The Sun is one of kite’s worst enemy, so if you are switching kite, or taking a long break, pack the kite instead of letting it exposed to sunshine for a long time (e.g. a few hours).
Always dry the kite before packing.
If you packed your kite wet in your last session (for whatever reason – it was raining / you did self-rescue but didn’t have enough time to get it dry before packing), and you don’t expect to kite again in a while (say 1-2 weeks), it’s better to take it out and dry under the sun and repack. It should take just 0.5-2 hours to get the kite completely dry.
Trimming your lines
I suggest checking your lines after every 10-15 sessions.
Why does the line’s evenness matter? After a few sessions of kiting, the lines (front lines and back lines) might get uneven due to either kiter’s habit (e.g. kiter likes to loop to kite on just one side), and line’s natural decay. A brand new bar should have all 2 front lines and 2 back lines the same length when the trimming line is at maximum power. The usual case is front lines gets longer than the back lines (so when you have the 4 line-tails lined up, maximum power trimmed, you pull the bar all the way in, there’ll be a distance between the bar and the chicken loop), the bar will tend to fly backwards (‘backstall’).
Another case is two front lines are not evened, see the photo below, the two center line are differed by just ~1cm..This 1cm difference looks trivial, it will alter the kite’s shape when flying,. When putting the kite at 12 o’clock, I found the bar significantly tilt to one side (as if one of the side lines was longer than the other, but in fact the back lines have the same length).
