The GP 15 JETA is our newest and most sophisticated, multitask 15 m, electric self-launcher up to date. Strongly focused on gliding performance, the design represents natural evolution of flawless GP 14 VELO platform, adopting very similar sleek fuselages in two sizes – standard and slim, as well as RESLS - 25 kW propulsion system. The wing and horizontal stabilizer are completely new designs. The highlights are aspect ratio of 29, unseen before in 15 m glider class and best L/D of over 50:1 (slim fuselage version). The new glider is a further step forward in terms of aerodynamic efficiency and use of carbon-epoxy composite technologies. Market introduction of this model is planned for first half of 2018. The glider is already available for order.
