Hi All,
The iconic ARGO 6x6 XTV (extreme terrain vehicle), made by ARGO Industries in Canada, was my inspiration for this project; a remote controlled Technic Power Functions version of the real life machine. The ARGO is a formidable little amphibious all-terrain vehicle that will take you deep into the wilderness and get you back safe and sound.

This model uses disk brakes to lock the left or right wheel-sets to skid-steer. The wheels are connected with chains like the real ARGO. The handlebars are connected to the disk brakes using flex cables. The handlebar assembly decouples the left and right brakes, so when you twist the bars only one side is activated. The brake assembly is very compact. When you want to control the ARGO remotely, you can drop in the handlebar servo assembly.
Here's a video of the ARGO that shows the different functions. If you like it, please check the ARGO out on ideas.lego.com. Thanks!
