Title: Nanchang Y-5 - A One Wing Biplane.
Post by: robunos on March 24, 2022, 06:42:35 AM

'Derived from the earlier Y-2, which was itself a copy of the Soviet Antonov An-2, the Nanchang Y-5 differed from the Y-2 by having a high, rather than a low wing. Built in quantity for the Chinese PLAAF, numerous examples were supplied to the North Vietnamese VPAF (Vietnam Peoples Air Force).
As well as their designed role as a transport / utility aircraft, several were used as nocturnal nuisance raiders, during the latter part of the Vietnam Conflict . . .'


cheers,
Robin.

Okay . . . some progress !
FIrst I assembled the upper wing parts,

then while that was drying down, I did the same with the lower wing . . .

when the upper wing was dry, I added the separate control surfaces.

While waiting for these parts to dry thoroughly, I built up the cockpit interior, and fitted it to one of the fuselage halves. I also added some of the windows, these will be painted over later.

I also CADed up and printed a batch of bombs, complete with racks.

Lastly for now, when the glue had dried fully, I cut of the lower wings, leaving just the centre-section.

Next I will add some scrap plastic and fair off the open ends.
That's All For Now, Stay Tuned . . .


cheers,
Robin.

That picture/event was my first thought as well!

Okay . . . some more progress !


I added scrap plastic to the lower centre-section and shaped it, here it is underway . . .

Two views of the glued up fuselage,

(https://i.postimg.cc/npb7z3LM/02-fus-done-2.jpg) (https://postimages.org/)


Dry fitting the lower centre-section to the fuselage revealed some large gaps, so I added plastic card strips to adjust the fit . . .


(https://i.postimg.cc/wqRyxN8h/02-fit-adjust.jpg) (https://postimages.org/)


then attached the lower centre-section.

Finally for this session, I fitted the tailplanes.

Okay . . . only a little more progress to report, but I have the wing on . . .

Wait, this is a 1.1 wing biplane!

Okay . . .
I saw the post in the Rules thread that we were past the half way point, so I thought I better get a wriggle on . . .
It doesn't help that I'm also currently down with the Lurgy !
Anyway, here we go . . .
I fitted the undercarriage legs. I'm not sure if the instructions are incorrect, or if the parts are not tooled correctly, but they don't fit very well, especially at the axle end of the main legs.

(https://i.postimg.cc/vYJy7c5f/03-undercart-2.jpg) (https://postimages.org/)


Never mind the paint job will help to hide it . . .


I also made some 'agricultural' bomb rack adaptors, to go on the wings. The idea is that these are something knocked up locally, to allow the attachment of salvaged bomb racks to the aeroplane. I will fit the bombs at the end.

(https://i.postimg.cc/BSLs1xPJ/03-bomb-racks-on.jpg) (https://postimages.org/)


Lastly, I painted inside the engine cowling black, fitted the painted engine, then attached it to the model, before giving the whole model a coat of primer.

Next stop is the Paint Shop.
That's All For Now, Stay Tuned . . .

Robin.

Coming along nicely Robin. I love your 'agricultural' bomb rack plates ... great touch  :smiley:

... I fitted the undercarriage legs. I'm not sure if the instructions are incorrect, or if the parts are not tooled correctly, but they don't fit very well, especially at the axle end of the main legs. ...

They look good in the photos.  And, for some reason, your stub wings are giving me a Nooduyn Norseman vibe. I like it  :smiley:

It's too late to do anything now, but I think the instructions are wrong with respect to the undercarriage struts, I think that the rear Vee should be at the front, and vice versa.
I noticed the Norseman look, too, I remember building the Matchbox kit as a young man. As I said, this is the easy option, I looked at not using the lower centre-section, and fairing in the fuselage, but it's a lot of effort for something that might not work out, plus I would have to scratch a new undercarriage . . .
Glad you like the bomb racks! They will carry the 3D printed bombs I made. I've also thought about adding underwing drop tanks, but that might be a bit too much . . .


cheers,
Robin.

And . . . we're finished !
VPAF (North Vietnamese Air Force) Nanchang Y-5 transport, modified as a nocturnal nuisance raider, Vietnam, 1977.

In order to carry out their new role as nocturnal nuisance raiders, the aircraft received modifications. Racks were fitted under the wings for the carriage of small bombs, dropped at random for their surpise and shock effect, rather than their destructive power.  The cabin windows were painted over, exept for one each side, which had the glazing removed, to allow guns to be fired, and grenades to be thrown, out of them.
A large exhaust pipe was also fitted, to muffle the engine noise, and increase the surprise of the attacks. Later missions however, were flown with the exhaust pipe fitted with a resonator, to increase the noise, as it had been discovered that the sound of the aircraft droning overhead was the most disturbing aspect of the mission.
On these later missions, the aircraft did not carry bombs, instead, a crew member would throw flashbang grenades out of the cabin window, as the Y-5 flew over an Allied Firebase.
Intensely annoying, the sleep-deprived Allied soldiers referred to these Y-5s as 'Skeeters' . . .


That's All, Folks . . .


cheers,
Robin.

Looks like a Soviet DHC Beaver! ;D



Needs floats! :D

Excellent work Robin. Attractive in a hyper-aggressive kind of way and beautifully finished  :smiley: :smiley:

Yep, and a 'King Beaver' at that!  But, being strutless, maybe a bit of Helio and Do 27 mixed in to the parentage?

And concur on the floats. For any Soviet version of the Nanchang, pontony (or skis?) would be essential  ;)
