Second hand or lower spec Gyros?
How robust are Gyros?
Im in the process of buying a T Rex clone and this might be one of my first upgrade items.
Presuming the better the servo the more it will help my flying I was looking at something like the GY401 but new it will cost not far off what my Heli will cost.
I have seen GY 401's on E-bay for a quarter of the list price (one sold yesterday for £43!) but there are no guarantees its not a fake /damaged etc.
Is it generally ok to buy second hand / used /pre owned and if not do I really need a GY 401 yet anyway?
(I have no interest in extreme 3D and would just prefer to eventually be able to achieve a predictabe flight so I guess its servo performance over features?)
