Default gambit mesh about a wing

Can somebody give some suggestion in generating a mesh using gambit for a typical external flow problem (RANS), say an Onera M6 wing?

My particular problem is the bundary layer mesh around aerofoil trailing edge. Whilst the b.l. function seems to give reasonably well behave cell around the region, the actual mesher always produce distorted cell. (I need y+<=5 for the first b.l. which translate to y<=2e-6 for typical problem)

I've seen the potential offered by size function that is availabe in v.2.0, but I can not managed to get a grid with similar cell distribution from those of vgridns or centaur. Again, it is the TE region that seems to be the problem.
