Check my NB-4 Pistol too!

After a period of almost more then a year of improving, testing, etc..
He is finally is here!
Stuart, Version 4.0.
A fun little concept i got from watching some videos of walking machines on Youtube (God bless Youtube), and his first version couldn't even carry it's own weight, it had to be suspended from a rope in order to walk.
I soon found the solution to this problem, because the gears have to always make contact with each other, but they sometimes slipped, so i put a small bar to keep the pressure on the gears so they weren't physically able to slip, one problem solved. Next problem, the legs.
In the begin those were very fragile and were most likely to break under the force in which the body came down with.
This one was easy, just put on smaller legs.
Only one problem to go.
The leg supports:
They kept breaking and making him basically "break his leg", which made him really unbalanced.
Again easy.
Make the bar which kept the pressure on the gears to hold up the leg supporters..
And so, the V4.0 (4.0 already?! Wow!) was born, and finally cleared of bugs.
Thats basically this creations story and now;
I'll say some pros and no's:

Pros:
-Low part use.
-Fun to watch.
-Sturdy (survived a drop from my desk which is 3 feet high).
-Will keep your lil' bro or sis busy for hours if you need to babysit (lol).

No's:
-Hard to time the legs when building (it will look retarded with a wrong timing).
-Lots of grey and light blue spacers needed.

Lets build then!
