Springs are an easy part to get made ,we had a set of airbrake retension
springs made for our Kestrel years ago.Just find a local springmaker and
take the old set with you and describe the type of use/action they do.
You will probably not even be able to tell the difference between a Grob
part
and local product.
Your aircraft engineer will be able give you a name of a company he/she
uses.

Anyone know where I can get hold of a set of rudder peddle springs for and
Astir CS.

Apparently the a/c manufacturer doesn't have any..
...very strange!...

Thanks
