Prototype ElectroLight 2 is a demonstrator made by ELECTRAVIA. It allows to implement the many innovations developped by the company : electric engines (E-MOTOR), controller with recharge, silent propellers E-PROPS, motors & batteries insruments E-SCREEN, BMS & PCM for LiPo batteries, special optimized engine fairings in order to reduce form drag and interference drag and optimize system's performances.
ElectroLight 2 is a nice and silent motorglider, simple to fly, very reliable and economic. With a Lithium-Polymer pack of 5,55 kWh (34 kg), the flight range is 1h35 and the altitude gain about 3.000 m @ best glide ratio speed (90 km/h).
ELECTRAVIA is selling the whole electric propulsion system [electric engines, controllers, batteries, instruments, propellers], and can implement the system on a strong and light glider's airframe. See prices of the ElectroLight2 below.
Wings are in wood, fuselage in welded mesh
