It is unlikely that that throwing more volts at the problem will solve it.
I thought of that actually. However, I am observing it's behavior while varying pids, it is taking bit efforts to lift off. like it wants to lift off but something is dragging it down. My best guess is LiPo 3s 2200mAh battery is quite heavy. But as I read online, config is ok. F450 frame, A2212 13T 1000KV motors, 30A escs, 10x45 props. Coz it only has battery that heavy others are only arduino, mpu6050, receiver and wiring that's all.
Btw do you guys this configuration is ok or i need upgrade something in it.
Following is the observation:
p_roll I_roll D_roll P_yaw i_yaw d_yaw signs result
2.1 0.04 0.3 3.5 0.02 0 "q+ + -

1.5 0.04 1.5 3.5 0.02 0 "q- + -

q+ + +" bad rolling and pitch
1.3 0.04 18 4 0.02 0 "q- + -
q+ + +
q- + -
q+ + +" good throttle up to 60%
ignore "q", signs are these "esc_1 = throttle + pid_output_pitch + pid_output_roll - pid_output_yaw;".
I don't know where I am wrong but circuit seems ok, coz receiver signal checks out, gyro checks out, motors spinning in right directions.
