As a 'Motorglider':
(ii) Maximum weight does not exceed 850 kg (1874 pounds);
and
(iii) The maximum weight to wing span squared (w/b2) does not exceed 3.0
kg/M2 (0.62 lb./ft.2).

500 lbs MTOW
and
28.5 ft wingspan = 812 (wing span squared)

500 lbs MTOW (/) 812 = 0.61576 lb./ft.2

....which does not exceed 0.62!

So yes, it is a motorglider

....IF the MTOW is 500 lbs
....or we go with longer wings
....or we follow the first link. <g>
