Well, tested the Ezrun 9T yesterday...
It goes like a charm, like you would expect from a 4300kv motor.
It feels like it is just a little less then the mamba 4600, which is exactly right!
The only downside (for me) is that is was not plug, press set, throttle front, set,.. I really should read the manual better, but i got it running
The motor itself seems like it is fairly small because the cooling ribs are almost 2mm thick.
The ESC fits exactly in my df-03 where room is not for spare.
It really is a lot for less!!
