Thunder Power Z3R-8 1/8 Scale Sensored Brushless Motor (1900Kv)
Much more torque than the Tekin T8. I have always ran Tekin products but so does everyone else at my local track. I noticed a few people running the Thunder power that had a lot more rip down the straight away and just seemed to have the better edge. I did not even know Thunder power made a 8 scale motor. You will not be disappointed with the Thunder power. Also has adjustable timing in the end bell.

Thunder Power Z3R-8 1/8 Scale Sensored Brushless Motor (1900Kv)
I love this motor really: light, powerful, smooth... BUT the construction is somehow too light. After running 20-25 pack, everything seems to fall apart: timing setting is turning by itself, the screws are untightening (even though thread locking the screws), plastic part brake down. I guess it's a good motor for on road but not for offroad, when you have to jump, bump and flip over with your buggy on loose track. Waiting for a stronger version 2??

Very good and powerful motor. Smooth power delivery and 40g (measured) lighter than T8 1900. I recommend it. Top +++++
