i didnt have problems with my ezrun 9t on 2s but the esc melted on 3s. im asumming that gearing the motor up so it goes as fast as 3s but with a regular 2s lipo is ok for the xerun seeing its 120amps not a mere 35. Am I correct or should i just gear it normally and put a 3s when i want to go all speedy</p>
