Smooth and powerful, as you want.
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
Sonic is for those who are looking for a slightly more aggressive piloting but are not interested in the demands of XF15.
