Align 3G
3GX software, Version 3.1 -- and DELAY settings -- Watch out

If you're running a 3GX system, using version 3.1 software, take note.

The software seems to want to default to a value of "30" for Rudder delay, and if you're not looking for it in the setup menu, you'll pass right over it. If your rudder seems to be acting weird and wanting to blow out on you, check out this menu in the software:

Look at the value found in the box that is circled in the picture.

All six of mine had defaulted to "30". Further, following the instructions on how to set the delay (as described in the software program) doesn't seem to work as expected.

According to the instructions, you are to get the 3GX controller into the Gyro setup sequence, and specifically, the DELAY LED should be illuminated.

Then, you are to move the rudder stick and watch for the DELAY light to blink. That is SUPPOSED to be "0". If you move the stick to its stop, that is supposed to be "100". What I'm finding is that the process doesn't actually work!

According to the instructions, once you get the correct value in the DELAY window, you're supposed to push the SET button to record the value.

If you watch the box that's circled in the picture above as you're setting the DELAY value, you'll see the number being adjusted as you move the stick, and if you set the value to "0", it appears to read "0" as it should. But when pressing the SET button to "store" the value, the number changes back to "30" again.

The work around seems to be as follows:

With the 3GX in the Rudder gyro setup sequence, with the DELAY LED lit up, watch the number in the box circled in the picture as you move the rudder stick. When you see the value you want ("0" is what I intended) DON'T press the SET button. Just wait ten seconds or so for the Gyro setting sequence to time out. Make sure the STATUS LED is the correct color for your heli when you do this.

The next time you go into this particular menu, you'll see the value that you actually wanted to be set in the circled box.

I had a Trex 500 that I recently switched over to use the 3GX, and the tail was blowing out badly, and it was acting really weird with rapid changes in collective. When I discovered the DELAY was set to 30, I managed to change it to "0", and the tail now holds well and overall the rudder works as it should.

When I read this, I thought "Isn't rudder delay set during the rudder gyro setup in "set" mode? (push "set" for 2 seconds after initialization)"

And, isn't the delay set to either "green" on the status LED (Big heli - 500, 600 or 700) or "red" status LED (small heli - 250 or 450).

Or, am I thinking of something different?

I've been having the same problem with my Trex 500. I'll have to check its settings.

Hey.

Good find, I spotted the 30 delay already set on recent V3.1 upgrades, but never thought it was pre-programmed by Align.

However from personal experience I've found that having 30 set in delay in the 3GX is actually a good thing. On all the models I setup, including my own, I always set 30 and never have any blow outs. Tail holds rock solid through all manouvers.

The symptoms you are describing from the 500 can also be linked to a wrongly set "Anti Torque Compensation Direction", where the tail pre-compensation is then adding in the wrong input to correct for torque changes.
Overall tail gain, tail servo horn length, collective pitch range and head speed, can also influence how well the tail will hold.

You would think that, as I did, until I went back and actually read through all the stuff in the 3GX Rudder Gyroscope setup tab in the software a couple of times.

Here is what it actually says I've only added some extra line feeds to separate out the various thoughts presented in the text) I also highlighted some key sentences in blue:
Press SET button to select DELAY setup mode.

The choice of small or large helicopter is done by moving the transmitter rudder stick left or right while observing the color of STATUS LED.

For example, T-REX 500/550/600/700 the STATUS LED will be green. T-REX 250/450 the STATUS LED will be red.

The amount of rudder stick moved from center is the DELAY amount. When DELAY LED begins to flash, delay is at 0%. When rudder stick is pushed to the end, delay is at 100%.

Confirm the setting by pushing the SET button.
First, the RED / GREEN LED ONLY tells you that the gyro is set up for "small" or "large" helicopters, a rather broad term.

Second, the DELAY amount has possible values between "0" and "100", again, what the percentage MEANS is somewhat up for grabs.

Third, if you watch the status light as you move the stick left or right, you'll find that you actually have to move the stick quite a bit from center before the color changes. And you see that "flash" which is supposed to indicate "0".

I've found that setting "0" is actually somewhat difficult, and frankly, pushing the "SET" button doesn't actually confirm anything. Pushing the "SET" button quite often ends up with whatever number you think you're about to enter, being overridden and changed to "30".

What I've had to do to make the selected value of DELAY actually get SET as the actual value is to move the rudder stick until I see the desired DELAY number displayed (zero, for instance). Then, just patiently wait about 10 seconds for the rudder setup sequence to time out and let the 3GX system return to its normal operation.

Using the "SET" button to confirm the setting seems a big waste of time, as it doesn't work.

That is stupid...

I have really have had problems with my 500 on the tail with 3.1 and even changed tail blades to see if I could get it work better.. I will look at my settings and play with it tomorrow.

Are you running the 500 on large or small model setting?

Mine was also set on 30 but changing to 0 delay did not help. I did add some torque comp to correct a left nose piro tendency on hard climbouts. I just cannot get it to not lose the tail on high power setting backwards loops. It will blow out on the top if you really push the collective. My setup is 8s. It is like the boom is just too short with all the power of 8s.

TRex 700E, DFC, HV Combo, Ver 3.

Mine saves setting ok when pushing set button. Set mine to zero, was
default of 30. Tail is a bit faster than I want, may try 10 or 15.

Hey Tom.

When you say faster do you mean piro speed? If yes you can slow this by lowering the rudder ATV values, try 10% off the left and right travel limits.
If you're finding it's lively around centre, are you running any exponential? Most gyro manufacturers recommend 20-25% expo on the tail.

The delay parameter isn't really designed to speed up or slow down the tail piro speed, it does however change the signals going from gyro to tail serco. The idea of this parameter was to allow you to slow gyro commands going to the tail servo to allow for slower tail servos. As the gyros can send out signals quicker than some tail servos can respond to, this settings allows you to cater for this.
With HV and fast servos it can be used tune an optimum tail rotor feel which allows maximum gyro gain before any wag sets in.
It has been found on the Align HV tail servo that slowing it down using an in line drop down, to drop a volt going to the servo, has helped produce a better tail.

3GX Rudder Delay...

Thanks for the input. Piro speed is faster, and faster response at center. I have only flown until this test flight with the "default" of 30 on rudder delay. I don't have any expo on the rudder, none on Stunt 1 or 2 , and 20% expo on Normal flight mode. When doing pitch pumps tail holds well, I do get a 15 to 20 degree right nose yaw when flipping into Stunt mode from Normal. Fine after that. Thought maybe this delay change might stop that. Maybe the flight mode yaw is due to "delay" setting when changing flight modes.

How do you have flight modes? I have version 3.1 and I can't find flight modes. I've been working things out using DR and expo in flight modes in my radio.

Flight modes are defined in your transmitter. The 3GX doesn't do the "bank switch" that you might be thinking of.

In your picture above, the 3gx program and orange tabs that read "flight mode parameter 1" and "flight mode parameter 3". How do I get those tabs in my 3gx software?

Look at the top right corner of the window, same level as those three Flight Mode tabs you asked about.

Click the left/right arrow till you see the tab you're interested in, then simply click on that tab to open its menu stuff.

That screen shot is from the V3.1 software.

They don't appear.

Those are the only orange tabs I have ever seen.

Wait. Are those just referring to aileron and elevator? Because they are in the same position as those are.

And you are right. In my above post I was asking about bank switching.

There is something fishy about the window screen shot you posted.

Note that in the top left corner of mine it says "3GX V3.1". Yours just says "3GX".

Further, yours also has the orange 3G symbol and tells me you have a 450 helicopter set under "Type and settings".

Mine doesn't

What software are you actually using? Is that the old 3G GUI software instead of the current 3GX V3.1 GUI software you're using? Or is that a real early version of the 3GX software that you've never bothered to update?
