Dropped this in my Traxxas Summit with a 20t pinion. Been running 4s (2x 2s Maxamps 6500mah 150c). I did 5 back to back speed runs with some heavy braking at the end of the runs(front flips at 100% force) and raced around a parking lot for maybe 10min. Esc was almost cool to the touch, very impressed, motor was a little warm to the touch. Confident I could run 6s, probably all day on the esc. I do recommend you get the programming card, brake force is weak at the default setting.

EXCELLENT VALUE!!
I used this combo to convert my Hyper 7 to brushless. On 4s lipo with a 16t pinion the top speed is 44mph as seen in the photo. Motor temps are around 130 deg F and esc stays very cool.
I used an Integy Hyper 8 brushless conversion kit which I had to slightly modify by drilling additional holes and enlarging the bearing carriers to get to fit the Hyper 7.
If I have problems with the motor, I'll try the slightly longer 4076 as there is plenty of room in the Hyper 7.
I've only had it for less than a week but so far, I couldnt be more pleased with the price and performance. Also, I believe shipping took around a week.
I highly recommended this combo for 1/8 scale 4x4 buggies!!
