Fly sky steering spring replacement

[Exit13 230]

Well it didn’t take long to break the steering spring inside this GT3C mechanism.

The fix was relatively easy, I unfolded one spring link and re’hooked it. Now it’s a little shorter and a little more stiff. But I think I need to get my hands on some Replacement springs, can someone tell me where to sources them or what size I should try and buy?

 

here is a picture of the little culprit, any ideas where to get one?  Thanks again TC
