TL Stream is one of the best ultralight airplanes available right now on the market. The airplane has been designed and manufactured by the European company TL-ultralight. By using the latest technologies and knowledge about aerodynamics this company has been able to design a beautiful and very low drag model inspired by jet fighter planes. Our 3D printed version is inspired by that model. However, many aerodynamic features such as wing airfoil, wing torsion, dihedral, decalage, CG etc... have been designed by us in order to improve its flight characteristics at low Reynold number. This model is a great sport model valid for a wide range of pilot levels, from intermediate to experienced.
