Can i make the ailerons work with the elevator, but still work like ailerons at the same time.I know this maybe a rookie question, but i am.at trying 3d anyway. any help would be greatly appreciated

Set up the ailerons on the Flapperon mix. Then set up the elevator to flap mix.

Just be sure you're not doing things that aren't necessary. The 3D stuff is done mostly through pilot skill and not fancy mixes. Get as close as you can with just your thumbs a maybe a little expo then work in flaperons, spoilerons, whatever else'r'ons.
