Second hand or lower spec Gyros?

[Tom Sawyer]

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?)

I have purchased and sold many used components and only got one bad speed controller. The GY401'a set the standard for gyros a few years ago. There are better ones out now that are around the same price though.

I am a strong proponent of buying quality electronics. You can find used Spartan Quarks for a very reasonable price. I've even seen new ones on sale here and there for under $100.

Thanks, maybe I was a little over cautious and missed a bargain. My father lives in the states so maybe I have another option by buying at US prices and getting it shipped as a gift.
