Best Lego Technic sets: the Catamaran.

1. Lego Catamaran

The most surprising Lego Technic set.

Lego Catamaran specs:

Model number 42105
Build time Roughly 1 hour
Number of pieces 404
Number of minifigures 0

A catamaran is a boat featuring parallel hulls. They are designed to effortlessly glide through the water. Its purpose? Initially, they were invented for island dwellers to explore the sea, however, nowadays, we like to race! The catamaran Lego set is a fabulous introduction to how boats work.

This set boasts both aesthetics and function. Firstly, the catamaran Lego set actually floats on water and fits perfectly in a bathtub for racing shenanigans. Designed with an educational purpose in mind, this model features working sails. You can use the rudder to steer and raise and lower the daggerboards to maximize stability. Of course, the catamaran also looks the part. It has the classic 2-hull design, just like a real-sized version.

This set consists of about 404 pieces and measures over 32cm in length, 22cm in width, and 44cm in height. The best bit? You can rebuild this into a Race Powerboat! It might be considered a simpler build, but it remains a delight.

Best Lego Technic sets: the Material Handler.

2. Lego Material Handler

An action-packed Lego technic build.

Lego Material Handler specs:

 Model number  42144
Build time  Roughly 2.5 hours
Number of pieces  835
Number of minifigures 0

The Material Handler will certainly grab your attention. Construction toys have always been popular. As kids, we played with Tonka trucks and JCB excavators. While these toys were incredibly fun to play with, they didn’t provide a true understanding of how these machines operate. This set is made to explore how a real material handler works.

This material handler has so many functions. It has a pneumatic moveable arm with an incredible reach of around 35cm and a grapple that opens and closes. Manually, the upper arm can rotate a full 360 degrees. It even has an elevating operating cab, an undercarriage system with steering, and 4 outriggers. Oh, and it’s red!

Technic sets do often veer on the more expensive side due to their complexity, but even though it only consists of 835 pieces, this set is very much worth the money. Size wise it measures 33cm high, 40cm long, and 17cm wide. It features an intricate and highly functional design. So much so that the instruction booklet consists of a whopping 196 pages.

Best Lego Technic sets: the Monster Jam Dragon.

3. Lego Monster Jam Dragon

The cheapest Lego Technic set.

Lego Monster Jam Dragon specs:

Model number 42149
Build time Roughly 30 minutes
Number of pieces 217
Number of minifigures 0

Founded in 1992, Monster Jam is a live motorsport event that consists of three types of competition, racing, two-wheel skills, and freestyle. Monster Jam has inspired Hot Wheel toys and video games, and now Monster Jam enthusiasts can relive their favorite moments from the arena in Lego form, with the Monster Jam Dragon set.

This set is very aesthetically pleasing. Designed to resemble a dragon, this set features captivating spikes and horns – truly cool! It sports a sublime green color and includes stickers that enhance its dragon-like texture, complete with fiery flames. (The only thing that’s missing is stripes… because stripes make cars go faster right?) Its design is very authentic – we’d probably have put it in the best Lego dragon sets list if we didn’t think it would make people mad.

In terms of functionality, this set has a pull-back feature so that you can race. It is a 2 in 1 set meaning that it can be reconstructed into a Crocodile Buggy model too. While it may not be the most intricate build, its instructions still manage to span 68 pages.

The best movie tie-in.

Robert Pattinson’s The Batman was a box office hit. So much so, that a whole host of merchandise came along with it including this fabulous Batmobile. What distinguishes this model from previous Batmobiles is its inclusion in the Technic range, offering numerous functional features.

This model faithfully captures its onscreen appearance and is enhanced by two light bricks that cast a striking red glow onto the engine. It is also equipped with a yellow brick that illuminates the front grille. It has a 9-cylinder engine with moving pistons and a spinning flame, front steering, differential on rear wheels, and opening doors and boot.

Comprising a total of 1360 pieces, this set falls into the category of relatively large sets (though it’s nothing compared to the biggest Lego sets ever made). The finished model measures approximately 11 cm in height, 45 cm in length, and 17 cm in width, making it an exceptional display piece. Without a doubt, this set deserves a place on the shelves of Batman fans.

Liebherr cranes are renowned for both their reliability and power and the Lego version is no different. This set is not only massive but also incredibly impressive. In fact, it ranks among the largest sets in the Technic range, boasting a whopping 2883 pieces. This iconic crane not only captures authenticity in its appearance but also in its movement. Its design is very intricate.

Designed with adults in mind, this set presents a complex build that promises both a satisfying challenge and an engaging project. This set can be enhanced with the free CONTROL+ app. As its name suggests this app allows you to control certain aspects of the Lego set remotely. Functions include tank steering, rotating turntable, luffing jib and winch.
Notably, it’s equipped with 0.9kg of weight elements to effectively counterbalance the crane. Furthermore, it incorporates load sensing through the CONTROL+ app, providing notifications if it exceeds its weight capacity

With measurements surpassing 100cm in height, 110cm in length, and 28cm in width, it offers a fantastic display item. It features 2 smart hubs and 6 large motors to power the articulated functions. Given its massive scale, this set does require 12 AA batteries. This set is £579.99 and is readily available from the Lego website. Its grandeur certainly makes it worth the money.

The Lego Mars Rover features 360-degree steering and a movable arm. It has a fully articulated suspension, perfect for driving across uneven surfaces.
