High point--C of G--bolt Hole position ???
My home made blades fly OK, but I'am wondering what position people like to put their C of G and Blade Holes in relation to the "Highest point"[max thickness of chord point] of their blades?
My holes are on the "highest point"[apx 30% from leading eadge], and my C of G is apx 10% behind the bolt holes[apx 40% from leading eadge].
They are all balsa blades[no harder/denser wood in LE].
Wondering how other people set theirs up??

You want your bolt hole on the highest point, but you want your CG to be in the same spot. So either you need to add weight to the LE of your blades or move your hole back.
My two cents.

I think the blades will not center very well. For example if the CG of the blades if forward of the hole, the blades will not swing straight out but instead slightly forward. (I think I have that right). Anyway, you want them close to the hole. You should be able to just add a little strapping tape to the LE to get the CG more forward.....worth a try!
