| Motor direction
Does a motor have a prefrence of which way it turns? As in; When it is wound does it then take a prefrence to which way it would get more performance? |

The answer depends on the timing of the motor. A motor timed at 0 deg should perform equally in both directions. A motor with advanced timing will perform better in the forward direction relative to said advance. When you buy machine wound motors they are generally set at 0 deg timing so that there arent any problems with putting it into different models that may need it to spin opposite directions. When you buy nice hand wound motors you can specify what you are putting it in and they can time it for you. Also helpful on an MOA because they will time one one direction and the other one the opposite direction for your front and rear motor. |

Sense. If you buy a motor that will allow its endbell to be moved, you can change the timing yourself, therefore, the answer to the question if they have a preference, is no. |

What is the best way to adjust a motor to zero timing, since we are speaking of such.

loosen (not completely take out... just loosen) the two endbell screws and the endbell should turn. There should be a zero mark on the can and you simply line up the timing line on the endbell with the zero mark on the can.

I understand that, but is that the only way? Can you test motor w a volt meter or something similar? I have had one or two that seemed off with this method. Like more spark off brushes in reverse, like it had some adv timing.

In general, when looking at the brush end of the motor, the line through both brushes is 90* to the gap in the magnets (assuming 2 magnets) if you can't see a timing mark. Advanced timing depends on which way the motor turns for forward (which is different for a front motor vs. a rear motor on a MOA). Arcing could be short brushes, weak brush springs, dirty/burned comm, chipped brush edges, hanging brushes, etc....... | |

You can "reverse" a motor by turning the endbell 180*...or...swapping the 2 motor leads. Advancing the timing is twisting the endbell against the direction of "forward" rotation. |
