Wilga is my third homemade/ DIY RC model, I built in in 2013. Some have request for me to release the build video. The first version is very detailed and very hard to make, especially the tail boom part, because in the first version the tail boom is fully cylindrical. It's also quite heavy around 1200 gram, so in this latest version I already made the plans easier to build and only has 900 gram AUW even with larger wing area. The first one is 1300 mm this one is 1400 mm wingspan. However the test flying was not very smooth, there were some trials and also a crash. But luckily it was easy to repair and I made the nose a bit longer to remove the heavier counter weight ballast.

Specs :
1. Wingspan 1400mm / 55 inches
2. Flying weight : 900 grams/ 31.7 oz
3. Wing loading : 35.7 g/dm2 - 11.7 oz/sq.ft
4. Wing cube loading : 7.1
5. Wing Area : 25.2 dm2 / 391 sq.in
6. CG : 5.25 cm from LE
