The first test flight of the Wing Load Research is successful done! Well, this was actually my second flight with the glider because I had to abort the first one when my helmet flew off (my mistake) and got entangled in the lines during the very first Rythmic SAT.
With my take-off weight of 93 kg the 12.5m2 has a trim speed of around 50 km/h under extremely high wing loading of 7,4 kg/m2!
The glider is super fast with extremely short and sensible brakes and violent reactions to any body movement. It works well dynamic moves, Rythmic SAT and Infinity but very difficult for the rest of the maneuvers, especially stalls and helicos. The G-Forces I measured during Infinity had maximum peaks of 7G which is actually the same what I am used to with 17m2.

The 12.5m2 is super fast with very short brakes. Works well for Infinity but very difficult to handle the rest of the maneuvers, especially stalls and helicos. Trimm speed between 48-50 km/h !
The Wing Load Research is my upcoming investigation to find out the real limits of the Thriller 2k11 from U-Turn which is claimed to be the best acro glider on the market.
I am going to test out the different sizes one by one while flying them on extremely high and low wing loadings, between 3,6 kg/m2 and 7,6 kg/m2 !!! For competitions and shows I normally fly the 17m2 Thriller at a wing loading of around 5.4 kg/m2 with 94 kg take-off weight. U-Turn's chief-designer, Ernst Strobl says with this take-off weight it should be possible to perform Infinity Tumbling even with 26m2, but regarding his theory it might not be the case at all with the 12m2 version, so let's see what happens! Beside that the wing-loading with 12.5m2 will reach way into the "red danger zone" by Strobl's calculation (see file "Table of area loading").
The main goal is of course to perform -almost- all existing maneuvers on the smallest and biggest available sizes of the Thriller. For the safe execution of the project this week I am heading to the Garda Lake in Italy to be able to do the experimentations high over water. Videos to come later on, stay tuned!
