Thermal collection, kmz files
3-4 m/s thermals
2-3 m/s thermals
1-2 m/s thermals
One has to first check with the local pilots if it is ok to use it. It has a much longer recovery compared to Dasklip takeoff.

> Angelo and Gary V had since landed not far from there. The air was

> all the way to 1400 ASL, where I twice left the climb in disgust to go and
> sort out my ruffled tail feathers.

> Because of my lethargic state I got a quick wake-up call early on in the

> when I wanted to carry on, I was hunting desperately low.
> But the gods saved me and trigger point after trigger point delivered. The

> I tried keeping a manageable vector towards Eendekuil, and tried
