If you go out with your 5 or 7 m2 kite, it can be flown in almost no wind at all - the smaller the kite, the less wind it needs
Beginners always mistakenly think that bigger kites can fly in less wind - but it is definitely quite opposite.
In 8-10 knots they are powered so you can usually just "park" the kite in the air - so easy.
But in 2 knots it can still be flown, when doing figure 8s or loops - quite amazing actually !
This is not possible with big kites, 12m2 and up - they can not fly in such low wind....
So a 3 or 4m2 LEI (not a trainer) could be used, and then you have a kite for the windy wavedays too
