So far, all this is in my head and need the wings for final drawing. A long 3/8 "brass tube, similar to what I use as shaft tubes for my boats, sharpened at the end will be used to hollow out the path for the wires. I will post pictures of project when done. Plane is due to arrive next Tue. But first I have to let my fingers heal. Dont know how as it happened so fast, but on the 8th, my Seamaster attacked my fingers while on the ground, getting ready for another flight, just sitting there and warming up. Next thing I know, I got four of my fingers cut. After 10 stitches and a glass of wine, it felt better. First time in 15 yrs and hope to be the last. The plane and APC prop is ok. The motor never even slowed.
