Power Blockz engineering building block kits are for adults who care about how things work as much as how they look. The collection brings together more than 250 technical brick kits: working engines, cranes and excavators, battleships, locomotives, rockets and aircraft. Designs come from Mould King, Reobrix, Sembo, Gobricks, Xingbao, 12GO and CaDa, and every set uses ABS bricks compatible with the major building brick systems.
Many of these technical building sets are motorised or remote controlled. Build the W16 Engine & Transmission from Mould King and watch the pistons cycle, or put the RC Articulated Dump Truck and Heavy-Duty RC Excavator to work on the floor. Explore dedicated engine building kits and heavy machinery building blocks, from the Claas Dominator 370 Harvester to the RC Logging Truck.
Scales run from compact 1:300 warships to 1:8 flagships and 1:1 display pieces. Prefer to sail or fly? Browse ship building kits and space building sets, or filter every remote control building kit in one place. Kits arrive with numbered bags and illustrated instructions, and every order ships free worldwide.
Six collections, each built around one branch of engineering, from powertrains to rail.
Motorised V8, V12 and W16 engine models with moving pistons and working gearboxes. Highlights include the W16 Engine & Transmission and Scania Truck Engine & Transmission from Mould King, the Twin-Turbo V12 Hypercar Powertrain from Eikee and the Naturally Aspired V12 Engine from Reobrix.
Shop 74 kits →Cranes, excavators, dump trucks and farm machines, mostly at 1:8 to 1:14 scale. Build the Heavy-Duty RC Excavator or RC Logging Truck from Mould King, the Telescopic Arm Forklift from Reobrix or the Claas Dominator 370 Harvester from CaDa, many with remote control.
Shop 115 kits →Battleships, submarines, pirate ships and sailing yachts. Choose the USS Missouri BB-63 Battleship from 12GO, the German Battleship Bismarck from Gobricks, the Queen Annes Revenge from JMBricklayer or the Zhegao Cruise Liner, from easy 2–5 hour builds to 18h+ expert projects.
Shop 75 kits →Rockets, satellites, rovers and starships for the display shelf. Gobricks leads with the Falcon Heavy Rocket, Hubble Space Telescope and Pioneer 10 & 11 Spacecraft, alongside the Tianhe Core Module from Sembo and the Mars Explorer Rover from Mould King.
Shop 74 kits →Airliners, warbirds, jets and helicopters from 1:8 to 1:100 scale. Build the Boeing 747-100 from Gobricks, the Concorde, the Sr71 Blackbird Tactical Aircraft from Reobrix or the Apache Combat Helicopter from Guly, with easy 2–5 hour kits for a first flight.
Shop 81 kits →Steam, diesel and electric locomotives, many motorised. Look for the Orient Express Original and Union Pacific Big Boi Steam Train from Jiestar, the EMD F7 Locomotive from Mould King and the Vectron Electric Locomotive from Reobrix, mostly at 1:45 to 1:50 scale.
Shop 23 kits →Two cross-theme collections for builders who want motion and scale, plus our guide to choosing a kit.
Every motorised build in one place: remote control building kits such as RC cranes, excavators, trucks and locomotives with app or handset control, from Mould King, Reobrix and Jiestar, all with numbered bags and illustrated instructions.
Tanks, fighter aircraft, warships and submarines engineered in bricks, from 1:14 scale armor by Quanguan and GaoMiSi to 1:300 battleships by 12GO. Detailed display models for history enthusiasts and scale collectors alike.

Many are. Motorised engine kits such as the W16 Engine & Transmission come with a motor that drives the pistons, and machines like the RC Articulated Dump Truck, Heavy-Duty RC Excavator and RC Crawler Crane from Mould King use remote control. Look for the “remote controlled” tag on each product, or browse the RC building kits collection.
Start with an easy 2–5 hour kit that still has working mechanics. The Motorized Flat-6 Boxer Engine from Mould King, the Large Excavator Model from Sembo and the Mobile Crane Truck Model from Xingbao are all rated easy and teach gears, axles and linkages before you move on to 18h+ projects.
Scale depends on the subject. Heavy machinery and engines mostly sit at 1:8 to 1:14, locomotives at 1:45 to 1:50, and warships range from 1:300 for the USS Missouri BB-63 up to 1:100 for the USS Iowa Battleship. Some display pieces, like the Zhegao Cruise Liner, are tagged 1:1.
Mould King designs the largest share, especially cranes, trucks and engines. You will also find Reobrix, Sembo, Gobricks, Xingbao, 12GO, CaDa, Jiestar and Zhegao. Each maker has its own style: Gobricks leans towards scale realism, while Mould King focuses on motorised function. Use the maker filter above the grid to compare their builds.
Expert kits carry an 18h+ build-time tag. The German Battleship Bismarck by Gobricks, the RC Logging Truck and the Claas Dominator 370 Harvester from CaDa are typical examples, best spread over several evenings. Intermediate kits such as the A-Class Naval Destroyer take 5–10 hours. Check gear alignment carefully before closing each section.
Check the numbered bag for that step first, since small technical parts often sit in the next bag. If a piece is really missing, request it through our free brick replacement service. Every order also ships free worldwide and is covered by a 30-day return guarantee.
