Strength in Numbers

Lego RC Pick-Up Truck

As any builder of remote control Technic creations will know, LEGO drivetrain components – especially u-joints, axle connections and gears – are often not up to the job of delivering the torque from LEGO’s excellent Power Functions motors to where it needs to go.

Gears shearing in half and u-joints snapping are problems that regularly occur, particularly if third-party battery and software products such as SBrick or BuWizz have been used to increase power far beyond what LEGO envisaged. We’ve even experienced this here at TLCB Towers, as an ‘accidental’ collision between an RC creation and a TLCB Elf can push a part past its breaking-point.

However Eurobricks’ Kevin Moo has designed a cunning solution to the problem, with his Toyota Tundra-esque 4×4 pick-up truck utilising two driveshafts for each of the live-axle suspended differentials.

Power is sent down both sets of components, effectively halving the load on each gear, u-joint and axle connection, and therefore the likelihood of a part failure. It’s an ingenious yet simple solution and one that enables Lego models to take more power, more reliably – watch truck trial builders use this design and then double the number of motors to end up right back where they started!

Kevin’s dual-driveshaft pick-up is also a thoroughly excellent model in addition to its clever driveline. Power to all four wheels comes from a single XL Motor with a Servo for steering, there’s superb live-axle suspension front and rear, opening doors, hood, tailgate and load cover, LED lights, and a realistically detailed body too.

There’s much more to see of Kevin’s brilliant build on Eurobricks via the link above, and you watch how the dual-driveshafts work via the top-quality video below. Take a look whilst we see whether breaking parts in ‘accidental’ collisions with TLCB Elves is a thing of the past (it’s all for science).

Technic Tacoma

[Elven Screaming]… [Thump!]… [Elven Screaming]…

Sigh. It’s been a while since we’ve had a mass Elf squashing here in the office, but today, thanks to builder Madoca 1977, we were reminded what it feels like to slide a spatular underneath a flattened mythical creature to prise it out of the carpet. Still, in this situation it’s considerably better than being an Elf.

The cause of the carnage was this, Madoca’s (brilliant) Technic Toyota Tacoma pick-up. With remote control drive and steering, plus a two speed gearbox, it’s a model that is marginally faster than some of our fatter Elves. That’s Darwinism in action right there kids.

The aforementioned Elves would have caused a traction issue for most remote control models once they became smushed underneath the wheels, but Madoca’s Technic Tacoma not only features four-wheel-drive and front and rear suspension, but locking differentials too, meaning that even with three wheels lifted off the ground the fourth will continue to drive the truck forward.

With the model now safely under our control and the jubilant Elven discoverer contentedly cashing in its meal-token, we have an exciting half an hour ahead of us tidying up, so whilst we get on with that you can check out all of the images of Madoca’s superb Toyota pick-up at the Eurobricks discussion forum, where there’s also a video of the truck in action.
