Hi all.

I´m considering building a BUSA 1:3 Super Cub, and my plan is to incorporate some of the mods used on the full size STOL versions. Maybe extended squared wing, with bigger flaps and ailerons, and other cosmetic mods.
As far as I know the full size community is impressed by the performance when adding vortex generators, and I´m thinking that this may also work on model sizes?

At first I considered buying a "generic" VG set, made for ultralights, but they are going to be rather large and clumsy for a 1:3 scale, so I may have them 3D printed in nylon by a friend with access to all the fancy toys, and made in a more appropiate size.

But I´m not even sure if they will work as advertised when scaled down. Anyone with relevant experiences?
Can I use full size formulas for placement, or do I need to make changes due to the smaller wing chord?

Thanks in advance.
