Im confused...

the kadet lt 40 specs
SPECS: Wingspan: 70"
Wing Area: 900 sq in
Wing Loading: 14-15 oz/sq ft
Weight: 5.5 to 6 lb
Length: 56"

the electristar specs
Wingspan: 63" (1600mm)
Wing Area: 709 sq in (45.7 sq dm)
Weight: 6 lb (2722g)
Wing loading: 19.2 oz/sq ft (59 g/sq dm)
Length: 53" (1346mm)
Center of Gravity (CG): 3.5" (89mm) measured from the forward edge of the wing at the fuselage sides

When comparing those specs, how is it possible that the kadet would be anemic when the electristar is fairly spirited?
Unless the specs on the electristar are including motor and battery weight and the specs on the kadet are just for the ARF, not power system.
