Default Electric self-launch sailplane

Hello David,
your statement is only half correct.
since 2001 a modified DG is flying to prove
and test the electrical concept. I am not sure
if the Antares itself had now its maiden flight

A recent thread on this newsgroup asks if the "Silent" is the first
electrically powered self launch glider.

The prototype 20 meter Antares glider designed by Axel Lange flew in 2001
with NiMH batteries. The production prototype is flying with Li Ion
batteries. A friend just completed a 3 hour flight and is ecstatic about
both performance and the electrics.

A typical 60 amp-hour12 volt car battery stores 0.72 Kw-hrs
The Antares battery has 72 , 3.6 Volt, 39 amp-hour cells. It stores 10
Kw-Hrs
The motor delivers 42 Kw at 1900 RPM

The Engine Noise Level (ENL) detection system in the Cambridge GPS-NAV
successfully records Antares Propellor noise.

That just an opinion, it has not been determined by GFAC.

From the Model 10, 20 & 25 Approval document,


"B4.2. ENL during engine running....... but if an electric
engine is encountered, please contact GFAC as soon as possible so that
tests can be carried out."

The statement is correct - it is indeed the "real" Antares that had
its maiden flight a couple of weeks ago.

We'll get number #1 on our airfield...
