My friend ( total noob to RC ) just bought a 1/8 ecx revenge and did not understand the main difference between 1/10 and 1/8 because when you put the two side by side the size is damn near the same. Then I got all tech-y and explained the weight, power and voltage difference. After that he made the decision himself, "oh wow I could drive right through your 1/10 axial EXO! I better be careful." I was so proud of him. Being self aware can get you very far in life.
