Andor,

In a perfect world...I win the lottery and have one parked in the
hanger next to my brand new Extra 300.

Very nice video -- nice video editing! I'll risk being
considered picky by saying I would prefer music without
drums or a strong beat. Soaring is just not that mechanistic.
I have few ideas about what music I would put with
a soaring video, even though I'm a musicologist. Probably
it should be composed for the specific video just as
film music is done. Come to think of it, there is
one string quartet by a Mexican composer, Javier Alvarez,
written for the dedication of a subway station that
would be good. 'Metro Chabacano.' It does have a
beat, but there are no drums. The rhythms are so kaleidoscopic
that they could easily represent both the flow and
the unexpectedness in soaring. ( Recorded by Cuarteto
Latinoamericano. Still in print, if anyone is interested.)

Well, Google has failed me :-(. Just how much does the Antares battery
pack weigh and how long for a full recharge?

This lists the charging time as 8 hours at 220 volts:

I believe the batteries are permanently mounted in the wings, and the
likely weight of the wings is suggested by an glider empty weight of
just over 1000 pounds (20 meter span), as compared to an advertised
empty weight of 605 pounds for the pure glider in the 18 meter mode.
You won't be lifting these wings.

Included in the Antare's price is an *excellent* one-person rigging
system.
There's no need to be lifting the wings !

All of the one-person devices I have seen require you to lift the tip
end of the wing. It is my impression that you can't do that with the
Antares wing (too heavy). I am curious -- Is there a photo of this
one-person device, or a description of how its works?

Hi Greg - You do lift the end of the wing, and its not too heavy - I
tried it. I'll post my blog on Antares one of these days after I clean
it up, will include info on the rigging gizmo...

So the batteries must be inboard on the wing, close to the fuselage.

Where else would you expect them? Handling would not be improved by
moving them outboard and there would be increased wiring losses in the
power system.

Huh ? Bending moment ? Minimize losses by using high voltage/low
amperage ?
Anyway, handles great, and easy to assemble.

Well, there must be a reason that some gliders require you to use the
outboard tanks when you are flying with partial water.

Hi,

You can see more Antares images and videos here:

I hope to be able to afford one some day...

Hello everybody,
I apoligize for not answering your questions earlier,
life is rather busy here.

The movies:
They are very much a one man production by our engineer,
test-pilot, camera man, movie director and musician
Ola Roer Thorsen. Copyrighted music could not be utilized,
but we still think the result is acceptable :)

Charging:
A full charge takes 9 hours, using the integrated charger.
A full charge costs less than 2 euro, and gives you
more than 3000m
climb (depending on aircraft weight). Partial charges
and discharges are no problem, as the batteries have
no memory-effect.

Rigging:
The batteries are positioned in front of the wing spar,
filling the volume from the wing root and approximately
3.2 m outwards.
This minimizes negative effects on aircraft inertia.

Add to this the novel control system used in the Antares,
and the result is a surprisingly agile glider, with
handling close to that of a 15m glider. Based on this,
I am curious as to how the 18m Antares will handle
when carrying no water.

Each wing of the Anmtares 20E weighs approximately
120 kg including batteries. In order to get the wing
out of the trailer and into the rigging aid, the pilot
handles the wingtip, lifting maximally 30 kg, and usually
only for 20-30 seconds.
The rigging aid grips the wing at its cg, and uses
a gas-spring to ballance the wing vertically. This
makes it possible to rig the Antares 20E single handedly
without breaking a sweath.
Actually it surprices me how much work it is rig a
'normal' glider..
I guess I am a bit spoiled :)

Speaking of batteries..
In order to create volume for the batteries in the
20E, the spar is positioned markedly rearward of its
normal position. This feature also pays off in the
18m glider, resulting in a marked increase in water
ballast capacity, which is one of the reasons why we
expect it to become a very fast glider. The coming
season will be very interresting indeed.

Ok. I hope that that answered some of your questions.


I wish you all very politically correct happy holidays.

Andor
