sorry for this ON-TOPIC *gasp* post *g*:
pulled off the Avweb newsletter:


I wonder if 25,000-ft is for quicker certification and they'll end up
applying for higher certification at a later date? Cirrus did that with
their composite airframe life numbers.

Still wondering...

I wonder how much lighter the D-Jet would be using this system?

A MUST READ!!! :-)

"Composites are much better than aluminum, which has been used in the
aerospace industry since the 1930s," Blue asserted. He said composites are
the reason that Spectrum can develop a 10-seat twinjet with an mtow of 7,300
pounds. According to Blue, the Model 33's one-piece fuselage, complete with
integrated window and door frames, weighs a mere 309 pounds. The aircraft's
single-piece, "co-cured" wing weighs just 305 pounds."

Screw the 10 place jet - Spectrum 33 (kidding, kidding, kidding)

Screw the D-Jet/Eclipse/Mustang 4-6 seat group. (still kidding)

Give me Spectrum's construction methods (link), with a single (mini)
HondaJet engine, on a mini D-Jet single seat platform. I'm telling you
there's a market out there for this!! (Not kidding)

I'm guessing you're looking at a 300 lb plane - using the Spectrum #'s in
the link.

Single-piece wing .......40 lbs.
One-piece fuselage ... 40 lbs.

Engine ....................... 150 lbs(?) ...200 lbs(?)

[1,568-pound-thrust Williams FJ33-4A = 290 lbs]

[1,670-pound-thrust HF118 = 392 lbs] Super quiet! Too heavy.

What's left? ...................70 lbs. (At the very most!)
Total Empty Weight ....300 lbs. :-)))))

[450 lb. Empty Weight with an off the shelf Williams FJ33-4A engine - too
much engine? g]

D-Jet + Cri-Cri + Star Trek 4's Transparent Aluminum + the reliability of
Honda.
