Lets see... Who specializes in designing brushless systems and who requests a brushless system to be made from a company overseas? Tekin and Castle design and destribute there stuff, while the Losi does not design their stuff. I've never tried a tekin esc, but i have both tekin and castle motors. It's quite apparent that tekin put in a lot more effort to design the motors than castle. The tekin has solder tabs and the stator seems to have been been engineered for the least amount of cog torque (very easy to spin by hand). The castle is basically a copy of the neu motors with a few changes to make them more suitable for cars. Both are great motors, nonetheless. My tekin is a 1900 kv 1.5Y and my castle is a 2650 1Y so it's hard to compare temps. The tekin definatly runs a good 20-35 degrees cooler even when geared for 50 mph on 5s.
