No show this year.

This mining version of the Unimog is remote-controlled, and features all-wheel drive and suspension. It has a bright colour scheme for high visibility and a plough to clear away minerals. Click here to see more pictures. Click here too see a very rough video.

Does anyone know the date for the Kapiti Lego show this year? I'd like to bring along some of my models, and to discuss with the organisers the possibility of a Techball tournament.

Thanks everyone. Bulle, I will think about making instructions. Zblj, I used the Casio FH100 - it's quite old now, but the only camera I've found that can record at a high framerate at a decent resolution.

Thanks David and Jurgen. The video was filmed at 120 frames per second (rather than the usual 30) so in reality the truck is four times faster than it appears in the video. As a guide, it uses the same motor, gear ratio and wheels as the .

Yes, that's fine by me. Thanks!

They also tend to rip up the surface below them to move around - take a look at the video below:

Yes, but the pipes have a circular, rather than flat cross-section, which would make 'pushing' against the snow difficult. The soft axles I've used are a bit less useless, but something like minifig spanners could only be attached at their endpoints... Exactly. Pretty much - here's a video in deep snow.

Wow, thanks everyone! Phantom59: I didn't try it on mud, so no idea. I do know that It doesn't work well on deeper snow (ie, it sinks). Larger diameter screws would help - perhaps these, or if you want to go crazy, even these, but both are so large that the thread (of the screw) would probably have to be made of multiple parts.

Basic instructions for the screwdrive are here. Built to take advantage of the once-in-lifetime snow we just had. Also entered in the Technic Challenge. It features two motors, which drive a pair of screws. It is designed to travel across soft surfaces, such as snow. It can move forward/backward, turn left/right (by varying the relative speeds of the screws), and side-to-side (by spinning the screws in the same direction).

It's in the aircraft category - Engine, Large, Center, 10 Blades

What a beast! To combat gear stress, friction etc, you might want to attach the wheels to these pieces.

I think this is what Follows Closely was talking about earlier in the thread (not mine):

Simply brilliant. Well done

Here's how to do it using either a fairly rare part or rubber bands. You can also use normal springs like below: IMG_5324 by mahjqa, on Flickr

The NZ Custom's website is down for me at the moment, but my understanding is that they waive GST and all other fees if the duty on the items + GST (as you say on the total product cost plus postage) are less than $60 - so the threshold is $400 (not $500). I've just bought a camera (which, like toys incurs no duty) off Amazon and the GST on the camera plus shipping was $52.50, and I confirmed with Customs that they'll be no charges beyond this.

The idea is to build something within 14 days of the challenge being announced, rather than just submitting an old model (complete or not).

Yup, Lego Direct.

It also features a suspiciously placed sign...

Here you go:

Thanks everyone It can't do a wheelie as most of the weight is smack bang in the middle of the chassis. I haven't planned on making a video - they take forever to make and there are many other things I'd like to build first. Although it's fairly light, it's kind of like a classic muscle car to drive - quite fast in a straight line (about 7 kph on a treadmill) but hates corners. Thank you! Your excellent review was the inspiration to build this.
