This model is for use with the Spektrum DSM2/DSMX Satellite Receiver.


  • No negative pitch for normal mode so you don’t slam the heli down if you pull the stick down to fast.
  • Don’t fly outside in wind in normal mode. You won’t be able to pull the heli down if the wind takes the heli.
    If you fly outside in wind use ST- 1 or ST- 2 which have full pitch curves which can pull the heli down in wind.
  • Lower Pitch Travel Adjustment to make the heli tamer
  • Low dual rates and positive expo to tame the heli down
  • Throttle hold on the RUDD D/R switch
  • 7 Point Throttle and Pitch Curves
  • TX Power=100mW
  • Channels=7
  • Protocol=DSMX
  • No Fixed ID
  • Stick Mode 2
  • If you need Stick Mode 1, 3, or 4 load the model into your transmitter then change the Stick Mode in the transmitter settings.


    Model 20 is for deviation firmware v4 and the DEVO 6/6S/8/8S/10/12/12S.

    * This model will not work for deviation firmware v2.1 or v3.

    Model 20-2 has Zero Degree Pitch when throttle hold is on.
    This will help minimize damage in a crash as the swash and blades will be at mid stick zero degrees pitch.
    This will also help prevent a boom strike.
    The swash does not move when TH is on.
    If you want control of the swash in TH to help you land in a crash don’t use this model use Model 20 instead.


    Set your ESC Li-po Cell Count setting to "AUTO". Default setting is 2 CELL.

    ESC Settings

    Functions

    6. Li-Po Cell Count - Make sure to set this to "Auto".
    Do not use the "2S" setting. You will have an extreme power/headspeed loss using the default "2S" setting.




Throttle Curve - These are the values I used then converted them to the deviation values and 7 point curves.

NORM - 0% 30% 50% 55% 60%
ST- 1 - 70% 68% 65% 68% 70%
ST- 2 - 80% 77% 74% 77% 80%


Throttle Hold is active on RUDD D/R switch




Pitch Curve

Normal: No negative pitch. Zero degrees pitch at mid stick.

ST-1: Full +/- 3D pitch curve. Zero degrees pitch at mid stick.

ST-2: Full +/- 3D pitch curve. Zero degrees pitch at mid stick.



Gyro Gain - These are the values I used then converted them to the deviation values.

Download the Configuration Settings File.

Right click the "model.ini " and select "Save Target As" or "Save Link As" depending if you are using IE or Firefox.

Install the configuration settings file into your models folder (See my How to video below).

This will over-right the current file so make sure that model slot doesn’t
have a model being used in it. If it does rename the configuration settings file
to another number that you have free.

Example: The file you downloaded is named model5 so change the “5" to another slot
number that you don’t have a model setup for. If you have model slot 6 open rename the file to model6

Tom, It seems like I had to change the gyro gain to get it to bind. How did you convert the values to Deviation values?

Also, the bind is very slow with my Devo 6s. The esc beeps about 20 times before it completes the bind.

I made a Tutorial and I am still adding to it.

Converting deVention values to deviation values

deviationtx.com/forum/how-to/2620-conver...-to-deviation-values


What did you have to change the gyro values to to get it to bind?
The slow binding might have to do with the T-Rex frame rate vs the deviation firmware frame rate.
I don't know what the deviation firmware frame rate is but here are the T-Rex frame Rates.

DSM2 Frame Rate: 22 ms
DSMX Frame Rate: 11 ms

Just saw this post:
www.rcgroups.com/forums/showpost.php?s=c...940518&postcount=714

Looks like I might have to increase the Gyro Gain in the model.
Also he used DSM2 instead of DSMX. I have DSMX set in the model.

I see that you used the formula
D =2*S -100

so 2*55 -100 = 10.

I changed it to 26 as a shot in the dark, and the tail held there but would not hold at all at 10.

So 26 in Deviation translates to 63 in Spek, right?

He said 70 plus percent range. If he's talking Spek, then that's in the ballpark of my 63.

I have no problem with my Blade birds running DSM2 with Deviation 3.? beta. There must be something different about the Align on Spektrum or maybe V4 Deviation?

That is correct. 63% gyro gain in Spektrum = 26% gyro gain in Deviation


I followed Aligns gyro settings in the manual and YouTube videos.
People on the forums are using settings close to these also.

Normal Flight: 55%
3D Flight: 50%


Deviation Values

Normal Flight: 10%
3D Flight: 0%


Here is a screen shot of my gyro settings.
I am going to increase them to 72% Spektrum value and see how it works for the binding problem.






You can try running in DSM2 and see if it binds faster. If it doesn't or if it doesn't bind at all go back to DSMX.

Maybe too late:
I think this is a question of correct trimming of the throttle channel (sounds like the esc goes into program mode). Make sure that you have trimmed the sticks and throttle trim set to center.

rbe: I calibrated the sticks, zeroed the trims and tried various values of throttle-hold above and below -100. Also tried different values of gyro gain in both HH and rate modes. Bind still slow.

Sometimes the orange satellite led stays flashing after bind and sometimes it's solid.(same with the stock Spektrum sat.) If I turn the heli on before the transmitter, the satellite does come on solid with binding.

Couldn't get the throttle range adjusted as per page 27 of the manual. I set up a linear curve form -100 to +100. I get continuous short beeps (as per step 3) but never get the 2 beeps that indicate the highest position was detected.

Tom: I am only running DMS2 since the two satellites I have are not DSMX.

I'll borrow a DX6i and compare, since I don't know what else to try.

With a DX6i and either the Spek or Orange satellite, it binds ready to fly in about 20 seconds. The manual (page 18) says DSM2 binding should take 5 seconds.

Same results with Deviation. So something else is causing the slow bind.

I was wrong about the gyro setting affecting the binding. Doesn't seem to help or hurt.

That is odd about the long bind time. I don't know what you can try.
I looked in the manual also and it says binding should take 5 seconds.

Should I leave the gyro values at Normal Flight, 55%, 3D Flight: 50%
Deviation Values - Normal Flight: 10% 3D Flight: 0% ?

Or should I leave them at 72% (44% Deviation Values) which is what I increased them to?
You said the tail would hold at the values I had before so a higher gyro value sounded good. Plus the guy on Rcgroups said he had to increase the gyro gain to get the heli to bind.

I have +26 (63 Spek) and -10 (45 Spek) programmed into the gear switch and was able to bind both ways. (Still a slow bind, but nonetheless a bind.)

When I had your original value of 10, the tail wouldn't hold. I've only been doing small hovers inside and have not really tested the tail-holding ability with pitch pumps, but it wouldn't even hold well enough for hovering.

I think the bind is flaky and it might have been a coincidence that his bound when he changed the gyro gain. I think he later had binding issues again and sent the bird back for a refund.

I removed the notice about gyro gain and binding. For now I am going to leave the gain set higher. Better to be set a little to high than too low and have the tail spin on someone and cause a crash.

If you do test the tail-holding ability with pitch pumps let me know what values work good for you and I will match my model to them.
I don't have a T-Rex 150 so I can't test fly the gyro gains. I have to follow what Align recommends which sounds too low.
I tried Deviation Gyro Values 10% in my V120D02V2 and the tail wouldn't hold either.


Thanks.

I changed the Gyro Settings and posted the updated models.

Gyro Gain - These are the values I used then converted them to the deviation values.

Mix Switch

Pos 0: 55%

Pos 1: 65%

Pos 2: 75%



This covers a good range of values. The first is what Align recommends, the send one is what you found good, and the third one is a value I found people getting good results with on the forums.

Looks good.

On the slow bind issue...

A couple of guys on HF have very fast binds and they're using DSMX. Another guy has very slow binds on 2 separate 150s and I believe he's using DSM2.

Not a large sample but there might be something there.

Model updated (2).

I just found out the Align manual was incorrect on the gyro values.


The model first posted gyro settings were:


Gyro Gain - These are the values I used then converted them to the deviation values.

Mix Switch

Pos 0: 55%

Pos 1: 65%

Pos 2: 75%



Updated model gyro settings are now:


Gyro Gain - These are the values I used then converted them to the deviation values.

Mix Switch

Pos 0: 65%

Pos 1: 70%

Pos 2: 75%


70% to 75% is the most common values used on the internet. Fine tune the gyro gain to meet your needs.

hey, this is an old post, hopefully someone can help.
I loaded this on my devo 10 with a align 150x GRS, in regards to channel 5 which is the gyro why is the src = AIL? shouldnt it be Ch5?
as for the pitch curve in normal model my heli takes off from beginning -100 to -60, at mid stick and above the pitch becomes negative and heli descends.

the Tx has gyro settings, the heli also has an advanced setup for gyro settings via bluetooth how do these two settings affect each other?
any suggestions?

nvmd, i fixed the settings in the file, for normal flight zero pitch start at 50 on the 7 point curve in deviation, and for the 150X GRS no need to set gyro gains in the TX is all controlled via bluetooth! all you need to do is set a switch on ch5 to switch gyro between attitude and 3D, Simple curve min/max -125/125 Mix0/Mix1.

finally figuring out deviation! so much fun

thanks
