Are 100% electric ultralights around?

Jim I don't think that 30 minutes reserve is part of the 103
regulations. Personally I think this has huge potential as a
motorglider. I gave up hang gliding 20 years ago cuz I live in the
flatlands of southern ontario but I could easily see this plane in my
future.

Why do you think I am talking about a hang glider. I was answering a post
about a battery powered sonex. THAT has to have a 30 minute reserve.

I can imagine it now. You are about to land, and the plane in front of you
crashes on the runway. Now the airport is closed.

You say, "but you can't close the runway; my battery is almost out of
power."

You then proceed to crash into the farmer's field next to the airport,
destroying the plane, and severely injuring yourself.

A reserve is absolutely essential.

"Crash" is a strong word. I always land without a "reserve." It is usually
on a runway; however, a couple of times it was a farmers field. To date I
have never "crashed."

From the order this thread appeared in my inbox it appeared that you
were responding the the post that had a link to an electric trike

I'm surprised nobody has mentioned a commercially available
motorglider (self-launch) that can climb to over 10,000' on one
battery charge. Uses li-ion batteries in the wings and sells for just
a bit above $200k. Here is the website:
http://www.lange-flugzeugbau.com/htm...tares_20E.html
This is an excellent Open Class glider with a glide ratio of around
55:1 (of course with the engine retracted) and 66' of wingspan.

Herb, LS8-18

That we are now at the point where a tiny DC motor can put out 75hp, and
a battery that fits under that small cowling can make 50 hp for an hour,
is absolutely astonishing. In 1990 the idea would be considered
preposterous.

Too bad it's about $190,000 over my budget

That reminds me of the afternoon when we had several gliders in the air,
(some of them students) when a twin landed wheels up at the intersection of two
runways. The "powers that be" promptly announced that the airport was closed.
Long story short, nobody crashed, and nobody landed in any farmer's field.
Sometimes the pilot in command is really the "pilot in command" and has the
power to trump anybody on the ground to assure a safe flight.

Yep, you have a leg to stand on, in a situation like that, before the FAA.

Try telling them that you landed at a closed airport because you had no
reserve.

You had better be prepared to hand them your ticket for a month, or more.

Gliders have no reserve, and we had no other airport within range. In that
situation, we had not the slightest fear of the FAA. It was simply a matter of
the PIC choosing the safest place for the inevitable landing.

I guess I did not make myself clear enough.

I understand about gliders having to land, right now.

My point was, try telling the FAA that a NON glider could not divert or wait
for the airport to re-open because it had no reserve, and the pilot knew
there was no reserve, and see what they think of that.

Not too much, I'm guessing. g

Put the Sonex electric power plant in a Xenos
(http://www.sonexaircraft.com/aircraft/xenos.html); register it as a glider;
and, get a glider rating with a self launch log book endorsement. Problem
solved.
