Hello and good day Racerman17. I am sorry to read and to know the issues that you are having with your DJI Phantom 3 Professional. Since there are stress cracks on the said drone the best thing you need to do is to contact DJI Support at https://www.dji.com/support?site=brandsite&from=nav for us to be able to check the drone and for us to assist help you with this issue. It is not recommended to fly the said drone if these are stress crack on it. This cracks might affect the performance of the said drone while on flight and may lead to an unwanted incident. Thank you.

t is convenient to adjust certain parameters to the way of driving each one, for example stress crashes can be caused by an abrupt adjustment of the brake parameter
