Hello,
I received my Tekin motor.
Overall aspect and packaging is great, it made the motor looks like high end product :P, packaging say
Designed in USA made in China.
Come with everything, including inox (!) mount screw, spring connector (the good one, not the banana) 11 ga wire and a bunch of stickers :), and the motor
by the feeling it's slotless design maybe with a iron ring (can still feel a very very ligh resistance in the rotor at some position).
I used it yesterday, feel strong and smooth power band with my mamba max, run great even with bad battery. Very silent as well.
Summary, for 75 $ we have here a good alternative to Castle creation motor, with a larger choice of KV and lot of stuff inside the box.
PS: I still want Mamba max stickers :|
