Helix makes props primarily but they have been dabbling in electrics for a while now.
No recent news from Helix but some old bits:

First flight with Proton 1.1
On 23.02.2007 Richard Krüger-Sprengel does his first flight with the actual stage of electric paramotor Proton 1.1. This version of paramotor has a smaller propeller. The diameter was minimized on 1,40m.
The flight was accomplished at bad weather conditions (wind of 30 km/h).
Short facts:
Measured data on ground before flight full load:
Battery voltage: 44V
Discharge current: 176 A / 7,744 kw
Propeller: 2450 rpm
Measurement of H25F 1,40m R-S-05-2 torque 29,1 Nm / static thrust 49,4 kp

Helix exposes prototype of electric paramotor on Coupe Icare in Saint Hilaire:
In the context of the exhibition on Coupe Icare Helix shows his Prototye of electric paramotor. Richard Krüger-Sprengel the developer of the
prototype has shown that electric paragliding is possible and will be the future. The greate feedback and resonace on the prototype stengthen
Krüger-Sprengel in his opininon. He is in close contact to several developer teams who are working on electric paramotors.
Richard Krüger-Sprengel is going to install a yearly meeting for electric paramotors, to have a platform for exchange of ideas and to
show inovations. For 2007 it is planned to imply that meeting into the german paramotor championship in Krahwinkel (15.-20.05.2007) to show the
state of the art to a wide audience.
