high sensitivity ,so no need to throw your money
once you have all that running, build a frame and buy the rest of the esc and motors. the actual stabilisation is (relatively) very easy.

i will be posting the interfacing diagram later

Planning to get Brushless motor


we are planning to get brushless motor to continue the project as brushed motors dont have required thrust,i.e. power to weight ratio is less ,
for any flying object power to weight raio must be in the range of 1.1 to 1.8
we are planning to get Emax cf2812 brushless motor.
