North Wing Sports offers a range of parts for pilots building their own 2-place . Figure 1 The faster plane influences a larger volume of air in a fixed time, so the wing does not have to work as hard to generate the same amount of lift. Exactly why that's a good thing is not completely clear, but in the US at least an ultralight must not be able to exceed 55 knots in sustained level flight.
