Problems with Bepop 2 with arducopter

Hello,

I’d like to know what you think. I recently bought a Parrot Bepop 2 with the intention of upgrading it to an Arducopter. Using Mission Planner to flash the proposed Arducopter firmware I succeeded, except that currently, despite a gps and accelerometer calibration, when I take off the drone turns on itself and ends up crashing. Do you know what parameters can affect this behaviour?

Thanks for your help
