servo linkages

Does anyone know where to get some nice adjustable linkages? Preferably the turnbuckle style so I dont have to keep popping off my ends? Also need to be generic so I can cut to my exact needs.

thanks for any help

What kind of heli is it for and are you useing balls on your servo arms or the z-bends?Linkages vary with the size of the heli say a 30 nitro linkage will not fit a Trex servo so I really need more information than you have given.Please give more information and I will try to help you out.
