The Timing is the pulse or signal sent by the ESC to the motor. Its basically a “on / off” signal. The ESC sends the opposite polarity to the motor at the exact time as the magnet passes the bell. This causes the 2 magnet and the bell to repel and is what causes the motor to spin.
For most speed junkies, we want the timing as high as possible so the motor is spinning as fast as possible. The one problem with Super High timing, is that the pulse signal is sent too soon which actually will put the motor in “reverse”. The most common side effect is that awful screeching you hear. THIS IS BAD
So the most scientific way to set your timing is to keep advancing until it starts to screech, then decrease by one setting.
Do you need to advance the timing…in most cases NO.
Could you achieve a ‘faster’ motor while increasing the timing..Possible
Is it best to leave it in auto. Beginners YES, guys with experience and play around with this setting
FYI. This works with all motors not just parkjets, and actually, the larger 40 size motors, we have to decrease the timing since the larger motors spin much slower then then the parkJets
Hope this helps
