>>1454500>Any tips on how to start?If you just want to build them and not get into the weeds with customization and painting it's pretty easy.
To start with you just need a pair of hobby nippers and maybe a glass file (to file down the nubs after clipping a plastic part off of the runner). Try some "HG" kits as they're the standard and relatively simple to build, you can just follow the instructions. after that you could also try "Real Grade" (same size as HG but more detail and higher part count) and "Master Grade" (bigger with a lot more parts) kits if there are robutts you like in those lines.
dalong.net has a good gallery, you can just look through all the model kits and see which ones you think look cool
