Fahrwerk und Fahrwerk Klappen Sequenzer

[AndreasJ]

Dear Sir,

i have checked the function and found no issue....

Please setup your Doorsequencer like in the description below:

-> Setup Assign.Control

1) Retract.Gear -> Assign the switch you want to use.
-> TAKE CARE ABOUT THE ARROW BEHIND THE NO. -> It must point in the switch direction for putting the Landing Gear out.

2) Go to Menu "Set Name+Function
-> Select Retract.Gear, Select LG Sequencer
-> Select AUX 1, Assign Door Sequencer, Rename AUX 1 to Door

3) Go to Servo assignment menu, assign e.g at channel 14 Door, 15 Retract.Gear, 16 Door....

4) Go to control menu, Door -> Assign at controlled from: Retract.Gear

5) Go to Servo calibrate menu, now bring the Retract.Gear switch in Retract.Gear out = landing position.
-> Now Check the directions of the servos. Doors have to be closed and retract.gear have to be out! If not correct the directions.

6) Go to control menu, adjust the values for Retract.Gear Delay and Doors for Slow and delay belike your needs....

On my tests there it works without problems, even if i switch of and on transmitter.
Please don´t forget to set failsafe at the receiver, when Landing gear is pulled out!

Best regards.

On my head:
- gear (landing & doors) down it's with switch in down position. (backward)
- gear up it's with switch in up position (forward).
And in this way don't work.

The sequencer works good only in the reversed way:
- gear down with switch in up position (forward)
- gear up with switch in down position (backward).
But this is out of the logic.

When you broken the gear doors one time it's a little bit annoying on a model like mine... and I'm tired of doing tests.
I also tried to reverse the switch mounting direction on the transmitter, is always the same because after I have problems with the other models template (programs).

Dear Sir,

please note it is necessary to assign the switch correctly (direction of the arrow) in the control assignment list....

-> Please try to setup a new model as decribed in my last article.

Hallo 2m1986,

leider kann ich Deine Probleme absolut nicht nachvollziehen.
Fahrwerk und Klappensequenzer arbeiten bei mir einwandfrei.
Bitte halte dich genau an die Anweisungen von AndreasJ, dann geht es.
Bist Du dir beim Programmieren nicht ganz sicher, kannst Du die Abläufe auf dem Servomonitor anschauen oder Du verwendest außerhalb des Modells einen 2 Empfänger mit 2 Servos zur Anzeige der Funktionen.
So bleibt Dein Modell geschont.

You don't understand the problem...??? It's very simply.

If the control of the sequencer is setted:
- gear down with switch in up position (forward)
- gear up with switch in down position (backward)
The sequencer work good in anytime.

If you reverse this setting:
- gear down with switch in down position. (backward)
- gear up with switch in up position (forward)

(for me this is the more logical setting)

The sequencer doesn't work good because anytime that you turn off the receiver battery, the landing gear valve goes in up position. (only landing gear, not gear doors).
With a model of 22,6Kg... it's a bit annoying and I have broken the gear doors.

[AndreasJ]

I have done the setup in this way.....
i am quite sure you have set the arrow wrong!

Please send me your model data file -> we will check?

Please answer the following question:
Have you checked the arrow setting? behind landing geat in control menu?

-> i tried it with switch <2 , switched landing gear retract out = switch in keyboard direction
(arrow in control menu shows in keyborad direction too)
-> landing gear in, towards antenna direction.

Works all perfect!

In the next days I will check another time.
I will let you know.

Here a short video:

As you see, the sequencer works properly. (the time is a little short).
But when I turn off receiver and transmitter and after I turn on transmitter and receiver, as you see, servos lost the last position...

[2m1986]

I have try this evening with a new program and I have always the same problem:

Turn off receiver, turn off transmitter.
Turn on transmitter, turn on receiver and the servos goes to the other side (like the video).

CH 10 Retract Valve
CH 11-12 Wing gear door
CH 13-14 Tail gear door

Transmitter switch: 1 on the right.
Backward: Gear and Doors down
Forward: Gear and Doors up

Thank you for provideing the .mdl file, we will have a look into!

Something i could imagine is, is that you have to adjust the switch point of retract to another value like 0%...
If you switch the profi on, the switch will have pos 0%.... so you have to append this value, that the retracts will be opend by switching on....

Just try -10% or +10%

[2m1986]

Hallo.
On the real program of the model, I don't have switching point.
All servos are assigned with 2 position:
- Retract Gear: -30/+38%
- Wings gear doors: +93/-110%
- Tail gear doors: +99/-100%

On the mdl file that you have now (it's a new program made yesterday evening).... there is all probably assigned with 3 position (+100/0/-100%)
But I don't found any change with it, always same problem.

[2m1986]

Hallo Andreas.
I have tried now to setting the switches to 3 position and change the mid value from 0% to 10 (- or + depends of the rotation of the servos).

There is always the same problem... after to switch off receiver and transmitter, when I switch on, I have the servos that goes in the opposite position.

Have you any ideas?

[AndreasJ]

Dear 2m1986,

the problem seems to be with the slow function, i am sorry to say that, it seems that there are really is a bug ... we will fix it in the next version.

[2m1986]

Hallo Andreas.
Ok, the important thing is that now the problem is identified. (a bit late... but is identified).

Another thing that I don't understand (if you remember I also told to you about that):
On the sequencer, there isn't 12 seconds for close and 12 seconds for open.

If the total sequence goes over 12s with delay and slow, the sequence don't work.
And for my model I need around 14-15 seconds for a complete cycle of close/open.

Max.

Hella, Max!

I want to congratulate you on your insistent patience.
Others would perhaps have given up.
You certainly forced the MPX-team to improve their system.

with regards

Hallo Andreas,

[2m1986]

Hallo.
After others 3 months, any news about to fix this bug?

Grusse,
Max.

[2m1986]

Hallo.
Today I see the newsletter with the software update 3.56, but on the description I didn't read any news about sequencer....

Is really that's it....???

[2m1986]

Another month is gone...
Now it's the season for the meetings... news for the sequencer??

It born a child in 9 months, it takes the same time for a software update?
