Propellers are powered and when you playing with this plane you can turn on propellers you need just six elements to power up them.
There are 512 bricks.
I got this idea when i was just 4 years old,but now i just improved my idea and then i discovered Lego digital designer then i started to building first robots,planes,engines,forts,mini-figure controlling suits,and etc.
I was thinking where i can share my all of ideas,then i saw lego cuusoo on youtube and then i get here and publishing my ideas.
To make this site is very good decision i think.Because you can create and publish your dream ideas and even if someone likes you can get 1% of those moneys.
