Transmitter channel numbers? was created by sfcsoup

What are the channel numbers on a transmitter?

I thought that it did not matter if you were in MODE1 or MODE2, the right stick was channel 1 and 2 (Up/Down 1 , Left/Right 2) and the left stick was channel 3 and 4 (Up/Down 3, Left/Right 4)

On the EMU screen (does not matter if I am in MODE1 or MODE2) the keyboard keys r/f (aileron) changes the values in channel 3 which is not what I thought the channel should be in MODE2. I expected it to change channel 2.

HELP!!!!

Every radio transmit their channel data in some physical order.
We use this order to number the channels in deviation.
However these channels may have different meanings in the different protocols of the different vendors.
Walkera uses EATR (i.e. Ch1=elevator, Ch2=aileron, Ch3=throttle and Ch4=rudder) channel order, while Spektrum for example uses TAER, others use AETR.
Modes on the other side determine which stick controls the throttle, elevator, etc.

OK. I think I understand that.

However does that mean that as I change protocols in deviation my channel lineup will change, ie, TAER for DSMS, and EATR for DEVO? If so that would explain a lot why my motor runs
(prop off) when I think I am trying to change my ELE settings and other strange things.

Exactly. If you change protocols you have to change the channel sources as well.

This is the order when you open a model, defaulted to devo protocol

This is what it looks like after you change to dsmx. Notice the channel names and the channel sources...

There are 10 types of people in this world. Those that understand binary and those that don't.

On a related note, does it matter if I have all 12 channels activated in my model files?

Does that take up more transmission space/increase noise/increase tx current draw etc?

Pros and cons?
