The surface tension of the water is a larger effect than the quite low drag of short grass on the fuse. As I have posted, there are still some options around of adding a secondary step or larger step. Given the volume of water sheeting over the fuse, I also think spray rails will give some useful benefits.

The airfoil is a Clark Y variant, with a little washout in the tips and a couple of degress of positive AOA at the root.

The model has never quite gotten on step yet, so no way to know if the scale fuse design will allow it to rotate off the water, or not, once it gets on step.

I was already thinking about drooping the ailerons a bit, if it will not get off once on step. Will have to add a second aileron servo, as I have only one at present.

Never thought it would come close to taking off the water as I designed it...it was really a fun little scale jet for grass operations. But, who knows..It just might be possible.
