                               Considerations:
 
                    

An efficiency greater than 22 in the arc of 3 degrees, a minimum vertical speed of 0.81 m / s,
a landing
speed still manageable,
combined with a classic always a great choice of loading and wingspan
involving NRe finally aerodynamically convenient,
make a choice of 3.2m Swift hardly debatable.
The profile AB339-1.8 shows the best performance in flight but also in inverted flight,
compared to the S6061 that does not require presentations.
Available in the download section the polar dynamics of this project
also with S6061, for a possible comparison.
