Motor start power is basically how much energy the speed control sends to the motor from a dead stop. The higher the setting, the more power the motor tries to pull. How much energy it does pull is completely dependent on the batteries abilities. I generally recommend running this as low as necessary for your needs. If you need more power off the line, increase the setting; this can also help with certain types of cogging where the motor requires more energy to start. Our motors generally run well on medium or low. If you're happy with the power, then there's no reason to increase it. The only thing you gain is quicker take offs, and sometimes eliminating cogging. The down sides are lower run times, higher motor and battery temps, and sometimes higher ESC temps as well.

**But remember, this puts a larger strain on your battery and motor** The extra energy can only come from the battery, so the more you pull from the motor, the less run time you get and the harder you push you the battery. Setting the start power too high on an insufficient battery can damage the battery over time, or cause it to puff up more than my belly after the holidays.

As a rule of thumb, error on the side or lower timing. If you're not having troubles with the motor starting up smoothly or insufficient torque off the line, leave it on medium or even set it to low.

Hope this helps clear things up a bit, but if you have more questions, please don't hesitate to ask.
