how to mount connectors on motor.
okay, I know this is probably a really stupid question, but I have the gold bullet type connectors and was wondering whether I put the male or female ends on the motor side. I know it probably makes no difference but I would like to do it the way that most people do it.

Put the male on the motor and the female on the esc. Then you wont short the esc if you should happen to connect it to a battery without motor.

What comes around goes around.

Hello

Please elaborate. Why would you not want to shorten the wires?

Regards

On many motors, the wires that come out of the casing are the ends of the actual motor windings. They are painted with an enamal-like paint to prevent short circuits in the windings. The ends are cleaned and tinned so you can solder to them. If you cut them short, you cannot solder to them unless you clean the paint off. The paint that burns off with the heat of a soldering iron is not used in motors.
Some motors have the windings terminated inside the casing and ordinary stranded wire is used to extend them outside. These can be shortened and resoldered. The way to tell which you have is by the nature of the wire. If it's flexible, stranded wire, it's probably OK to shorten it. If it's solid core, probably only two cores twisted together, and it feels stiff don't cut it. It probably won't be very long anyway.
Keeping your wires as short as possible is good, both for maximum power, but also to reduce radio interference. For micro helis, it's also a possible way to lose weight. Copper isn't very light.

solder
Question on soldering....

Since the wires coming from the motor are already tinned, do I need additional solder to connect to bullet connector?

Also it seems that the bullet connector "housing" is much larger than the wire coming from the motor..I assume I should just solder to one side of the connector?

If anybody has pictures of the soldering process please provide link....I don't know why the instructions to the motor/esc don't include a simple diagram...

Thanks!

you still want to use a little solder. Add some solder to the wire ends. The gold connectors I had had an indent for the wire to go into, although shorter than I like. Just put some solder on the wire. Heat up the solder real good, shove the connector on and let the solder cool and it should be fine. You need a decent soldering iron. I usually set mine to around 700 degrees. Don't forget to turn it off like I did, I had mine on for 24 hours, I'm lucky I still have a house.

robl45,

Thanks....that's exactly what I did....I thought the hole where the wire goes was a little small also...that's what prompted my question...

Looks good now with everything shrink wrapped....
