While you should be fine with the ESC ( Overkill with an ESC never hurts ) as the servos will at most only draw 1.5 to 1.8 A at worst....

The motor is a bit big for this plane.

The plane really only needs about 18A 250-350 Watts or so for almost unlimited verticals.

Heck I fly mine with a Frio which only draws 160 watts max.

You mention "throttle curve"... "this ain't no heli"... where that is applicable.

If you keep the prop size down though you will not draw more than 20-28A with say a 9x6E which is FAR more than enough for this plane.
