I would guess both of my planes are slightly heavier than the projected weights but I am guessing the differences would be similar. The Orca definately has a little heavier wing loading unballasted. It also has a faster airfoil, that responds very well to camber. Also, the Xplorer airfoil when set neutral is slightly cambered similar to the airfoil used on the Zenith. I will try to get actual weights of my two planes to see how they compare to the projected weights.
My v-tail Orca weights 2000g. As a comparison Aspire has 79.9dm2 and weights 2250g and has a superior floating performance. I think Aspire would float better than Orca even when ballasted to 2500g... Airfoils are different, wing planforms are different, tails are different...
I would not compare Orca to Explorer. Orca is really a quite special F3J plane with F3B-like flavour. Its speciality is very good distance flight performance at low wing loadings.
