(from an original post I did on Rctech)
I did dismount my T4 gearbox for some cleaning (to much grinding in that differential :P).
I did that for my Tekin motor as well.
I must admit, I'm impressed by the overall qualtiy of the internal build. Except of two copper strand that were misplaced and a slight bending on rotor side, most other sensorless motor on the market are way cheaper in term of construction.
