The UH-1 in service with the Dutch Naval Air Service (Marine Luchtvaartdienst) has always been an interesting looking helicopter to me, but unfortunately there are no options to build one in 1:48 scale. There are only two kits that come close to this version of the Huey, one very simplified kit from HobbyBoss and one from Monogram. That kit is well past its best-before date and is a waste of time, so I had to make do with the HobbyBoss UH-1C. The main problem was the exhaust section, which is very different on the AB-204. I 3D printed this part, and managed to fit it to the kit without too many problems. Since I was busy 3D printing anyways, I also decided to add some detail to the rather sparse HobbyBoss Huey. I printed new seats, a new rotor head, tail rotor, skids, flotation gear, mirror and various other small parts unique to the Dutch Huey. The model was then painted with MRP-225 and 040, and finished with custom decals. The end result is a unique rendition of this helicopter, and likely to be the only one in this scale. I hope you like it!
That is a beautiful model, a very unique version!!
Thank you, glad you like it!
Turned out beautifully… You might considder selling the parts you printed as a conversion kit!
It looks very, very nice. The same engine installation was used by the Swedish Air force and Army.
I would very much like to buy one or two sets of your engine parts if you are interested to sell.

Hallo Jasper, dit ziet er prachtig uit 
Deel/verkoop je het 3D ontwerp ook? Heel graag zou ik in contact met je komen. Mijn vader wil ook een Augusta Bell 204 maken van de MLD schaal 1/48 en is op zoek naar de uitlaatpijp. Ik heb een 3D printer en zou dit graag voor hem willen printen. Ik hoor graag van je.
Welcome to the site Nelly,
Not to put you off, but the working language on this site is English. This so that everyone can read it, and not just us Dutchies 
@Jasper_Breur what a fantastic result!!!, I just started building same project in 1/35 but also looking for the engine exhaust modification in 3d to not have to scratch build , and also need to make the decals. may I ask if you are open to selling/sharing the related files(3d & decals) ?
