In this video Tom walks our fellow RC enthusiasts thru the different Auxiliary Channel modes on the Spektrum DX3 Smart and how to use them. This is a great video for those with crawlers that include the DX3, like the Axial SCX10 iii, Or those looking for a extremely capable, yet affordable, 3 Channel transmitter for there crawlers, scalers and bashers.
In this video we cover how to setup a 2 position momentary switch which is great for setting up the Dig servo in your crawlers and scalers. Here is a shortcut to that section – 1:40
Then we cover setting up a 3 position momentary switch, which is great for winches. Here is a shortcut to that section – 5:48
And Finally we go over setup of the 5 Position Latching mode. This mode is likely the most versatile because it can be used for a 2-5 locking positions, 2 being perfect for ON/OFF functions like lights with controllers and locking functions like 2 speed transmissions. Here is a shortcut to that segment – 8:00
One thing we want to stress is that you make sure to rebind your receiver after doing this type of programming. This is so that if the rx goes into failsafe, that it does not force the servo into a position where it is binding up and damaging the servo. Also note that failsafe positions are the position that the receiver will go to when you power on the receiver without the transmitter being on first 🙂
