Hi Is it Vital the motoers are connected when setting up one of these Esc's my thinking (probably wrong as ususal) is that you are only kind of tuning your esc to your Tx and seems odd to slam the motor on full fore and aft if not neede to
Not that I've ever soiled my hands on such wares but I would think that the only reason why you would connect up a motor would be if you wanted to set something less than its own full speed to be your model's maximum speed when the throttle stick was fully forward or back. If you don't connect a motor then be VERY sure that the two connectors which go to where the motor would otherwise be are nowhere near each other while there is power on. That said, it's nice to be able to see the motor responding to the stick while you press the button and watch the lights flashing.
I don't think it is essential that the motors are connected when you set up the ESC but it doesn't do any harm if they are. You don't actually need to slam to full throttle, just move the transmitter stick progressively to the max limit. It is also reassuring to be able to see that the propeller is rotating in the right direction for forward and reverse.
Having a motor connected or not doesn't matter. What is important is that when learning, the ESC gets its information in the right order. With most transmitters, this means that the servo direction switch is set to N. Unless you have a Futaba with the logic reversed.
Suck it and see, but try to understand what the magic boxes are doing.
Thanks Malcolm thats exactly what I am trying to do by not blindly accepting that this or that is required without asking the question. I did only ask if it was needed to have the motors connected as in my case the initial setup was easier ( for my peace of mind)without
