Kite is really stable up to about 25mph does become a hand full in anything more (although i can still hold on to it as it has loads of depower)than this but any wind range between 10mph to 20mph it works fine. if wind gust the kite just tend to fly further forward than settle back although cant say its ever been that gusty in winds under 20mph & if wind was gusting more than 20 id rather go for a smaller kite.
