Yes, I have no collective.........

[PaulT]

Hi, everyone.

I hope I am putting this in the correct forum.

I have loaded the er9x on my FlySky Th9x and
after much confusion have most controls working.
(Well, the cyclics and a couple physical switches, anyway.)
That's good, for now.

What I still do not have is any collective response.

It works just fine in the eepe simulator but not on the bird.
(BTW, it's a 450 SE v2 juckyard clone. It has parts from everything.)

What am I missing??

TIA. Paul

post your eepe file ..... do you have your THR hold on perhaps?

you must have a line in channel 3 on mixes...... telling the controller that you want your throttle mixes with one of your pitch curves... I am assuming you have set up your ID0 pitch c4 (curve 4)

C5 is usually for ID1 (Idle up)

Post your eepe file and we can tweak it for you

[Westy]

your collective should be also set on channel 11.... in the swash menu.

Have a look at this thread and see if you can figure it out (half the fun

Under "Heli Setup", you have to assign a channel to the collective. For example, channel 12

The mix on channel 12 could then be this:

CH12 +100%THR Switch(ID0) noTrim Curve(c4)
+100%THR Switch(ID1) noTrim Curve(c5)
+100%THR Switch(ID2) noTrim Curve(c6)

Your pitch curves would then be curves 4,5 and 6 depending on your 3 position switch.

I put this in a separate message so it doesnt get so confusing.

What I posted above will work, but it's a little 'messy'. You really want it so that "100%" in the pitch curves represents the maximum collective pitch that you ever want, say 11 or 12 degrees. You also don't want your washout base to hit the head block.
To limit that, you can change the 3 +100% THR values to something lower, like 50 or 60. Whatever it takes to get your maximum pitch.

This still isn't 'perfect'. You would have to put the same number in 3 different places. So this is what I do, it should be self explanatory.

My "Collective channel" in setup is channel 12

CH11 +100%THR Switch(ID0) noTrim Curve(c4)
+100%THR Switch(ID1) noTrim Curve(c5)
+100%THR Switch(ID2) noTrim Curve(c6)

CH12 +44%CH11

Now I only have to change 1 number, (the 44% on channel 12) to set my maximum pitch. This is the equivalent of the swash mix value on a spektrum radio.

I hope that makes sense

[Westy]

yip .... same as me ... but i have my set up on CH11

Does not matter as long as you get the COLLECTIVE operating on the correct switch position and (ID1, ID1 and ID2)and corrolate that with the correct Pitch curve ...... Usually C4 = Pitch curve normal (ID0) C5 = ID` = Idleup......

C6 is Pitch for ID2 = Idle Up 2

So for example in normal flying mode.....
(IDO) you might only need to set up you Percentage on (channel 11 or 12 as above) to say 77% to get you full range of -2 deg pitch at zero throttle stick (6 oclock) and 10 deg at full (12 oclock)

(ID1) Ide up mode.... might need 90 - 100% to get full pitch range from -6 to +12......

Of course you will have to configure each pitch curve separately to get each pitch curve to work as it is designed.

Cheers

Here's my eepe file.
(Attached)

[Westy]

and that is not working ???? no pitch change in ID0 mode?

If not ... try c4 instead of C10
No real need to 9 point pitch curve.....

if that does not work..... are you sure you do not have your Throttle hold on?

Set up you ESC correctly?
Go through your ESC settings again.

I see you have no throttle hold settings anyway.....

[Westy]

..... ahhhh.... I see the problem.......

Try this ..... (Back up your old settings of course first)
Change your channels
to the following
CH1 +100%CYC3
CH2 +100%CYC2
CH6 +100%CYC1


And take off your revert Aileron off in you heli set up menu.

See how that goes
Try this Eepe .... modded off yours.

Not sure how you would ever get negative pitch with your curve 10 looking like that ...but hey.... who am I t ojudge LOL

PaulT:

I just made some changes in your set up and saved in your eepe file as 'model 5: 450 se v2' check if that works for you.
I did not change the set up much.
your Rx line up should be :
ch1 ail (right servo), ch2 ele, ch3 ESC, ch4 gyro/rudder, ch5 gyro signal, ch6 pitch (left servo)

here are the main difference, you can check the mixes:
1. your throttle curve is actually id0: c10, id1:c2 id2:c3 I did not change that. I kept your pitch curve for id0: c4 id1:c5 id2:c6
2. your ch1,2 6 the source is incorrect, should be cyc2,cyc1, cyc3 ---- cyc2 is your ail(rigth cyclic), cyc1 is your ele, cyc3 is your pitch(left cyclic) servo
3. your gyro switch setting is not correct, you can see in ch5 I change to 3 mixes, 1st line give you to fine adjustment of your gain with p3, line 2,3 gives you a HH when 'gear' switch is away from you (off), RM when gear switch is toward you (on)
so you can switch to either HH or RM and still ajust the gain for each mode. while the begining value for HH is set at 83 , while the default for RM is 43. both you can change it by turning P3 knob (labeled on Tx as pitch curve, knob on left facing you)
4. in set up I checked the p1, p2, p3 for you so when the knob are at center, it will beep so you don't need to guess where is exactly the center
5. I add timer for you in set up, so your throttle stick will activate the timer , I set the timer for you at 5:00, you can alwasy change that based on your need.

try it. if you have problem, let me know. Have fun.

Ps. make sure you have done calibration for your Tx before doing any real spin up. other wise your stick position, knob position may not be centered.
if you still don't have collective change, in your heli set up change your collective check

[PaulT]

OK, I've got it!

I had to invert the Collective and Ch2 and Ch6.

Very strange, to have to invert all three but hey, it works.

I have attached my file.

Thank you Kaos.

Thank you Westy.

Thank you Monkeyhanger.

[Westy]

No Probs ...... Glad you got it working ....I know you would

Happy flying! er9x is kind of weird for heli. what can I say, the geeks around here are all plane experts.

[Westy]

not me ..... I am a heli nut!!!! never flown a RC plane

[erazz]

I kinda.. well... like helis. :]

[PaulT]

Thanks Kaos.

After I got it working, I re-attached my ZYX which I took off, to get my controls straightened out.
Looks like I f'd it up, before I took it off. So, now I'm waiting for a new one.

As far as the geeks go, they say they they're into helis. Looks like we might have some influence here.
Maybe we can find a way to "work" it.

[kaos]

I kinda.. well... like helis. :]

with all those twists er9x made my brain, We will make you 'crazy' with helis. --- with questions and requests specific for helis. Just wait.

Bummer, actually I have a ZYX sitting in my drawer. when I get to it, I may need help from you for the set up.

Now back to your setting. I am still uncomfortable with your throttle curves. My understanding er9x throttle is from -100 to +100 , so your c10 actually start at 50% of throttle. I guess you have a very soft start ESC. Do you have a problem when you start to spin up at ID0?

I set mine with 5 point curve like this:
Id0: -100 -40 20 60 100 that is equivalent to what we are used to for throttle scale 0-100: 0 30 60 80 100
id1: 100 70 40 70 100 equivalent to 0-100: 100 85 70 85 100
id2: 100 80 60 80 100 equivalent to 0-1000: 100 90 80 90 100

I did the throttle curve similar to yours before , but it gave me incredible high head spd at mid stick (my mid stick pitch angle is set at +1 degree). what i figure out is er9x throttle is from -100 to 100, -100 is 0 throttle, 100 is 100 throttle. 0 is actually 50% throttle.
I had one of my 450 set up with stock T9X. then switch to er9x and found this out. I don't know why, but once I convert the throttle curve using the '200 unit' scale (-100 to 100), the head spd is back to normal.

Just had this thread cleanned up a little. Way off topic.

HIding the fact the quad lost to the heli?
yep, I did put a post in scratch pad. I think we need a dedicated catagory for heli user. check it out.
and the template er9x has for heli set up is inaequate and a couple places is not correct. for new users, it is a mess. (the latest version of eepe's template is better than the previous but can be improved)
I will be glad to put up a template and some explanation for new heli user to get into this easier. ONly I myself is still wroking the last few bugs in the area of setting up the heli from scratch using er9x myself.

[Westy]

I too set up mine from scratch and it is working awesome!
