How to cut weight of a wing tube ?
I have a 85cc Aeroworks Yak....looking to shave some weight from the wing tube (its 9oz).....a CF tube only saves 3 OZ....so I was wondering if you could drill holes in the factory tube to shed some weight ? Is the only load on the tube where the wing meets the fuse ? Is it possible to drill some holes in the middle and ends of the tube, and leave the area where wing meets the fuse solid ?
Anyone try this ?
