The gyro only drift is a non-issue if you are used to flying around and flipping. The Ladybird V1 with accelerometer will snap back to level noticeably quicker when you put in a small angle and release the stick. The V1 will always eventually return to level, which is a typical multicopter response for a multicopter using an accelerometer.. The V2 when kept in a hover will require more corrections and if not corrected would eventually angle for the ground.
How bad is your V1 and how did it get broken?

I've busted my V1 mainboard, and and toying with replacing it with a V2.
