Well after buying my first Lego Technics model back in January (http://bonxy.info/?p=16269) I decided it was time to invest in a bigger one.
My birthday wasn’t far out so I decided to go for the Lego HGV Tow Truck (42008).
This one unlike the other was fully motorized with hydraulic T-bar and boom including winch. It also had rear stabilizer legs for picking up heavy loads.
This one was far more complex that the first one and the main gearbox to control everything was a lot more complicated and fiddly. Once the engine and the gearbox was built it went quite easy from there.
In total I think it was a 1500 piece set and took around about 5 / 6 hours to complete.
