Not quite to the same scale as @Pete J, but started my Lego off-roader. I got all the functional components completed so about 2/3rds of the build, just bodywork left to complete. Bluetooth set-up and started a bit of driving. Took a couple of hours in total. After a bit of a play, I made 50% of the available gear ratio changes to get more climbing power (at the cost of speed).
