Propeller:
The team originally hoped it would be able to find a suitable commercially available propeller -- it has pretty much given up such hope and is resigned to building it's own from scratch.
~ specs:
Number of blades = 2
Diameter = 16ft
Pitch = 100in
Prop will be similar to those used in a variety of human powered craft -- foam core over carbon or aluminum spar, covered with a composite skin.
We will need to build a hub which allows for minor pitch adjustments for optimization between runs (true pitch adjustments can only be made throgh the production of an entirely new prop.
