ezrun 9t

[gerbil]

hi i ve recently aquired a ezrun 9t and speedo combo
on the motor can it says 9t/4300kv,now i was thinking this is the same as a 9t brushed motor? or am i completly off there,also what motor would it be if it was a brushless motor (6.5) thats what i was thinkin?
next is ive tried it on the bench with my normal gear and it doesnt seem any were near as fast/noisey if that makes sense
i ve tried setting it up with the program card and as far as im aware its on full power
so really my question is does any one run one of these systems and had any probs or do they run quietly any way any help much appreciated
