Thanks.
I'm a cheapskate because I don't like to support western marketing brands for doing nothing (Its all made in china anyway), so I can just aswell buy it from somebody chinese directly.
So I bought the GY 520, just because its PID, its MEMS, and its so cheap I got nothing to loose.
Are you flying any aerobatics with this gyro?
You will enjoy the Gy 520, it is a step up from the HK401.
I had one on a HK 450 Pro TT Heli and it worked nice.. eventually you will out grow it though.. and then i can strongly recommend the Quark, which I am using now..
Hopefully thesevids will show you the difference..

And this is the 450 Pro TT again with but now it has the Quark and some additional swash tweaking.. Its my best 450 Heli now and the Quark plays a big part in that..
