This is just a friendly suggestion.

If you ask for help people will be able to give you better responses if you provide the following:
Model of your Phantom & controller
Software Versions
iPhone or Android based
Mode of flight, Phantom or NAZA mode and position of switches
Battery State
Any other infomation relevent info or history, mods, recent crashes, recent updates, etc add-ons

The folks here are willing to help but they need info about your Phantom in order to give you the best help

Yep, I agree. There are a lot of good, experienced folks in this forum that are always eager to help others but a standard set of data is needed to allow them to properly troubleshoot online. In fact, if you can collect all that data, you might even be able to pin-point the main cause/s of the certain crashes  

People should also realize there is a search box at top right. If you have a problem with say yaw drift, type "yaw drift" in and you will probably find your question has been answered.
