Our Project


The All electric Aircraft

The e-Sling is based on the Sling TSi build by Sling Aircraft pty. Ltd. from Johannesburg, South Africa. Thus the e-Sling has familiar good handling, high versatility and stays close to the Kit aircraft market. With the modular battery system, innovative cooling, optional range extender and the electric motor developed with e+a the e-Sling is an one of a kind electric airplane.


Range: 250 km
span width: 10.5 m
MTOW: 950 kg
cruise veloc.: 160 km/h
passengers: 4

The e-Sling has a range of 250 km, with optional range extender up to 350 km can be reached. To increase the range we increased the span width to 10.5 m. This will enable more efficient travel for 4 passengers at 160 km/h. The e-Sling keeps the maximum take-off weight of 950 kg, to ease the certification.


Capacity: 50 kWh
Weight: 240 kg
Celltype: 21700

Our battery has a capacity of 50 kWh and is housed in the wings, instead of the petrol tank, and in the engine compartment. For the main battery and the range extender, Energy cells Type 21700 of the latest generation are used, cooled with our innovative cooling system.

Electric motor

power (max): 110 kW
power (cont.): 45 kW
weight: 20 kg
coefficent: 5.7 kW/kg

To meet the special needs of an elctric aircraft the motor will be designed by the students. The electric motor will achieve 110 kW maximal power for the start and 45 kW continues power during the cruise.
