Sonic is for those who are looking for a slightly more aggressive piloting but are not interested in the demands of Raptor or XF15.
nine cell semi-elliptical canopy of classical construction
openings are soft and consistent with minimal tendency to turn to the side
slightly cuted off the trailing edge for easier piloting and lower control force
aggressive at higher loadings, but gentle when lightly loaded, wide speed range
strongly held constant glide path
maximum lift force for landing
