As far as I can tell, this wouldn't require huge ridges, high winds and extreme speeds. How tightly can you turn a sturdy DLG (or a foam wing) at a treeline?

Hi Tim,

yes, 2 min are very long, my site is very roughly and many trees try to catch the plane....
This is only a quick and dirty prototyp to test the aerodynamic. flies great and makes a lot of fun, but no ds possible, its not heavy enought at the moment. Vid from yesterday is here

Build it strong, stiff and heavy, about 1.8kg should do by the looks of it, and it should be a pocket rocket

Hi Tim,

we try again and again to fly DS with the Minirock, but as Jörg wrote the 24 g/dm² prototype is too light to survive the turbulence without a full stop.

Today I mounted 150 g under the skirt of the Minirock and attempted to break the new world record, but the conditions were only 2 Bft with crosswind and the best on video was 20 rounds in 2 minutes because of some thermaling in between

Perhaps i upload the 20 rounds-video at the thermal section

Here is a shorter video than 2 minutes with 28 g/dm², but the Minirock-prototype is not nearly as fast as your genius GIZMO:

Regards,

Uwe.
