Have tried the 5.5t, 7.5t and 8.5t. (silvercans)
Every motor has worked great and runs very cool 55-65c.
Currently running the 7.5 in a xb4 and t runs smooth and has plenty of power, runtime 20min+ with the turnigy 5600mha aspec
The 8.5 is in a dex 210 and that to works great too...
I use a hobbywing 120a esc in both cars....

Great motors for a very low price
