Just finished some new a-arms made from store-bought streamline tube. And then I saw those vile external brake-lines in place and I'm thinking... man, that probably creates as much drag and wake disturbance as regular round tubing would (if it didn't have a brake-line)!
So what is the trick to safely creating a portal so the lines can be thread through the aerotube? I know I've seen it, but can't remember what kind of stress-relief was done around the hole the brake-line would be fed into (and out of). A great big form-fit washer?
Also this, I'm using AN -3 lines and fittings, and their already attached to the braided ss/teflon lines. Is the trick to put the fittings on the lines post their being strung through the tubing? (That way, the holes would be quite small).
Has anyone been through this exercise?
Thanks,
Chris
PS: Funny how small your world becomes when you're thinking about things like parasitic drag. You start thinking in micro-vision. A radio antenna begins to look like a telephone pole, etc. !
