VG, a slight correction. The fat symmetrical airfoils typically used on stunt, sport stunt and combat models will be very gentle at slow speeds. The thickness of these airfoils delays and softens the final stall to the point where they are very easy to fly slowly and give good warning before the break.

These same characteristics show up on the old "fat winged" fun fly models popular a decade or so back.

And of course as with any model a light overall weight to give a lower wing loading value goes a long way to helping.
