So relative to the Zoom Control Mode, it seems I can send as an example 1pulse to advance the zoom one step, 2 pulses to retract the zoom 1 step, 3 pulses to shoot, 4 pulse to fully retract the zoom, etc.

I guess the issue is if I'm able to send these different pulse strings from my RC radio?

Alternatively would be to use a script?  I noticed Gentles does not offer a 2-channel RC connector for the Canon with video out so I sent them an email to see if this was something they could do.

I do have a pretty complex RC radio (Turnigy 9XR) that does allow channel mixes and I'm assuming I could program the desired pulse strings into my radio?

I have spent the last few days reading the CHDK user manual and notice using the USB Remote, specifically the Zoom Control Mode that it appears I can do what I want without using a script and a single RC channel by sending various pulse strings to CHDK, what am I missing?
If that's all you want to do then you are not missing anything.

Yes.

Are you asking a question here?

Was thinking this was probably the wrong place to ask, but do you think the typical RC radio would be able to support sending different pulse strings on the same channel?

According to this : http://en.wikipedia.org/wiki/Servo_control the signal from a typical RC radio will be at the 50% position when the pulses are 1.5 mSec long.   Standard CHDK USB input needs pulses greater than 10 mSec.  Using the high speed timer option, you can probably get down to 1 mSec but even that is not really fast enough to catch the low end of the servo position range.

Which is why the gentles device(s) were developed.

Well I guess I'm missing something relative to the Gentles device   -  or I'm still a newbie and learning.  How does the Gentles device work relative to the RC radio?

Yes I was just reading it!  In my case I would need the GentsUSB2 which would support 2 RC channels and low, mid and high pulse width outputs which would necessitate a Script as these pulse widths are not going to function with the Zoom Control Mode in CHDK, is that correct?

They do not offer a USB2 with the video out, I'll have to check with them and see if that's doable.

Correct.   The built-in zoom control mode counts the number of pulses to determine what to do.  It does not measure pulse width.
