Most complex model

dup

This is the monster that Durr refers to.And yes it is un-necessarily complicated!   

I got a model that is worth looking at. It's not my model, but it is still interesting (and complex)

It's a 1/40 scale model of the F/V Time Bandit (of Deadliest Catch fame) completely scratch-built and radio-controled. Martin Bak, the builder, completely scratch-built everything.

Here's the link (I highly recommend looking) : http://www.timebandit.tv/martin-boat-model.html

This has given me an idea: why not scratch-build a model of every ship on Deadliest Catch? 

the most complex  i know is the over engineered icm  tb3  bomber with parisite fighters each of it's 4 eng nacelles come complette with Full engines  and  you build the intire plane  as the real one a compplete frame/skeliton  the you lay the aitcraft's skin over that 

The only one that comes to my mind are some kits I still have to build (not started) If they count, then they will be an old AMT/Eartl 1/25 scale ladder truck (with lots of scratch-built goodies) and a Monogram Ford F-250 (with a scratch-built bed and details to make it into a fire truck)

The most complex model I've accually got done and completed is the KV-1 model from Zenvino (I'm not sure of the spelling. It's that manufacturer from Russia)

WOW... !

Marder II w/ Soviet 76.2mm pac 36(r). Everything above the fenders was modified or scratch built. The gun features a open bore modeled around a 1/8 aluminum tube, turned on a drill & taper achieved with Tamiya putty. The indi- track links had 5 pour stubs each! @ aprox 94 links / side this alone consisted of dozens of hours of clean-up. The 1 piece molded gun cleaner was scratch built out of hypodermic needles & wood brackets. Most stowage equipment was scratch built as well, including a tripod for a MG-34.

Most complex model kit definitely belongs to ship..

Some complex ship comes with PE can easily surpassed 1000marks parts.

Mine was Academys 1/32 F-18D that i built for my bro(F-18D WSO). I ended up adding around 75 tiny bits of detail to the pit alone, 30 someodd bits to the nose gear, mains were in the 20s. The kit has 500 some odd parts, almost half of which are ordnance and option parts, I ended up somewhere in the 500-600 range.

AHhh...mm,,, 2 most recent kits got to me.. almost.. an Italeri Panzer MK IV, it was my first armor kit in 25 yrs.. I went a bit crazy and got PE, resin, metal barrel.. etc.. Indi tracks... It came out very well and even took a 1st at Downestcon,, but It was wearing me thin in the end... first time indie tracks.. to much overload with the roadwheels... and extras..... shortly after that, I started Tamiya's Pershing,, same thing again.. with a full engine bay/tranny bay.. lots of PE.. metal barrel... I alomst set this aside many times.. but I managed and finished it..

In the end.. it was worth it,,,, but in the process, it was mind bending...

in the mean time.. I completed 2 Bandia Starblazers battleships,, small parts count.. easy painting..

I would guess the most complex model I ever built, including all the PE and aftermarket) was probably in the upper hundreds for parts (say 700).  I do have the DML PzIV 3-in-1 on my shelf with a parts count around 1400.

None of my attempts would even come close, though.  I think I've seen some articles in FSM with those crazyily detailed, scratchbuilt, superdetailed builds that have parts counts in the 10's of thousands...
