the 5e is not a computer radio and does not have any programming. so you will not see any endpoint. NOR refers to servo direction, either normal or reverse. You can change those functions on the 5e, but that's about it.

as mentioned earlier, your problem may or may not be reversed throttle on the transmitter. Not sure where it is supposed to be for spektrum, but for some other radios the throttle channel has to be reversed for an electric ESC.

the ESC will not arm if the setting is incorrect.

You can try reversing the throttle setting. but first REMOVE the prop so that you don't get bitten.

If the ESC does not arm (beep) in either reverse or normal setting, then there is something else wrong perhaps with the ESC or the motor.

the most common problem with what you seem to be describing is a cold solder joint (bad connection) in one of the three motor connectors on the ESC or the motor.

Re: Help me with electric setup problems?

NOR usually means normal. Servo endpoint is also servo travel. I don't know how much programming the 5E has but if you can find servo travel it will show 100%. if so, go to a higher number than that. I would take the prop off when programming too, in case it goes to full throttle when you do find the method.

Re: Help me with electric setup problems?

Those are in your programming. NOR and REV are the directions you can select for each channel and simply reverses their direction of travel for the same input. Check your throttle channel direction is NORMAL. Futaba is one of the rare ones than need that set to REV.

Servo endpoints, or travel limit is also allowed for each channel and that is usually separate for each direction to set how much a servo will travel either way, (or any other device plugged into that channel). If not set high enough on the throttle channel the ESC may not interpret the throttle signal as far enough down to arm on power up.

NOTE: Most ESC's can enter programming mode themselves by seeing full UP throttle when the battery is connected. Again, they need to see a high enough signal. You need to be careful of this feature as you can inadvertently alter the programming or arm the ESC if not careful.

The fact you have no confirmation beeps on power up and that the motor will spin a bit when the throttle is moved is strange unless the ESC is moving the motor as a consequence of trying to get the beep going.

One thing that may be causing your problem is if one of the ESC/Motor connections is bad. I have often seen bad solder joints and the only way to check is to peel or cut off the heat shrink on both sides of the plugs to ensure there is a good solder bond.
