These guys have been quietly building an electric machine for the past four years–work that has paid off by creating a salable drive train that can be used by other makers. After seeing pictures, I inquired with the usual questions and the lead developer, Pierre, was most helpful. Computer translators are remarkable, making up for my utter lack of foreign language skills and letting us communicate reasonably well.

ParaWatt’s story involves four “impassioned technicians” who have worked on the electric paramotor for more than 4 years, testing many existing motors, and finding nothing that approached what they wanted from a quality point of view of, reliability and safety. So they created one. The one in these pictures is their fifth prototype.

Here are the specifics, provided verbatim, from Pierre using a computer French-to-English Translator.

  • The price of the engine is of 1794 € and the price of the controller is of 699 €. We do not propose complete paramoteurs, but only the engine intended for manufacturers of paramotor or light ULM.
  • The price of battery 13S is approximately 1600 € at Kokam in Korea.
  • The maximum trust is of 55 kgF with a propeller of 130 cm. Note: I asked about a thrust/duration curve but they haven’t done that kind of testing yet. No worries, neither has anyone else.
  • The weight of our prototype is 31 kg, but it is a laboratory. I think that it is possible to make less than 30 kg ready for the use.
  • We have 14 kg of batteries.
  • Battery is a LiPo
  • Special Chargeur/eq
  • Special Chargeur/equilibror LiPo regulated over 4 hours charge.

The four team members are Pierre Renault, Louis Fourdan, Patrick Seme, Jean-Pierre Hochart. More pictures are available here.

FlyTec E-Drive

They’re not allowed to fly paramotors in Switzerland. And now that I’ve been there, it’s almost (not quite, but almost) understandable. A noisy motor would reverberate through any valley it flew in and, given that most of the country lives in valleys, that’s a lot of area. So they’re trying to get electric propulsion exempted and this looks like a good start. No info on sales or pricing yet.

Here’s more from their website.

Electric Trikebuggy

I got a bunch of letters about this one—a home-grown wheeled PPG by Pierre Beney. It’s built with off-the-shelf Radio Control model motors. Looking at the video doesn’t say much about it beyond the search for improvements. It doesn’t appear to have much of a climb rate but hey, it’s hefting the extra weight and drag of a cart so that’s not so surprising. One great aspect of rolling for takeoff is letting the wheels do the lifting. Batteries are heavy. Hopefully we can more details on this down the road.
