RA 1643 (16%) and RA 1243.

Hello every body,
Hope you are doing well,
I'm at this moment trying to get the coordinates of the RA 1643 and the RA 1243 airfoils. I'm trying to do some simulations on the TB30 epsilon wing. I found that these airfoils are the ones it has but i can't find coordinates of them in order to have a model of the wing.
I have already tried the website http://airfoiltools.com/.
Thank you in advance and have a great day.

Here's another database with coords of different airfoils, but I couldn't find the one you want. : https://m-selig.ae.illinois.edu/ads/coord_database.html

You might have to get them from scientific literature done on this model of airfoil.
