Now I have got my Dark Impact

. I can just say that Wow! This buggy is cool! I love it! Here are 2 pics of it. I haven't painted the body yet thought...And the pics are taken with a cellphone so the qualit isn't any good...
Now I need to know a good motor for this buggy. Brushed and Not under 11 turns. The Nosram Vision 14x2 motor doesn't have enough power to impress me...So any ideas of a new motor?
