OK.. first up.
Aux 4 and 5 are in fact 1024 resolution, they're just sampled at 1/2 the rate of the other channels. This is why we don't recommend you use them for primary flight controls such as aileron, elevator, or rudder.
Doug, can you elaborate? What does this exactly mean, sampled at 1/2 the rate?
TIA

That means that the other 8 channels are updated from the TX to the RX in every single "frame" that is transmitted, whereas the Aux 4 and Aux5 are updated every second frame. (A frame is just a collection of information that is sent out by the TX at discrete intervals, and includes both information on required servo positions and data used for failsafe purposes).
If you were to put the split elevators on a Bobcat on channels Elev & Aux 4, and you gradually fed up-elevator input in, one of the elevators would move up every single time a frame was sent, whereas the other would update every 2nd frame; that would make one elevator half seem very smooth, while the other seemed a little "jerky" (though, depending on the setup, the minor discrepancy could be very hard to see). That's why JR says it's better to use these channels for something other than primary controls. I use Aux 4 and 5 for things like speedbrake and wheelbrakes - there's more than adequate response for controls like that.
