Campgems, thats confusing. I am easily confused though. If the Lines aren't parallel. yet there's tension on both sides. I'm not seeing how one can go slack and on too tight. I believe it but don't understand it right now. When i went to spin my servo arm. i looked down my fuse with a flashlight and discovered both my lines had run around outside of formers[]. Soo i pulled them back out again and tried starting over without success. Iv'e tried fishing line put 8' through the back but couldn't get close too the cabin,tried making a hook to grab it from front moderate success, but already had gone around former.Also tried small galvanized wire,the supplied wire for fuel line + 18 awg solid wire. Might try that one again.thinking may have to get spare set of eyes with mirror and light "carlbecker". Or cut the covering soo i can see[].
