D3K Posted January 3, 2015 I've been wanting to make this since I got back into Lego roughly two years ago, and had just started playing around with a road wheel setup for it when [TC6] was announced! Firstly here are a couple pictures of the real vehicle in Norwegian service If you google CV9030 you'll find tons more Obviously building this in studless Technic is out of the question, so I am currently in the process of building my first studded MOC in around 20 years! It is also an all time first building a military tracked vehicle, as well as something studded based on a real vehicle, as well as building PF into a studded model. I want to make it fairly small, so small track links it is (I hope to one day make a properly detailed model of the same vehicle in larger scale using the new style tracks). Anyway, seeing as 99% of my studded brick collection has been sat in the same place collecting dust for the past 15-20 years, I'm rather handicapped both in parts selection as well as colour: As you can see, it's not ideal by any standards. Building studded is so different from studless, it feels almost like two completely different toys! I'm going to have to redesign the transmission, and possibly relocate the motors. The space inside between the suspension "rubber band arms" is only 4 studs. Although the real CV90 uses torsion bar suspension, using that at this small scale would be way too stiff, and thus not make any sense. I will much rather have functional, soft suspension, as you can see in the above picture. So, that's it for now, still quite a way to go as you can see I will do a lot of tinkering in LDD with regards to the turret design, and hopefully the final physical model will be either LBG or white (like the ones in UN service).

Lakop Posted January 3, 2015 (edited) I love this. It looks great despite the minor issues with colour. I love the drive set up. Keep at it. H Edited January 3, 2015 by Horace T Share this post Link to post Share on other sites
Kelkschiz Posted January 4, 2015 Looking to become a snappy little AFV. I like it! A question if you don't mind, what are all those gears for in the middle. I have been looking at them but i can't quite figure it out. Share this post Link to post Share on other sites
Tommy Styrvoky Posted January 4, 2015 Yay, another AFV, it looks great so far, but how do you plan to use the other 2 functions of the Sbrick, will there be enough space for another IR receiver in the hull, or will it be put in the turret ? Share this post Link to post Share on other sites
D3K Posted January 4, 2015 Looking to become a snappy little AFV. I like it! A question if you don't mind, what are all those gears for in the middle. I have been looking at them but i can't quite figure it out. It's the only way I have been able to fit in a reduction in the gear train, and yes; it uses an enormous amount of space!! I think I'm going to just have the motors geared 1:1, and use the variable speed control the SBrick offers to regulate speed.. high top speed is nice as well you know! Yay, another AFV, it looks great so far, but how do you plan to use the other 2 functions of the Sbrick, will there be enough space for another IR receiver in the hull, or will it be put in the turret ? This is a very early rendition of the layout, I'm pretty sure I'm going to move the motors further up front as well as drastically reduce the number of gears, thereby freeing more space. I'm thinking of using micromotors for turret traverse and elevation due to the lack of space. The placement of the IR receivers is also something I haven't decided yet, we'll see where there is room Share this post Link to post Share on other sites

emilstorm Posted January 4, 2015 It looks really good so far, and nice to see some of those good old technic bricks :) you could maybe make the angle a bit steeper on the front to get the perfect look, it looks a little too short over all, I think it might just be the angle on the front.

Thanks! I know some of the angles as well as proportions are a bit off, and I will try to get it as accurate as possible (I have a lot of reference material lying around). Like I mentioned, my stock of studded bricks is really limited, not to mention outdated.. couple those two facts with my limited experience building in studded, and I really don't know the techniques and styles needed to achieve my visual goals When viewed directly from the side, the entire hull of the real vehicle slopes gently upwards front-towards-back, but at this scale at least, that will be close to impossible to build nicely. That being said, I hope to in the future build this same vehicle in a larger scale with a lot more details and functions I love the suspension system! Thanks! And it works really great! As more weight is added, the strength of the suspension must maybe be higher, but that shouldn't be a problem. Twisting the rubber bands increases the stiffness for each turn, and routing larger rubber bands to act on two sets of swing arms further improves the customization ability. I'll have to see how much the final version weighs before I can make the definitive setup Share this post Link to post Share on other sites
