The pylon raises from the back of the bay. The motor pivots on the pylon so the
thrust axis is always horizontal.
See https://www.facebook.com/gpgliders/videos for a number of clips of the
motor in action.

Any good links?
I found a schematic diagram which indicates that the motor has a pusher
folding prop. Not sure how it retracts and fits in the fuselage with the
blades sticking up?

Yes, Matt.
Mainly that the limited diameter of the prop limits prop efficiency.
In the chain Battery->motor->prop-> useful thrust, prop efficiency
is the single largest loss. You'll get around 50% at the
power/diameter/airspeeds we are dealing with here. More blades aren't
necessarily better

There was an electric Silent 1 for sale in around 2007. The Antares
was the first heavyweight production glider. From memory, the original
Silent had a pylon mounted motor.
So far as solar panels go at night… most flying
you just put nice bright lights on the solar panels at night…simple :-)

LOL! Good point. You might need a Honda generator
running most of the night. Yep, clean green motorgliding.
Lange Antares has been around for a while. I
think it was the first PRODUCTION electric SLG.
Uses some Saft V44 Li-ion cells. 72 of them I
think. Lots of very careful cell management i
Umm. I believe solar panels don't work so well overnight.
Not in australia anyway 😜

HA,
There's an interesting article in the current S&G about a casual comp
done in Italy, flown with the Silent Electro. Was this the world's
first electric SLG? I know it proceeded things like the Antares by
almost a decade.
Anyway, the innovation with the comp was that they were allowed to use

Even with the new battery tech you'll only get
about 1 hour endurance at cruise power (65%)if
you replace the Rotax and max (optional 31.7 US gallons) fuel.
Nice self launcher with good retrieve capability
but you lose the "travelling motor glider" bit.
With electric it is probably not optim
I did read last week that Apple are testing new Lipo anode design right now
that gives twice current capacity at same weight and size.

“What he said” - I’m curious about that too.
Brand, $$, availability, and (importantly, also) size?
My long term dream is to throw the Rotax 914F out of my Stemme and replace it
with batteries and an electric motor, and if a combination of both existed that
had roughly the same total mass, th
What new battery technology is that?
