To answer the issues of noise, fuel efficiency and
climb rate; as I stated in a previous post on this
thread, at 800-1000' AGL, the jet sailplane was much
quieter than the Cessna 175 camera plane. In fact,
I'd wager it's quieter than a rotary powered ASH-26.
Fuel burn is still high, but because of the jet's
preference for higher speeds, I'm able to cruise for
an hour at 95 MPH on 10 gallons. That's a fairly reasonable
9.5 MPG.

Climb rate is 450 ft/min at sea level (at 75 MPH).
I routinely self-launch from Moriarty at 6200' MSL
on hot summer afternoons.

I'll be the first to admit that the jet sailplane is
still under development. However, the engines are
improving at a rapid pace, and there are advatages
that are already very apparent, such as light weight,
low drag when starting/stopping, twin engine reliability
(yes, it will fly on one engine), no vibration and
a simple extend/retract sequence (soon to be a one-button
operation). The engines can be changed out in 15 minutes
with only a screwdriver and an allen wrench, and Fedexed
in a breadbox.

It really will roast a hot dog, and it really will
taste like jet-A. I just use lots of mustard, onions
and relish ;o)

That's the future for self launch.

Sure, once they figure out a way to make them quiet,
fuel efficient and with
a decent climb rate. I understand they'll roast a mean
hot dog, if you like
the flavor of Jet A (g).
