Just looked at the specs. At 13kg and .93m sq area, I think the loading will be too much. Seeing as how I am now a 'USA' person, that translates to 98" wingspan; 1441sq" and 28.6 lbs. Not very impressive specs. You can build a Radiocraft Extra (103"; 1950 Sq") to around 23-24lbs with a BME 102.

Not sure what's available in SA, but I would hope you can import some good stuff.
