So often Technic’s B-Model, road graders like this Volvo G990 are the vehicles that give almost everything else we post a place to exist in the first place. So here to shine a light on their significance is Eric Trax, and this brilliant, er… 42114 B-Model…

OK, a B-Model this Volvo G990 may be, but it doesn’t feel compromised for it. Utilising around 90% of the parts from the 42114 6×6 Volvo Articulated Hauler set, Eric’s alternate redeploys the Control+ motors, control unit and app to give his grader remote control drive, steering, a three-speed automatic gearbox, and to power the main blade’s elevation.

The model features a few mechanical functions too, including a working piston engine, manually controlled ripper, and a seven-position blade angle. Best of all, Eric has released instructions for his road grader so you can build it for yourself if you own the 42114 set, and there’s more of Eric’s Volvo G990 B-Model to see on both Flickr and at the Eurobricks forum.
