I have a small cessna that I spent quite a while making as light as possible so as to be able to to have just one propeller (highest thrust in consty's aircraft pack).

It floats great, it flies great but take off is always weak, ie I have to basically gryo-tilt back 45 degrees until the prop is essentially lifting the plane. The problem is drag from the water as I can't get speed above 29m/s, but I honestly can't see any way to float higher - the pontoons are made of nothing but panels and already as min-maxxed as possible.

Does anyone have any suggestions for somehow having less water drag?

Edit: I have a similar grid that is a boat that flies (where the cessna is a plane that floats) and it's just flagrantly overpowered with a single small grid large thruster. It easily makes ~60m/s in the water so when you want to transition to flying, even the vaguest of tilting up will do it.
