Okay, which step should be first? Of course buying some Lego... and after hundreds watched lego sets reviews I picked this one, second in a row biggest set:
Hmm, it’s not so familiar with tank, but this set have much more common with final idea then others. You can find full info by it’s identifier number (42009). And full list of pieces is here. Mostly important that I have now few big and small linear actuators as well as toothed bars, motor and about 2600 other peaces to make a mechanical skeleton of the tank.
Hope it is the last lego set I bought - all other pieces as well as motors and remotes will be ordered separately. $250 are gone forever from mu budget. Sad but true, but we still have $250 left :)
And of course I definitely had fun with assembling it :) ...after 3 days:
Here is some photo from my evening workshop, but here you can find much more interesting assembling video and review.
