Well, we're not there yet. The ΦNIX is the electric version (the
blue one), but the tug in the video is actually regular petrol U-15, you can
clearly hear the good ol' engine. Personally I think the electric one has a
market for sailplane towing, but this option seems not yet available/certified.
You should ask directly to Martin to find out everything (storm.composites{at}seznam.cz).

Regarding your first post, the mgm-compro link is wrongly named "tug". The
electric project mentioned in the link is now developed and has become the ΦNIX
at pure-flight.eu. Unfortunately I don't find any video with the noise from
outside, they're all with music or from inside, but outside you have only the
propeller's noise, unlike in the tug video.
