Im using the MR scale clevises that came in the kit. I have to backup. I was just looking at MRs web and maybe he is unwinding the flying wire to clevis and leaving the screws that attach them to the airframe brackets. One side of his flying wire setup has no adjustment, so it will just spin. Unwinding the wire will only pull out one end. I was thinking that he was taking the small screw out and pulling the wire to line everything up before putting in the screw. which is an option, but they are small. The problem with a real turnbuckle is both sides will unwind, making it a little more fiddly. Hmmm.
