MAUS45- OK so I mixed up the filter for the turret rotation motor, but do I get partial credit for knowing that it was dropped between H and J?
Leong - Thanks for the info. There are too many disclaimers at the beginning of the thread to convert to Mode 1 for my electrophobia to consider it at this point.
I seemed to achieve the same result (drive on right stick, turret/gun on left) by rearranging the plug order of the channels on the receiver.
However, if that is the source of this issue, then I'll reconsider.

Benny- Yes and no - I will have to go back tonight to figure out where and when.
As I was trying to figure out which channel went where, I tried a few different arrangements.
I remember sometimes the servo jumped when I pressed the fire button, but that was all that happened, no sound and no flash.
Sometimes nothing happened at all.

Here is the diagram I was using when I was trying to install a servo on my pershing using a 4YF.
The only difference was I used the camera hold module instead of a delay.
Would it be the same setup?
This setup refused to work for me.
The most common result was that the servo would 'jump' when I fired, sending my IR beam a sunder.

One other variable here is the Spektrum has one of Randy's VBT chips installed.
But it can be turned off independently, so the fire button functions with out them.
I also have them on my 4YF's.

Dave, in that pic your using just a delay. (can tell by yellow shrink wrap) Like I said, that aint gonna cut it for you to be able to hold the barrel in place and cut off the elevaion input(sound) to the DMD. With just the delay module you have to hold the stick in the barrel (servo) position you want, hence the constant sound and no firing. The camera hold module (red shrink wrap) lets you get to the desired position then let your stick go back to neutral while holding barrel (servo) position hence no sound since you are no longer inputting to the DMD. This is
all on a self centering stick. Before the camera hold module was out, I still used just a delay module to slow the servo, but had to essentially do an elevation sweep shot to fire. I'd bring the barrel above/below to where I wanted to shoot, then let go of the stick while firing to hopefully have my IR "fall/raise" onto my target.
