Vere nice gear box. Should get CG low.

I have not seen the other Crawlers my self. I am still in the building stage.
Just built this one from information I obtained from this sight and others like it.
I can tell you that after watching the online video, mine will be able to hold its own.
I will be taking it apart and rebuilding it cleaner. Better servos, clean and paint the frame.
When I get the links adjusted the way I want them I will use them as patterns to cut solid ones.
Watch the videos and look at the other rigs on this sight, they will give you plenty of ideas.
There is no reason you can't build a crawler that is just as good or better than the store bought ones.
Be sides you don't thing these guys leave them stock do they. You just make yours better from scratch.
Besides it's fun.
