Much like sandwiches and body crevices, LEGO Technic gears do not like sand. Sand however, as per the aforementioned lucheon staple and your belly button, loves to get all up in there, first causing horrible noises, then a jamming drivetrain, and finally broken pieces. But not today, as this simple yet superbly engineered 6×6 trial truck can withstand not just sand, but snow, mud, and 8cm of water!

Built by Eurobricks’ keymaker there’s 6×6 drive via three Power Functions L Motors, Servo steering, all-wheel suspension, and – crucially – complete underbody protection thanks to some strategically placed curved Technic panels.

It’s such a simple solution we’re amazed it a) hasn’t been done before and b) expect it will soon be fitted to every remotely controlled off-road Lego creation, particularly as keymaker has published instructions for his creation that are available for free. We don’t normally link directly to instructions but if you release them free of charge we will!

There’s more to see of keymaker’s sand-proof truck at the Eurobricks forum, and you can take your truck trial to the beach via the link above.
