Thank-you all for your replies. The normal hookup wire found at most electronic suppliers is not the real flexible stuff found on R/C recievers. It stresses too much when it is out in the breeze behind an airplane and breaks. Is the 19 strand the flexible wire I am looking for? I searched the Cermak site but did not see the replacement antenna wire. Also, I am an electronic technician, so doing repairs like this is no problem, I just can't find the wire I'm looking for.
