While assembling the latest and the biggest LEGO Technic set ever, I came up with countless versions of the introductory paragraph for this review. However, once I turned this thing on and spend some time operating it, it became clear that none of my paragraphs work better than raw facts about the set which speak for themselves. So, here is LEGO Technic 42100 Liebherr R 9800 Excavator, the biggest LEGO Technic set ever with 4,108 pieces, among which are 7 Powered Up motors and 2 smart-hub. The finished model weighs around 6 kg / 13.2 lbs (including the weight of 12 AA cells). This is a fully motorized copy that can be controlled via a smartphone or a tablet and it is all as good as it sounds. With impressive numbers comes an impressive price tag; the set is available for US $449.99 | CAN $549.99 | UK £399.99. And here comes the most important question: is the set worth the money? Let’s build it, test it and find out.
LEGO Technic is getting bigger this year, with the Liebherr R 9800 Excavator (42100) clocking in at a massive 4,108 pieces, making it officially the biggest Technic set ever. It’s now available for pre-order from LEGO.com for US $449.99 | CAN $549.99 | UK £399.99. Although the site doesn’t list its release date, we expect it to be Oct. 1 based on the previously released catalog. Using a customized version of new Control+ app that we just featured in our review of the brand new LEGO Technic 4×4 X-treme Off-Roader (42099), the giant mining excavator has not one but two smart hubs and seven motors.

Leibherr mobile cranes are like buses, two come along at once and you are not sure which to jump in. Thankfully we can admire both of YU KEE LIU‘s builds as these all-terrain mobile cranes are fantastic in both accuracy and build quality. The first build depicts the Liebherr LTM 1350 mobile crane and the model is capable of extending, lifting items and moving them on its rotating axis.
Yu Kee Liu has managed an impressive feat of engineering with his LEGO version as you can see from a view with the crane arm extended.
