If you try to lift off slowly if may flip.
You have to lift off quick.
Slowly raising the throttle will do this
Note I have scrapped this frame due to vibration issues.
I can have a look at you hj file too.
Please post a picture of your system and a video.
This will help a lot with troubleshooting.
