just a beginner in drones ,just researched a bit and form a very basic PID code ,the problem is my drone is not properly taking -off very random directional take off,drifting in different directions each time i arm it and try taking off,its not perfectly vertical,where as my roll,pitch and yaw commands are all 0(set points ).can anybody help me in improving the arduino code
drone specifications
100 mmx120 mm x-frame
8700KV motors
2840 tri-blade props
original arduino nano FC
nrf24l0 receiver and transmitter
gy87 as imu
25A 4-1 esc
1000mha 70C 2S lipo
weight aprox.180gm
her I post snaps of my drone and two first trial videos,trouble is take off is random in every trials i try
.Its taking of bit not perfectly vertical,randomly drifting in every take off,can anybody help me in improving the algorithm for fine tuning?
drone specs. are

thanks Mark I thought about the battery issue once ,but when i researched over net i found most of the DIY drones are having top mounted batteries,so I opted,but now I think of modifying the frame to lift the motors so that centre of gravity and centre of lift become close enough.BUt Mark I am a newbee in arduino so pls help me how I can adjust the servo update rate to 100-400updates/sec.
