Hi Jennifer

It was definitely worth to wait for your newest marvel! It’s wheter a CAT nor a Liebherr - finally a model that is truly different from what we’ve seen so far ;-)

When I saw the first pictures, I thought 1x6 tiles on the crawlers would look great. But then I downloaded the action videos and had to realize that the tiles would fall off quickly in such heavy duty applications.

It is most impressing to see your model move and dig (I would never dare to use my creations in such harsh environments) - congratulations!

Although your site is - once again - very easy to follow and the pictures show lots of details, there is something I couldn’t find out yet. It concerns the track rollers. How have you built them to realize a smooth ride? Did you use the 16 tooth clutch gears like TJ has in his R996?

Just an idea for the case you should looking for your next challenge: what about implementing drive, steering and a (remote) control to the 8455 backhoe loader? You still could make it look like a JCB or a Case :-)

Greetings from Switzerland
