I have framed up a Shark .15 (Lew McFarland) from some old plans and am using .021" stranded lead out wire with 60# test, now I'm wandering if this is big enough wire? I have not joined the fuse and wing yet so changing it would not be totaly out of the question, but I REALLY don't want to hack up the sheeting on my wing. Is there a rule of thumb for lead out wire sizes I can use next time? Maybe I'm fine with the .021" 60# test?

Thanks,
David
