if the wind drops below the kites ability to keep in the air, it will backstall, no matter what kite it is. There are some kites which are more prone to backstalling but the solution is normally to sheet the bar out when it back stalls.

So many naughty kiters this year !!!

Santa gave the good kids in Perth 25+ knots today

Oh well - we'll just have to send a sympathy can of Baked beans for an extra knot or two

Xmas Cheers

Not sure what you're riding but if your back lines are too short you can easily choke the kite with a little bar pressure and it will back stall.

If your back lines are tight with the bar fully out then they are too short and you will not be able to stear the kite comfortably.

Maybe get someone with a little knowledge to check out the set up. You may need to get some leader lines to lengthen your back lines a bit. A few cm can make a lot of difference. If its a second hand kite sometimes people sell them with a bar that is not compatible with the kite and this can lead to problems.

Like what bigwave dave says is true also, play with the trim strap
