Hi,

For me about 10 flights if others at the field that I want to talk with etc.
If I'm alone at the field and I'm really hungry for flying it can be up to 20 flights but it is not that often I'm alone at the field.
It is better to fly fewer flights and concentrate on these flights really. Quality goes before quantity.
But sometimes it is just so fun to fly I just fly, land, change battery, fly, land (charge LiPo), change battery, fly etc until
I have no more source batteries to charge with (I have two 80 Ah lead batteries with me usually to the field as source batteris for charging my LiPo batteries).
