In the middle of the day, the air below 30' was very turbulent in the middle of the floor. I had a lot of trouble getting my F1L to launch without stalling and sliding back to the ground.

This is what we experienced in Belgrade (similar site with big windows in the ceiling and even more pronounced thermal activity). Based on my years of flying in calm sites, I avoided the "noon balloon" and opted for the calmer air times.

Treger, on the other hand, based, I assume, on his WC F1E experience, recognized the value of the thermals and built models that would handle them without pitching up and stalling.

My perception has changed :)
