370SD brush motors replacement motors spin backwards reverse direction that have
the Walkera sticker on the motors.

These are the ones you see assembled in the pictures with a black "foamish"
background and a small screw near the gear lower left in picture.
And they have the Walkera label.

They spin backwards.
When you look at the battery connections you will see the white wire is
connected to the lead with the red dot, and vice versa for the positive red wire.

You will need to flip these wires around.
AND YOU WILL NEED TO FLIP THE DIODE TOO... if you don't flip
the diode the motor will burn out as soon as the motor gets electricity.

I cut the battery leads close to the motor, I then cleaned up the area with a soldering iron
near where the diode leads connect to the battery, exposing a little more of the diode
leads. I then cut out the diode leaving as much of the leads on the diode as possible.
Holding the diode with a third hand over the motor leads I resoldered it forming a little bridge
to the shorten diode leads with the solder. Then reattached the battery leads in the correct
position, red wire to the red dotted motor post etc etc.
When I did mine... the leads on the cut diode were long enough that I didn't really have to make
a bridge with solder for the slightly shorten leads to the motor posts.
REMEMBER YOU HAVE TO FLIP THE DIODE, just as you switched the battery leads.

If you don't flip the diode...
In addition you will probably burn out your receiver, I went through three today, one caught fire.
