I'v been continuing to work on my MOC trucks since my last update. Made a fair bit of progress. I'v finished revision 4 of the massive tipper truck. I'v run it through LDD manager and fixed any problems there, so it's all ready to go. Just need to get the money for it now. I spent a lot of time putting motors in it trying to get it to drive. Last night I did a real world test to see how much weight 1 XL PF motor could move, didn't even move 2KG. I could fit 5 XL PF motors in the truck, which is no where near a enough from my testing. So I had to give up on that plan. Specifications: Length: 108cm (just truck) - 217cm (with trailer) Width: 35cm Height: 42cm (at tallest point) - 30cm (rough average height) Pieces: 12,798 - about 7,800 for just the truck I'v also made another difference truck, still needs work though.

Thanks, I was hoping to get away with only 1 Medium PF motor for the tipper. But I'm not too concerned, i'll use whatever works. I will figure out the tipping part when I build it as its too hard in LDD. It can't handle rotating such a large amount of pieces. Does anyone know if those numbers the calculator gave me should move the truck? Or will I need to change the gears to get more torque etc? I know I have calculated this stuff back in High School, but its been a few years now and I can't remember.

Thanks for all the help guys, you've been very helpful. I am current designing a large project here, and I have decided to motorize it. http://www.eurobricks.com/forum/index.php?showtopic=66885 I have 5 XL PF motors driving it, one for each wheel line on the truck (not geared down or up, 1:1 ratio). Two M PF motors, one for steering (geared down, mainly so it moves/steers slow enough) and the other for lifting up the tipping part. The calculator came out with. Uploaded with ImageShack.us

I'v got a few questions about the new motors and such. I'v got a fair bit of experience with the older style ones, but not with the new ones. 1. How many of the 58121 (big motor) can I connect to one battery box? 2. Approx. how much weight can one of those motors move? Thanks for the help.

I posted it here earlier. http://www.eurobricks.com/forum/index.php?showtopic=66885

Thanks for the tip about connected bricks tool, just checked and its all good. The only things that came up are some parts of the steering system I couldn't fully connect in LDD but would in real life. Good idea about moving the front wheels forwards, I'll do that. As for the width, there is no way I could make it less without rebuilding about 75% of it. I do see what you mean about the hood being a bit wide/fat looking, I'll make it a bit thinner. The wheels do look a little on the small side, I think some of it is just illusion as I did a quick ratio measurement with my 5571 Black Cat + plus looking at trucks on google images. However its getting late here, so i'll worry about it later tomorrow. Once I start building it will post up a blog/build log on here. I have plenty of progress photos in CAD, this is currently version 3.

Thanks I just ran it through LDD Manager, thank you so much for pointing me towards that program. It auto generates a parts list, that just saved me so many hours work and made my day. As for checking the parts can be brought in real life, there were a few small problems with colours, however nothing I can't/haven't fixed.

Thank you for the feed back. I agree the wheel may be a little on the small side, but as you said they are the biggest I can get. I will investigate it more, I'll get some pictures of real similar trucks and workout a ratio and see how that compares to my model. If it is out enough i'll do a re-design. I hadn't heard of LDD manager until now, so i'm looking into it, however I only used red, black, new grey, new dark grey and blue bricks + lights. The trailer connect would pivot, how well is a bit hard to tell on LDD. As when the model starts getting big the rotate tools doesn't really work. I could easy change it as I build it though. Thank you

I would like some opinions on areas to improve on my latest project I have made in CAD. I want it to be perfect before I build it in real life. It is a massive version of the Lego 5571 Black Cat truck. Don't worry to much about the trailer right now, as it is stage 2 and not going to be built any time soon - unless I win the lotto. Specifications: Length: 108cm (just truck) - 217cm (with trailer) Width: 35cm Height: 42cm (at tallest point) - 30cm (rough average height) Pieces: 12,551 - about 7,800 for just the truck You can fine more pictures on my brickshelf page... http://www.brickshelf.com/cgi-bin/gallery.cgi?f=497926 Image Thank you

Hi, I just signed up here and thought I might introduce myself. I'v been collecting and building Lego since I was 3 years old, i'm now 19. My collection has about 70,000 pieces (including spares/random pieces). That's not just a guess, all my main sets added together equal 66,651 and I have a fair few others + spares. In recent times i'v been getting more into designing my own creations. I'll be posting up pictures soon of my latest work in CAD, so I can get ideas on how to improve it before I build it in real life. It's quite a large project.
