i just spoke to the guys at Tekno about that exact thing cuz i noticed the Castle motor shaft is really hard to turn with your fingers whereas the TEkno Neu is super easy. the said that there motors are newer versions the neu created because the older versions like Castles create more cogging. whether it creates more torque or not i am not sure but they smoother setup wont cog nearly as much. i imagine the next run of Castles Neu motors will be the smoother one too as it sounds like Neu has made this change on all motors they produce.

i noticed this when i tested my CAstle motor in fact. i couldnt figure out why it was cogging cuz once i had set my esc to medium start power my tekno motor never cogged. it wasnt that bad with the Castle but i couldnt run at low speeds like i could with my tekno.
