Difficulties to takeoff in offboard mode through mavros [closed]

I have an issue with the offboard mode on my drone.

I have a pixhawk as flight controller (firmware PX4) and I have installed a raspberry pi 3 as companion computer (Ubuntu Mate 16.04 and ROS Kinetic). Manually, the drone is flying very well. I can go to STABILIZED mode and fly correctly.

When I am using mavros on the rpi to command my drone over wifi and launched my program (rosrun package offb_node), the drone have difficulties to takeoff. It is trying then all motors spin less faster. After the drone landed. I don't think that it is due to the program because it is the offb_node example here ( ). All is ok with simulation on Gazebo.

The only solution can be a defective motor. Indeed, after the takeoff attempt, the motor 1 is spinning less faster than others. But it is weird because in manual mode, I don't need to compensate.

According to this situation, what do you think is causing that? I will buy another motor if I am sure that it is the problem, but the fact that I have good flying in manual make me hesitate.
