Arcus vs

[[email protected]]

Hi,

How does Arcus compare (any and all aspects) to other modern two seaters?
Does anyone have any experience with Arcus EL?

Arcus is easy to fly, a bit harder to fly well.
Fantastic performance, as good as older open-class two-seaters.
Easy to deal with (rig/derig/taxi/take-off/land).
Duo better choice for lower time pilots but experienced pilots
have no problems flying mine.
I flew ASG-32 and Arcus prior buying ArcusM (formerly owned Duo share).

> Does anyone have any experience with Arcus EL?
Arcus EL is no longer offered.

If you fly one, you'll probably buy one ;-)

Hope that helps,
Best Regards, Dave

Why did you choose Arcus over ASG-32?

We really want electric self launch or at least sustained...

Enough power for high density altitude self-launch and self-retrieve,
sensible steerable tailwheel (actually steers and not broken when I test-flew),
IIRC bigger rear seat cockpit.

Be careful there is enough energy stored to do what you need.
Look at total climb altitude from a charge.

Hope that helps,

You may wait a long time for first hand information on the
Arcus E. However lots of generally good things are said about
the Arcus, Arcus T and Arcus M: there are lots of them at
Sisteron in the summer. The two stroke self launch Arcus M
and the Arcus E both have much higher wing loadings, opinion
on whether this is a real problem depends on who you ask.
Lots of information out there on the Lange Antares 20E/23E
electric propulsion system, this is pretty much the same as the
system in the Arcus E. In climb you've probably got 11 -13
minutes total engine run time so if you use 6 minutes climbing
out you've got 6 minutes of run time left; this is NOT going to
get you back from the far end of a failed 500K. This is probably
a significant factor for many buyers? On the plus side you have
a reliable electric motor not a complex smelly petrol engine.
I'd guess Dave Nadler would be your best source of
information.

So it looks like ASG-32 is the only electric powered two seater made nowadays?

Should make any decisions easy if electric engine is the base factor :)

IIRC only 3.

wing-tip into a rock-face, bad way to go...

There's one rented in Africa; google by whom and contact
them for information. They'll sell it to you ;-)

Yup!

ArcusM handles the weight just fine; not a big problem
even in pretty weak weather.

Bummer.

I have a nice Antares 20E I'll sell you after 2018 USA 18m nationals ;-)

Go for it! In America, land of the free, the Antares 20E can be
flown in both 18m and 20m mode. In Europe, land of the
actual designer and builder, only 20m mode is legal - go figure.

We have Arcus E in our airfield. Owners seem to be happy with it and it flies a lot and never lands out. It is very heavy which makes it impossible to fly in 20m class (800kg MTOW) competitions. All self-launchers in this class (and ASG 32EL which has similar empty weight) fly very close to 800kg MTOW without any water ballast. In WGC level competitions lighter Arcus T's (or those few non-engined ships) have edge in weak weather. I think the general consensus between 32Mi and Arcus M pilots is that both consider their ships to be little better than others...

[Craig Lowrie]

There is a third 20m flapped 2 seater worth considering... The 20m
TwinShark... Take a look on the HPH website.... www.hph.cz.

It is much lighter than the other two 20m flapped two seaters and has a
higher aspect ratio as well as latest generation aerodynamics.

If you are looking for a 20m 2 seater electric you may also consider the following

http://www.rs-uas.com/products/sk10e-elfin/preface/

the original manufacturer of the Stemme s10 but this is now a new company

Is that some sort of fuel driven engine turning a generator under the
left wing?Â* How can you call that an "electric"?Â* Seems to me they've
just put another layer of complexity between the gas and the prop.

BTW, I love my car gas fueled S10-VT.

The ASG-32 has a sustainer electric on a stick. If I am not mistaken this is technology developed in conjunction with the German government.

I didn't track, but I may have more time in 18m configuration.

Would not be a problem if manufacturer had completed certification as promised...

Some 18m tips are flown in Europe despite that ;-)
