This is great!!
Now let's see how AlanG improves this model with his magic..

Sorry about that - bad hair day

I have now had a chance to look through the files, and observe a couple of things:

This model is indeed at an even larger scale than the other "Ultra-Realistic" ones - 1:4 instead of 1:5.5 - so as it stands it is enormous, very nearly half a metre long.

The parts count is somewhat lower than the recent UR ones, being around 630 for the "Standard Edition" and 550 for the "Special Edition", both on 34 pages. [The difference between the editions is almost all accounted for by the separate wheel spokes in the standard version, 36 on each wheel.] This is reasonable, as the bike itself is considerably simpler than the others.

The only differences I can see between the Standard and Special Editions are the wheels and chain. The standard version wheels have triangular-section paper spokes, whereas the special version has a frame for weaving a long cord between hub and rim. The standard chain has an L-shaped cross section, like those of the YZF-R1M and MT-10. The special chain is a box section with cutouts on the inner surface and reverse folds on the sides to allow it to flex.

I'm certainly looking forward to having a go at this one, which is a very nice departure from Yamaha's usual big macho prototypes, but I suspect it will be quite a tussle, as I shall be building it at less than 30% of the published size. I anticipate a fair amount of redrawing and some simplification to achieve something buildable. It won't be very soon, though, as I am currently finishing off another one of Akiro O's delightful small models, and then really must get on to Rupert Cordeux's Ely Cathedral which has been sitting on my shelf calling to me since June.

A good and prosperous New Year to you all.

Alan:

Thanks for taking the time to share your insight regarding this model.
Too bad you have pending projects, since, based on your observations, there are areas where it will be tough to re-scale to smaller scales, and I have seen your expertise on this, specially on the too-complicated-tubular-frames that you always manage to modify into more easy parts to build.

Well, I think I will give it a try at re-scaling it but only in the computer, since I still have to find a cure for my 'finish-a-project-phobia' that I've been suffering for the last 5 years.

BTW, are you going to post your work on Akiro O's model?

Best regards.
And Happy New Year to you all too!!

I use to want a real thing like that years ago.BSA Bantaam was the closest I ever found but in a lot worse shape than one on this picture.

Hi
i have the model rescaled to 1: 9

"ultra realistic"? might be pushing it a bit far...its definitely a paper looking model.
but its got a lot of nice paper details.

yeah, the special edition just has the different wheels and chain.
In my opinion, the paper spokes look a ton better than those string ones!

But those tires and rims are super wonky!! with their three overlapping sections.
And look how oddly deformed the back string spoked wheel is (in their photos)!
Whomever builds this needs to work on those wheels to improve the look.

this is how the cylinder with carburetor looks ready




length = 31.2 mm
Width = 18 mm
Height = 25.8 mm
Construction time 5 to 6 hours
