Hi

I recently purchase a MT that came equipped with one of these ACE RC TG-6100M Gyro + E-CCPM mixer

Had I known that this device was both a mixer and a gyro I may have made an alternate selection as I am using a FUTABA 6EXHP radio I have no real need for the mixer.

I would like to hear from anyone that has one of these (and hopefully some experience)

The Manual tells me to use my radio in aircraft mode. (Fine by me I fly mode 1, because I fly planes)

The manual contains very little information on anything else. From the best I can guess things such as mixing and throttle curves don't seem to apply when set into your radio.

Of course if you apply a throttle curve it will have an effect, but that effect is mixed in with what appears to be the pre programmed operation of the ACE mixer.

It's all very confusing to some one who is very new to heli's

dont know if this will help you

Yes , i guess this may help! I will try it tommorow morning , but where to i plug the White/red/black wire which will supply the power to the gyro ?

Red/black/white plug (AILE) from Gyro to AUX 2 in receiver pack - as per the above link... i would recommend that you read this link carefully before taking any steps..

Dude... did you make the post else where many years ago ?

1.  Discussion about this in this thread : http://www.rcindia.org/helis/mini-titan-problem/

2.  You can easily choose to not use the CCPM mixer on the TG6100M, and use the mixing in your Futaba instead.  It gives you better control over the settings. You can get a manual for the gyro unit here : http://mms.tiger.tw/upload/2010-3/20103159286.pdf

3.  If you are worried about not having enough channels in the 6 channel receiver to power the gyro unit (if you set it up to use mixing in the radio), just use a Y cable on one of the receiver channels to split it out.

I had copy pasted the post but made changes to it.
I wasn't able to correctly tell the problem so i just put the same here , which is the same as my problem. The thing in that post was that they did not fully resolve it i guess. I thought of posting this long ago but due to exams i didn't.

No problem   Do you have enough information to make progress on this, based on my above response ?

I guess i should be able to make progress , my main concern was that both the CCPM mixings were activate , how to de-activate either one ?

You don't have to deactivate.  If you use the eCCPM mixing from your radio, you will be connecting the swash servos directly to the receiver channels, and NOT to the TG6100M unit.  So whatever mixing that unit does does not matter. You will only be using the rudder/tail-gyro part of that unit.

And the wiring issue for it ?
I have an 8ch Rx on it. Can i use any channel for the source of power ?

Yes.  It would be convenient to use one of the un-used channels at the end (7 or 8 ).

It will need no control from the Tx right ?

Not sure I understood the question/concern. Can you elaborate on "no control from the TX" ?

If you mean the gyro unit being controlled from the TX, then that is limited to rudder and gain settings only (typically channels 4 and 5 in Futaba).

No , i meant the 7-8th channel which i will plug the power source to , will not require any controls right ?

Should not, just the power from 2 (of the 3) pins/legs on either of these channels. 

I am sure you know it, but remember to reverse channel 3, since this is Futaba.

Will do it

I am trying to set up my MT 325 for basic straight flying (not 3D)and need help. My set up details are given below:
1.   TX – Futaba 6EXHP
2.   Throttle Curve – 0 – 45 – 65 – 85 – 100
3.   Pitch Curve  - 40 – 60 – 75 – 85 – 90
4.   EPA - 100
5.   Idle Up Throttle– Not activated
6.   Idle up Pitch – Not activated
7.   Throttle Hold – On
8.   Revo- Not activated
9.   Swash – 3-S
10.   Swash Mix – AEP  - All at 50
I was looking for pitch angles of -2; +5 and +9. However what I was surprised to find is that when I take pitch angle readings with a pitch gauge the blades show different pitch angles at different positions (NSEW) of the rotor circle. Say if I name my two blades B1 and B2 then this is how the angles read:

Zero Throttle ( Stick full down)
1.   East – B1 -4; B2 -5
2.   West – B1 -1; B2 -1
3.   North – B1 -3; B2 -3
4.   South – B1 -3; B2 -3
Mid Throttle (Mid position)
1.   East – B1 +7; B2+6
2.   West – B1 +9; B2 +7
3.   North – B1 +7; B2 +7
4.   South – B1 +6; B2 +7
Full Throttle ( Stick Full up)
1.   East – B1 +10; B2 +9
2.   West – B1 +14; B2 +12
3.   North – B1 +11; B2 +11
4.   South – B1 +11; B2 +11

So even if I adjust my pitch curve it really gets me nowhere.
I have made sure that my swash plate is absolutely level at all throttle positions. My servo horns are 90 at zero throttle. Each push rod length is exactly as per the instruction manual. All servos by-pass the gyro except the rudder. All the controls react positively.
I don't think there can be so much variation in the pitch of the blades. What am I doing wrong? Please help.

hi pradeep
by the looks of it i think your blades are not tracked.. meaning both the blades are not in line with each other... pls have then tracked first and then both the blades will talk the same pitch angle and also check for a loose mixing arm or loose links..

Hi Pradeep,

It looks like your swash is not level so ensure that the swash and the washout arms are level when you are ar mid stick.

Dear Sahevaan ,

Here is how I have finally succeeded in setting up the SWAH uisng Hitec optic 6 Tx.

I have bypasssed all ECCPM mixing from TG6100. I use it only for rudder control and gyro function.

With 6 channel Rx u have a limitation of not able to use the remote GYRO gain but can be over come by using Y cable ( as mentioned above i have not experimented it so not sure) Or  set the gain on the TG6100 unit using a screw driver . I do it that way as u dont have to fiddle with gain always.


My set up are as folllows. i use Hitec HFS MT-06 Rx

  Left servo - Channel 6
  Right Servo - Channel 1
  Elevator servo ( the behind one) - Channel 2
  ESC  - Channel 3
  Tail servo to TG6100 unit RUDD slot
  TG6100 - AILE white red and black wire to channel 5 (used to power) use INH from  the Tx for this channel as u dont want to

change any thing .
  Normally channel 5 is used for remote gain function but as I have only 6 channels I have to use this for power and INH it.

  But if u have a 7 channel u can power it in 7th channel and use channel 5 for remote gain function and connet the green wire from

TG6100 to it.

  TG6100 (RUDD yellow wire) - Channel 4 on Rx.
 
  Now comes the Tx set up part.
 
  in Mini titan the SWASh plate moves down for positive pitch.
  Make sure all three servos move simultaneously same distance down at increasing throttle. This I have achieved using following   changes in Servo reversin menu and SWAH mixing menu.

PS : the servo horns to be perpendicular at half throttle not 0 throttle. But it will be almost perpendicular if you give 40% at pitch mixing at 0 throttle I hope this is understood.
 
  Servo reverse menu ( these are applicable to my physical setup ) may deffer from heli to heli depending on the
 
Reverse menu
  Channel 1 - NOR
  Channel 2 - REV
  Channel 3 - NOR
  Channel 4 - NOR
  Channel 5 - NOR
  Channel 6 - REV

SWAH menu
Channel 1 - +70
Channel 2 - -70
Channel 3 - +70


  GYRO - INH as we have used this to power the Rx dont want to change any thing using the gain control switch accidentaly.

Trottle curve

  1 - 0
  2 - 35 %
  3 - 50 %
  4 - 80 %
  5 - 90 %

Pitch curve

  1 - 40%
  2 - 50%
  3 - 65%
  4 - 75%
  5 - 80%

Here i get to hover just above the mid throttle and I am comfortable in that as I am a beginner. Also I use exponential function for Channel 1 and 2 for smooth manuers.


Never use the mixing function from the TG6100 and the Tx together that will take you for a ride.

Use it only if you are using a normal 4/6 channel radio with out mixing facility. otherwise they both interfere and give you a mixed vegetable kurma wiht out salt and pepper :-).

Hi Sujju and Amit
Thanks for your replies. You are right, the blades are not tracking straight. That is evident from the changing pitch angles. I have taken care with the levelling and also adjusted washout arms and pushrod lengths to get 90 deg at mid stick. Re- set up the whole thing and still no luck. My point is that even if there is a level problem, there has to be some consistency in the pitch angle changes. Cant be just random. Any thing else you can think of?

Pradeep

Hi Pradeep,

Check the following (even if you have not flown the machine )

1. Bent feahering Shaft some times these are stock bent slightly

2. Bent Main Shaft reason same as above

3. Bent / curved main Blades (wooden blades curve, espcecially the ones with holes in them)

4. Blade tightness that can also affect the pitch.

5. Bent Blade Grips (rare but can be an issue)

6. Bent Flybar


Now there may be a possiblity that nothing is bent and everything is fine on the machine and it's just the surface on which the Heli is kept which is causing the issue or we are not able to keep the Flybar straight enough at every position that may cause this issue. Normally I only measure the pitch keeping the heli side ways and rotating the blades I fix the Flybar using a Blade holder to keep it straight or use a button water level.

Thats what I am suspecting but did not have the heart to voice aloud. My concerns are the main shaft/ feathering shaft/Blades.Cant check the shafts visually. Cant make out. But the blades have been suspect right from the beginning. Do you think I should replace the head totally with a metal one and change the blades to CF and do a check?
Regards
Pradeep

Ok ... I have been slow but I think I have finally got the MT 325 set up. Needed to adjust the blade grip linkages. I had mistakenly thought that the link rod lengths given by the manufacturer are sacrosanct. Not no be changed. But obviously that is not true. These lengths are just an indication of a starting point. So after levelling the swashplate with a leveller and running a blade tracking exercise, I think I might have come to some stage of acceptable figures:
1. Idle-up - INH
2. Throttle curve - 0, 45, 65, 85, 100
3. Pitch curve - 25, 50, 65, 80, 100
4. DR - Normal - Ail 80%, Ele 80%, Rud 80%
          Step 1 - 100, 100, 100
5. Expo - Normal - -35%,  -35%, -35% (Futaba)
             Step 1 - -20%, -20%, -20%
6. Swash - A +50%, E+50%, P-34%
7. Pitch angles - Normal -2, +5, +10

Blades tracking well. No visible difference between blade levels.
Do the above figures make sense? Need some reassurance before I take it further.
