I?d think you?d certainly want to dimple them for strength. We did that in drag cars and Pontiac did it on superduty frames in the 60s it degraded strength to the point they had to put 2x4s in the frames when they flipped them on the assembly line so they wouldn?t break.
I?d like to know more about the mod though.
It?s nice to have a light airplane, that?s for sure.
