On the handling I agree...the center o gravity (cg) is long before the nutral point of the wing...so the plane is more responsive to the controls like having the CG moved a little back on normal configuration.
In Rc-sailplanes we move back the CG just a little before the plane is unstable to have faster turning and good acro..
On the side of efficiency I don't agree so much.
Most of the airfoils fly "better" with the cg on 25/30% of the mean aerodynamic chord ...for autostable foils we are around 12/17%.
In a canard configuration the Cg is really near the leading edge of the wing...so rotating moment would be very high and the stab would need a very big longitudinal anhedral to compensate...


Also I seem to remember to have read they cannot have flaps

I would love to had seen it with a pair of bmw 003d.

Looks to me like it has "Engine Overheat" written all over it.

I Love the Shinden! I don't care how many problems it had. It's just the design I love. I play a video game where you can buy a shinden to fly. It's for the NDS it's called Freedom Wings. Everyone says it stinks, but I like it just the same. Thanks for posting that painting, Aggie 08. I'm keeping that one. It's the picture in my desktop now.

I've seen that one b4, comiso. I was researching the plane and came across the video in this forum. Interesting nontheless!

I'd forgotten about this thread. Thanks to Hartmann for crediting that beautiful painting to Koike Shigeo. It really is an awesome image.

I wonder if it would have been more susceptible to battle damage as the engine would likely be the first part of the plane hit in air to air combat.

[F4F Wildcat]

Oh, yeah... Hadn't thought about that. I still love that machine.
I hope I can get to the Smithsonian to see it for myself.
Well, thanks Hartmann for finding that painting. It's beautiful.

I wonder if the American changing B29 tactics from High altitude bombing to low altitude affect Japanese aircraft development. I can see the Shinden being useful if it has to climb to high altitude but I think it would get chewed up by escorts at lowers altitudes .

I've been researching this plane a lot, so I've seen that one b4.

What about the colors of these plane ?

I try on Japanese Green, Japanese Gray (Tamiya Paints...)

Thats it ??

Thanks for sharing ! Nice pics and links !

Funny you should ask Lucas,

I was curious as to the finish on the LG doors and bays and wrote to the Smithsonian to ask about it. What I got back was a partial copy of the restoration guidlines (dated 25 October 1983!) authored by none other then Mr Robert C. Mikesh, Senior Curator. Interesting stuff.

Here are his paint suggestions;

External, upper: Black Green (N.1) Munsell 10 GY 2/2
External, lower surfaces, wheel wells and covers: Light Gray (N.10) Munsell 7.5/
Propeller and spinner: Brown (N.12) Munsell 10 R 2/3
Wing leading edge and propeller tip markings: Yellow (N.14) Munsell 10 YR 7/14
Insignia and warning: Red (N.20) Munsell 5 R 4/12
Cockpit: Interior Green (N.5) 10 Y 4/4
Landing Gear: Flat Black

Enjoy!

Regards, Jim

Nice Informations Jim !

I like to build a plastic model of this beauty, the hasegawa has a good kit on 1/72..

Great information, I could swear that the interior colors was Aotake...

Thanks for sharing !

Best regards,
