I have been working on my quad for about two months now. It utilizes a MPU6050 accelerometer and gyro, hobby king ECS , motors, and frame. I am using a 3cell lipoly batter with a China RC controller (4 channel). I have recently moved the acell/gyro chip onto a peice of soft wood ontop of some harder rubber to cut down on vibrations. I am using an arduino uno with custom code to control the quadcopter. My code is simple right now and gets the input from the MPu6050 chip and uses the arduino PID library, and then adds the new output/offset to the throttle coming in from the RC controller and sends it straight to the motors. I am using interrupts which make it a lot faster that PulseIn as I was hoping for more responsiveness. I think my issue is vibration of the accel/gyro or the gyro is updating too slowly...? Here is a video of me trying to tune it. I increased and decreased the PID by 0.01 and it either doesn't have enough or goes insane...
I'm sure you guys have seen this before and can help me out!
