Default Airfoil Suggestions

I am working on a long endurance UAV, and would rather not keep using the same old NACA 2412 I seem to be attached to, haha. I was wondering if you guys could give me some recommendations for airfoils to use. Here are the relevant numbers on the plane:

Reynolds range: 600k-800k
Endurance: 6 hours
Weight Loaded: 90 kg / 197 lb
Wingspan: 5m / 16.4 ft
AR: 10.0

I am just trying to get a better L/D than just a NACA 2412, that''s all, haha.

It''s naturally 8.897%, do you thicken it up? Is this good for root and tip? Thanks for the suggestion!

I''m not going to pretend that I have any expertise here. It''s just that the MH32 is a very efficient airfoil used on many high performance gliders and you were asking for a good L/D.
