Most sensored brushless motors don't seem to come with wires attached. I had to learn to solder a brushless motor. I figure I'll post a "how to" for people like me.
60 watt or hotter irons work better. 30w-40w will make you doubt your skills. It's not your skills. They just get cooled too much every time you solder.
I used 14 gauge wires ($1.50 for 1m each). If you want to go smaller turn than 10.5t, thicker 12 gauge would be better. (Tamiya ESC's wires are 16 gauge, so... but TBLE-02S isn't suitable for anything faster than 10.5t, so 14 AWG is fine in this case)
10 pairs of 4mm connectors were $3.60. Enough plugs for 3 motors.
Pure tin, some silver & flux is stronger than stuff with lead. (lead is weak and toxic anyway)
[ I cut the wires to about 3 inch and a 1/4 (about 8cm). But the length is up to you ]
[ Tinning will make it easy for the wires to stick into the plugs. The gator clip wouldn't hold all 3 at the same time. ]
[ This shows two gator clips holding both ends, but I held the wire and slightly pushed it in as it melted. ]
[ I only had black and red heat-shrink tubes ]
[ A plier can be a nice cradle for the motor, so it won't roll around ]
[ "A" turned out to be a bit more voluptuous than B and C, but that's fine ]
[ Tip tinner is very convenient. Just stick it in while it's hot. If you don't tin the tip, it will oxidize and become blunt after a few times ]
[ A Tamiya Club member let me know the colors. A,B,C contacts are Blue, Yellow, and Orange. "Bring Your Own" Booze is missing! ]
These 4mm connectors get plugged to Tamiya TBLE-02S ESCs just fine -- even though these are not the traditional "bullet connectors." You will still need a sensor wire. Trackstar motors come with a sensor wire.
