Dennis,
Take a couple of deep breaths, sit down, and pick up the instructions!

The Ztron is pretty easy, especially if you are also an RC flyer. By that I mean I usually hook up a normal 4.8V nicad receiver pack to the "so-called" retract connector (please make sure you plug it correctly by looking at the instruction sheet). I always read the instructions because there are slight differences between the jmp-2 and ztron, so I tend to forget.

I think you have the Castle Link connector. First you need to install the castle-link software, so look at the instruction sheet.
Once installed, plug in the USB cable and board, then plug in the ESC using the throttle connector connector. Launch the CC software and then program away.

Some of this is iterative, since if you choose governor mode, you may need to go back and forth before with the Ztron you get the rpm you want.

Dennis,
As I think I mentioned somewhere else, I always program my ESC out of the plane (no laptop!) and not connected to the motor at all. That way there is no prop to worry.
When you plug in the ESC to the link and start the application, it will automatically talk to the ESC.

Dennis,
A few things--
1) Did you program a run time on the switches, prior to turning on for the test? The Ztron looks at the Dip switch when you plug it in to get the total flight duration---you didn't mention that in your post.
2) You might just put everything back to default on the Ztron----set all DIP switches to "OFF" and press the PB switch on briefly. This is after you go into programming mode. Then take off the prop for safety (because the motor starts immediately when you plug in the power in default mode), and try a test. You still need to put a duration on the DIP switch before powering on.
3) I wasn't aware that you could set a LV cutoff on the ZTRON (I have CLT3, Rev1.0). On my CC Phoenix 35 ESC, I am using Auto Lipo detection and a soft cutoff. As I now think I recall, you are using the A123 cells? I don't have any experience with them, but a 6V cutoff seems a little low for a 3s type pack (2V/cell). I do recommend the soft cutoff where the ESC just starts to throttle down instead of instant cut which could be exciting in a vertical maneuver!

Finally I really recommending making a small test setup that you can use independent of the ESC and plane. If you are already an RC flyer, you probably have everything. But even if you don't, it would only cost less than $20 to get the components (a cheap RC servo and a cheap 4.8V receiver battery--or get a setup that lets you use 4AA Alkaline cells. Or I am sure you have RC friends with some old equipment who might be willing to give you a freebie! Here is a picture of mine. with the Ztron hooked up. It is a lot easier to setup the timer using this than with the entire plane! Once you see the timer is ok, then you can battle the ESC!

Hi Dennis,

Glad to hear you got it sorted out. I just posted my settings, they may give you some reference points? Good luck with your 1st test flights. :-)
