Tekin RS Gen3 SPEC Sensored Brushless ESC/Gen4 Spec R Motor Combo (21.5T)
I thought I was saving money buying other brand ESC, the features and capability for this 'SPEC' ESC are worth the price, it is smaller and lighter than most, it has more features that don't require hotwire my only issue was the increased difficulty of soldering the posts, they don't tin easy and the capacitor was also a bit challenging, but once together has worked flawless. The motor is similar to any high end motor with quality magnets, I was not lacking speed or punch. I installed in my M08 and ESC fits so much better due to small size. Having a real switch helps also.

Tekin RS Gen3 SPEC Sensored Brushless ESC/Gen4 Spec R Motor Combo (21.5T)
Tekin does not make a 25.5T motor combo with the RS Gen3 Spec ESC.

The part number TEKTT2791 is for a 21.5 turn motor.
