problems with your quad!? maybe a simple calibration will do the trick,
galaxy visitor 2 calibration link: http://youtu.be/CNZY-10lDvs
see if this vid can help...
common quadcopter problem vid was created because i had two
quads (hubsan x4 and WL toys v959) that had a calibration problem and i didn't know why the heli didn't stay stable, and all i needed to do is a simple calibration to fix the problem.
what happened is i thru my quads in the trash.
so i hope i will help not doing the same mistake i did.
