Hi! Kugisho MXY-6 motor glider for Shinden design.

Is there any reliable source of information on the color? In some pictures it's yellow; in others, it's orange.
I'm building it and finally just went for a compromise orangish yellow:

orange yellow

Thank you very much!

Here is how the project came out. Thanks again for your help!

To meet the IJN requirements of 1943, (18-shi-Otsu non-official specification) calling for a land-based, high-performance interceptor able to counter the new Allied fighters, Nakajima proposed the twin engine J5N1 Tenrai and Kawasaki the J6K1 Jinpu. Early in 1943 Lieutenant Commander Masaoki Tsuruno, of the First Naval Air Technical Arsenal, proposed the construction of a 18-shi-Otsu ‘canard’ fighter based on the information obtained on the Curtiss XP-55.

The Kaigun Koku Hombu ordered the firm Chigasaki Seizo K.K. the construction of three wooden experimental gliders MXY6, with ‘canard’ lifting surfaces, to prove the feasibility of the concept. Glider tests, towed by one Nakajima B5N bomber, began at Yokosuka in the fall of 1943, demonstrating good flight characteristics. One of the prototypes was finally fitted with a 22 hp Nihon Semi Ha-90/11 four-cylinder-boxer, air-cooled engine, driving a two-bladed wooden airscrew from a Kugisho MXY4 anti-aircraft target.

In 1945 the MXY6 was proposed to the IJN as a prototype suicide plane, but the project was not carried out because of the priority given to the construction of the Showa Toka bomber.

MXY6 3rd prototype technical data

Wingspan: 9.14 m, length: 7.3 m, height: 2.95 m, wing area: 17 sq. m, max weight: 500 kg, max speed: 320 kph.

Thanks for the drawings!

Holy "copying your enemy's worst ideas!"
Makes you wonder if Curtiss was sending Ascender drawings with the objective of messing with the Japanese.
Hah!
Hah!
I have wondered why both American and Japanese designers repeated the same mistakes.

Japanese engineers were wise to eliminate the problematic swept main wing from the Ascender. Two Ascender prototypes were lost to inverted spins.

Adding a powerful radial engine just added to handling problems. The asymmetric thrust influenced by turbulent airflow behind the stubby fuselage aggravated marginal handling characteristics.
To see what a successful Ascender or Shinden might have looked like, look at Burt Rutan's ARES experimental, ground-attack, canard airplane. Rutan moved the center of gravity far enough forward to heavily-load the canard. Rudders are mounted on booms that extend them far enough aft to effectively contribute to yaw stability and control. Rutan also eliminated most of the sweep in the main wing.
