Post subject:  Rescue channel
Hi,
On my 250 helicopter I'm using a Spektrum DSMX satellite RX connected to a standard Spirit gyro (2.4.0 firmware). I've successfully bound my 12 channel transmitter so I should have up to 12 channels available; yes? In the Spirit software (2.4.0) on the "General/Channels" tab "Receiver Channels Mapping" page I see 7 channels on the left side of the page and on the right side of the page I see the 3 function pull down boxes are active. If I assign a "P" function the channel pull down box for the function allows the option of channels 5, 7, 8, 9, or 10; so I know the Spirit is seeing at least 10 of my channels.

In the software manual, section 5.7, it states that rescue/stabilization can now be activated by a separate channel rather than having to set up 3 banks for; no stabilization, stabilization, and rescue (and activate it with negative rudder gain). My current channel assignments are 1:TH 2:AIL 3:EL 4:RUD 5:Gyro Gain 6:PIT 7:Bank.

My questions are these;
I'd like to be able to control gyro (rudder) gain; banks; and rescue/stabi on 3 different channels. That would require 8 channels. I thought by the statement in section 5.7 that would now be possible. Is that correct?

If there is a way to do that I can't figure out how by what I've found in the manual.

Hi,

yes, it is possible exactly as you have written.

It is all described here:

Gyro and Banks you already have it setup to channel 5 and 7 respectively.

So you just need to select, on the right of that screen, function "F: Stabi function" and Channel 8.

Awesome! Thank you for the help. I didn't look in the "P" list carefully enough.

Just a suggestion; if I understand this correctly; The channel 8 stabi function has 2 states; on or off (-100, 100). If it could be done it would be good to make the number 8 stabi channel function like the number 7 bank channel in that there would be 3 states; -100, 0, 100. That would free up the bank channel to work independent of the stabilization.

Again, if I understand correctly; as it is now, I still have to set a bank for "no stabi", "stabi" and "rescue", bank 0, 1 and 2 respectfully. It is then triggered by channel 8 instead of negative gyro gain. Yes?

No.

What you describe is what you do when you want to use one channel only: you use it to change banks, and you set the gyro gain in the Spirit, having it forcely positive in Bank 0 and negative in Bank 1 and 2.

What you achieve with "P: Stabi Function" is to "activate the Stabi function which you have defined in the bank you are in". That's exactly what you achieve, when you decide to use Gyro Gain for that, with a negative value.

No more, no less.

You can define on each bank it's own different stabi action and settings and with Channel 8 in your case you can activate it, as like coco said you did with neg Gyro before.

In may case, I have on Bank 0 Rescue Acro with 70% to get away from ground, on Bank 1 Stabi Normal with 10% to get upright, this kicks in on Fail safe.
And on Bank 2 Coax to let my Kids and beginners play with my heli.
Rescue Channel activation is programmed on a spring Push Button as well as preset on Bank 2 selection.

Hi,
Thank you for the replies. I think we both are saying the same thing and are in agreement. What I was trying to suggest as an improvement to the Spirit firmware would be to change the number 8 channel so it can "read" 3 different values instead of only 2. That way channel 8 would; for example; give you no stabilization at value -100; you would get stabilization at value 0; and you would get rescue with a value of 100. No other channels would be required to use stabilization/rescue.

The way it is now you can't do that (if I understand). You have to "define" what stabilization or rescue function you want in each bank and then activate it with a signal on channel 8.

I'd like not to have to use 2 channels to do one thing.

Tomas,
What I said in the last post; is that something that can be added to the firmware in the future? That would make "Banks" and "Stabilization/Rescue" independent of each other. Thanks

I like the idea (it is one of the things which is confusing new-Spirit-comers) but I am afraid it will be a total change of approach for the Spirit FW... that's kind of the basic idea of how it's implemented...

On the other hand... will you really ever need to use Rescue while flying around in Stabilization?

I mean, I would never use Stabilization in general for helis (I tried it couple minutes and decided it is not needed once you are past the "FP heli flying"), so I find it hard to understand that you would even need to use Rescue in that mode.

I mean... are we really talking about real life needs, or pure speculation / playing around?

Thank you for the response. I'm not a computer programmer but I know enough that I understand changing complex code isn't always easy. In this case I think it would be worthy of consideration; I'll explain.

From your question, "do you need rescue while flying around in stabilization" I get the impression I haven't explained my thoughts completely.

The Banks channel is the most powerful feature of the Spirit operating system. You can have 3 different configurations and switch between any of the 3 in flight with a simple change of a switch. For example, if you want to compare 3 different Pirouette Consistency settings in flight you can do that with 3 different Banks. Or 3 different Rudder Delay settings. Or 3 of just about anything. But NOT if the Banks channel is committed to configuring the Stabilization/Rescue channel.

If you see my second post in this thread I'm suggesting the "Stabilization/Rescue" channel to work just like the Banks channel (-100,0,100). 3 choices not 1 on the same channel. That way you could have;

Bank 0: - (1)no stabilization or rescue (2)normal stabilization (3) normal rescue
Bank 1: - (1)no stabilization or rescue (2)acro stabilization (3)acro rescue
Bank 2: - Something different that has nothing to do with "Stabilization/Rescue"; maybe a different Pirouette Consistency setting or Cyclic Gain.

See what I mean? By making each channel independent they multiply each other. The combinations become very extensive and powerful.
