Hippos are 25-50kg at birth, but they grow......
3x 180lb passengers (rear sitting same side as the hippo) plus a 110llb hippo (weight shared between front / rear seats equally for the purpose of calculation; though I suppose that is conservative as the weight will centre just behind the rear seat) and 25 gal (US) fuel, no doors gives you an all-up weight of 2281. Inside MAX all-up weight and both fwd (even with my conservative approach) and lateral CofG (according to a downloaded app called iBal).
Still not approved to lift with the skids. They are easily bent out of shape (don't ask how I know).
