Front electric sustainer

[1] The system uses a 22 kW compact outrunner brushless DC electric motor located in the nose of the sailplane.

Heavier gliders can use it as a sustainer system, i.e. climb and cruise sufficiently high and far to avoid an out-landing.

[2] The one-metre diameter propeller is made of carbon fibre and folds across the nose.

They are slightly bent to take the shape of the front surface of the fuselage of each type of glider to which they are fitted.

Reinforced carrying cases are used to transport the battery packs to a location where they can be charged.
