Tekin Redline brushless motor

[Mister-T]

Still working flawless, I run around 70° celsius with 23/87 gearing.
Hacker E40 are made in china stuff.
I can't say about hacker or GM, but on thing is sure. There are not based on the same design. If you plan to run with a sensorless ESC (VXL/ Mamba max/ Losi entry level ESC / Tekin R1) , A tekin motor is ano brainer. They worth every bang for buck.

I know that TC/On road is very hard on sensorless setup because off large gearing they do use. But on off-road the drive feeling of this motor is good.
