[RUSTED]

6s would be too much power for me , i dont have an esc that handles 6s and i dont want to replace diffs each time or have to buy the hybrid bulks and1/8 diffs , right now im using a 10 l on 3s its goes about 30mph but i need like 5 - 10 mph more , right now im tryn to make the e maxx more raceable and bought alot of parts including a new transmitter heres the link http://www.rcuniverse.com/forum/m_7993686/tm.htm so i dont the the money to buy a new motor so ill be running the 10 l for now , but will a single or twin vxl be better???
