Default soldering a motor

I have to flip the wires on my stock Novak motor for my dex210. The soldering iron I have supposedly heats to 950 degrees bit it won't melt existing solder. How hot does it have to be?

Flux your tip or add more new solder to your tip

Scrap the crude off the tip of the iron with an exacto or wire brush.
Re-season the tip with fresh solder. May need to wipe on a wet sponge a couple of times. You want a nice shiny tip on the iron. Also it the tip is like a pencil it's too small, you need a screwdriver tip for motor tabs.

to get the old solder off act like you are soldering the wires on, adding solder to get the old stuff to flow. it the motor is out, rap it on the bench to flick the excess off the tabs once the wires are off. Solder wick can also be used.

Don't flip the wires to reverse a sensored motor, you will damage it. A to a b to b and c to c. If the motor runs the wrong way you need to reverse it in the esc not by switching 2 wires like you would on a sensorless motor.

With some systems it's the only thing you can do... Even if its sensored..

Guys, I think he just means how they are dressed, towards the motor instead of out away from the motor. Not reverse the polarity.

Thanks guys I will try that. Its a brand new iron so there isn't any crud on it. C&B you are right the wires are running out toward the shaft. With them that way the motor doesn't fit. The wires hit the motor guard.

Ok just making sure. It can take 30 sec of heat to get the tabs to re flow. Novak uses silver bearing solder with a higher melt point. What I do on them is use some lockable twezers and use them as a heat sink just below the tab so the stator doesn't heat up as much.

As said use a little solder to help the heat move faster and use a chisel tip since it holds more heat then the pin tips do.
