Finding control line items hard to get? Pilot Petes can help.
This neat device was developed years ago by U-Reely. It is in used but great condition and includes the steel lines that are wound in and out for storage.
I flew control line planes in the early 70″s and care of the expensive wire was paramount. It still is and this neat system protects your control lines from kinks by storing the lines inside.
Probably a vintage / collectors item but still works as well as the day it was made. You can choose your line length by the amount you reel out.
