yaw drift

Hi, I have a arducopter 2.5 with firmware 2.7.1

I was able to calibrate the PID for roll and pitch, work and the quadricopter type "+" is stable.

But in the air I can not stabilize yaw , rotates continuously.

I try calibrate the PIDyaw but never the res

pid setting problem with different throttle


I have a question, I try tuning PID with motor throttle at 20% , the tuning is perfect and stable, but when increse the motor throttle at 50/60 % the quadcopter starts to oscillate and becomes abrupt movements and nervous.

Then do the inverse, with

Quad+ Vs QuadX

Hi, what differences there is in quad+  and quadX apart from the mounting of the sensor in the frame.

who is more stable in flight, quad+ or quadx?

Is there are a difference in the dynamics in flight?

apm2 and MPU6050 DMP... question?

Hi, I have a doubt. The APM2 have a MPU6050 and this sensor have a DMP for fusion accelerometer gyro and external magnetometer.

My question is, Why in the source code not use the DMP of MPU6050 ? but use the traditional software DCM ? ... maybe is DMP
