Switch orientation on 12z

[Mike J]

I posted this is the MA forum already, but hopefully if they cant answer the queation there, some of you 12z/14mz veterans can help. Iv'e got my Revmax all setup on my new fury extreme Thing is I would like to set the switch to "E" so I could have idle up1 say at 1750, and idle up2 at say 1850. Only problem is the switch is in the on position all the way back (normal mode) off in the middle (idle up1) and on in the nearest position (idle up2) Iv'e gone into the function menu and selected switch E but it doesn't give you the option of orientation of the switch. I see it gives you the option under condition select, but I dont want to mess with my idle up setup. Anyone with a 12z know how to change that? Or can it be changed? Its currently working on switch A in the same manner. And I could use it this way, I would just prefer to not have to mess with other switches. Having it all on my idle up switch would be nice.

On the 9Z, we generally use an OFS (offset) pmix to get past that.

yes, Futaba seems to like the on-off-on idea but really should offer
a menu item to change it to off-on-on (ala off-lo-hi). It's just software.

You could try using the Governor screen itself to do this ... go into Function screen and setup Governor on channel 7 with a NULL control (connect the RV to it), then in the Governor screen (under Model menu), assign proper "channel" values (RPM in the screen) controlled by SE. 50% rpm would be off, OFF and 110% would be the on positions (OFF is the positive end of the channel).

Could you explain how to do this?
Rcfan, Iv'e tried using the governor channel but it does not seem to work with the Rev max. Following the instructions I found here http://www.modelavionics.com/Jockey/RadioTips/FUTABA_14MZ.htm
Problem was when I was above 25% stick I could not get the green light to go out as they suggest happens when you are below 52% on the rate. No matter where the rate or the atv limit was, I could not get the green light to go out.

I've never seen a Revmax myself, but as far as I can tell the only problem would be using ch 7 for the governor portion. So select some other channel as indicated in the document you linked. The GOVERNOR function itself has no special meaning except it's what the Governor menu uses to know which channel to adjust. Other than that, it's just another channel. The new channel grouping used on the 14MZ (and 12Z) appears to conflict with the Revmax which is why it can't use 7 (it's grouped with the throttle channel #1). Anyway, give what I mentioned another try with Governor function on another channel and see what happens.

Thanks for the help Rcfan. I got it working doing the following: I plugged in the Revmax to channel 10 and assigned governor to that channel in the NULL position. I set the endpoint limit to 100% in both directions on channel 10 (governor) I then went into The governor menu screen and set switch E to (off/on/on) Switched it to ACT instead of INH in idle up1 and idle up2. Now it seems to be working correctly. With the rate below 53% and the throttle stick above 25% the green light is off, when I raise it to 53% it turns back on. Now when I go into the servo monitor menu, its showing me that at 53% rate (in the governor menu screen) the endpoint for the governor channel is 6%. Just as described in the instructions that came with the throttle jockey. All is working well now. I set the rate to 71% in idle up1 which gives me an endpoint of 50, according to the chart that will roughly give me 1700 hs with my current setup. Should be a good starting point. Now all I have left to do is setup my 611 and im off to the field. Any suggestions when it comes to the 611 setup on the 12z?

Glad you got it working.

Nothing special, just set it up like any other gyro. Try to select the LOWEST gyro rate that will keep the tail locked in HH (AVCS) mode, anything higher than that would be overkill (gyro's working servo harder for no reason). I also like to setup a knob for fine tuning it.
