Kugisho Special Attacker Ohka model 11 MXY-7 1/72 scale

[Jinrai71]

I did very light washes with Tamiya panel line Accent Color Grey and AK Paneliner Black to improve its realism. As Ohkas were intended for one way mission it isn't logical to weather them, just a little is enough, they were factory new. The last part of the canopy was glued back.
I scratchbuilt new aileron mass balances, they were of unusual shape. Once the aileron is fully deflected the mass goes inside the wing via an oval opening, I think this is another way to prevent compressibility during final high speed dive.
I painted the pilot's seat gloss black, the lap belts were made with pieces of ordinary paper, with some parts painted in khaki other parts left as they are; buckles were made with plasticard (no photoetching, unfortunally - several tries were necessary). The whole assembly was then glued inside the cockpit.

The shoulder belt was particularly complex to make (it was made with the same technique as the lap ones), it required several parts and many buckles, once finished it was attached to the bulkhead/firewall. Did you notice the red rods inside the cockpit? Those were used to block the control column while the pilot seat was vacant during the flight, the pilot traveled in the mothership, he would only enter the Ohka when launching time was about to come. Once inside he would remove those in order to control the plane after launch.
The dolly was finished after glueing the belt to secure the Ohka in place, it was a photoetch part included in the Brengun set. I like so much how it looks!

The last detail I added was a tiny scratchbuilt propeller to its nose, its function is to arm the warhead. This little model was quite a challenge to make, but gave me lots of joy, IMHO the results were more than worth all the efforts!

Fantastic build! And the detail in such a small scale is mind blowing.

Final shots of the Ohka, resting in its dolly! Thanks everyone for watching the making of and for your appreciation!

Thank you very much!

tiny scratchbuilt

I think you're being redundant there.....
Well done, that's a work of art.

propeller

Impeller A propeller is powered and pulls or pushes the aircraft through the air, while an impeller is turned by air rushing past the plane

The model looks great, and with your hand in the photo it's even more obvious how tiny this thing actually was.

Psych!

Little did you know Jinrai is 7-foot 3-inches tall.

Thanks a lot!

Awesome build; hope it's not the last we get to see of your work!

no .
That's a prop , powered by the air rushing past it . like a windmill . A hub fitted with blades .
an impeller is a rotor like that used in a centrifugal pump . spun by a motor or other power source . the opposite of a turbine .

 

[Jakko]

We're both wrong I said impeller when I meant "turbine" — an impeller is indeed used to push fluid (or gas) around. However, the thing on the front of the Ohka is definitely not a propeller, because it's not used to pull the plane along but is turned by the air rushing past as the plane flies.

 

[urumomo]

no.
you've never seen a windmill , Jakko ? ( the irony )
You could also just google " bomb arming propeller "

 

[Jinrai71]

Ok, ok, then I'll restore the word propeller. English isn't my mother tongue...

Thanks so much! No, it isn't the last, I'm about to finish a couple of models, I just have organize the pictures then I'll open another thread. Stay tuned!

What do you mean, "no"? A propeller propels the thing it's on. A similar-looking device that's turned by the airstream is not a propeller because it doesn't propel the thing it's on. Per Wikipedia:

A turbine (/ˈtɜːrbaɪn/ or /ˈtɜːrbɪn/) (from the Greek τύρβη, tyrbē, or Latin turbo, meaning vortex)[1][2] is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work.

A windmill (one of which I can see if I step out of the front door, BTW) and a bomb-arming "propeller" do exactly that: they take energy from the air that flows by and use it to do work, whether that's to grind grain into flour or disable a safety device. They are therefore turbines. Whereas a propeller is a type of impeller, in that it causes a fluid flow rather than being turned by one.
