Hey guys thought I would post my home made pull pull sys. I made for my Model Tech Magic Extra 300L. The kit comes with a hard wire pull pull system but there could be some binding i think in the servo with the hard wire set up so i went to my local Hardware store and bought a small package of braided steal wire that is used for hanging pictures. its flexable enough and light weight and should have just enough streaching for there to not be any binding on the servo. then I used 2 of the metal (duo bro with the little clips) for your control serfaces on a piece of threaded 256 wire screwed together like this

===-------===

then attached the one side to the control horn and ran the wire through the other end and used a crimp and you have good adjustable end. and for the other end I used the same duo bro metal end and where you would thread you control rod in just ran the wire in and back and crimped. I would post a pic for you to see but not to sure how to post pics in the fourms. it works good for me and there dont seam to be any problems with this set up for me I have 6 flights so far with this set up and did not seem to loosen any and no binding on the servo. good luck all and have fun flying I know I do.
