This truck is very well engineered, and the build is very Lego Technic - that is, not over the top, but nicely put together with everything it needs. You can still see most of the technical functions in operation. The way you've used the gearbox is pure genius! The lights on the roof are a very nice feature and I love the simple controller you built onto the battery box. I'm a big fan of models built using older-style lego pieces and this is a very fine specimen! 5 Stars for you!
