Dear All I have recently purchased a mini titan ARF kit but have not been able to connect the electrical connections. I am enclosing some pics where I am facing problem, like how to connect the gyro to the receiver etc. I am not sure why I have got three more servos (blue) and the li-po battery (green). I am not able to connect the electrical settings owing to the above problems. Would be grateful if anyone could provide me with a detailed electrical connections of the gyro to the receiver, and the connections from the battery, speed control etc. More over I have not received a charger for the heli battery is it to be brought separately. None of the electrical settings diagram has been provided in the manual I received in the ARF kit. Thanks in advance for all the help.

MORE PICS OF MINI TITAN

If this is a Thunder Tiger Mini Titan, then you can fine many build threads on the online forums (you can find many by googling for "Mini Titan Build").  Here is one : http://runryder.com/helicopter/t308261p1/

You will need 3 servos for the swash and one for the tail.  Any others are extra.

For a typical 6 channel ccpm heli, the connections are like this :

1.  The brushless motor and ESC are connected by 3 wires.
2.  The Lipo battery and ESC are connected by 2 wires (typically one red and one black).
3.  One of the two swash servos placed on opposite sides of the frame goes to channel 1 in the reciever. This servo is called aileron servo.
4.  The other of the two swash servos is called the pitch servo, and it is connected to channel 6.
5.  The third swash servo (sort of in the middle) is called the elevator servo, and it is connected to channel 2 in the receiver.
6.  The ESC is connected to channel 3.
7.  The gyro connection with 3 wires (like a typical servo wire) is connected to the rudder channel, which is channel 4.
8.  If the gyro supports remote gain setting from the radio, then there is a single wire connection which goes from the gyro to channel 5 on the Futaba/Hitec receiver.
9.  The tail servo is connected to the gyro.

Thank you Mr.Anwar for your kind suggestion to solvinf my problem. I have one more question though. The Mini titan i got does not have the li-po charger. Will it be Ok if i use my e-sky belt cp charger to charge the titan battery. i am enclosing the images depicting the wattage etc. the black one is for the belt cp and the ace one is i what got with mini titan.thanking u in advance for your help.

Since they are both 3cell lipos, you should be able to use the same charger for both. It is not clear from the pictures, but I assume the balance connectors are similar (otherwise you have to get a convertor cable). As always, I would strongly recommend against non-balance charging.

Dear Mr. Anwar, Regarding the mini titan I received the following message from rcuniverse.org “Your having problem connecting your electronics because your trying to run a 6 channel helicopter with a 4 channel radio.” Is it so.
http://www.rcuniverse.com/forum/fb.asp?m=8852850
Coz I brought the item from rotor.co.in as they have described in the brochure

Yes, you never mentioned what radio you are using; and yes, you will need a 6 channel radio (or 5 at least) to use the Mini Titan.

You have what looks from the pictures like a 6 channel receiver, obviously you will need a radio that supports the same ! 

You can use a basic 4ch tx with that mini titan. The TG6100 unit you have is a CCPM mixer and gyro. So you don't need a radio capable of swash mixing. I have not been able to locate a manual for tg6100 even on TT website. There are two extra wires left after the usual control and I'm not sure what they are for. However if you have a tx that is capable of 120deg CCPM mixing it is preferable to use the it and use the tg6100 only as a gyro.

I stand corrected      I missed the fact that it is not a normal gyro that you are using, it is also a CCPM mixer and gyro together.

The connections I explained above are for normal CCPM setup, where the CCPM mixing is done in the radio (instead of the a special unit like the TG6100M).

Thank you Rajesh for spotting that !

Here is the connection setup that  I believe you will need.

On the TG6100M :

1. Plug in the two oppositely placed servos (that push the swash plate) into the AIL(L) and AIL(R) channels. You may need to reverse them if you find they are moving in the opposite direction.
2. Plus in the 3rd swash servo (the one that is kind of in the middle) to the ELEV channel.
3. Plug in the rudder servo to the RUDD channel.
4. Plug in the connection from the ESC to the THRO channel.

From the TG6100M to the HITEC receiver :

1. Plug in the first connection (with 3 wires black+red+white) to the AIL channel, which is CH1 in the receiver.
2. Plug in the red single wire ELEV to CH2 in the receiver.
3. Plug in the orange single wire to the THRO channel, which is CH3.
4. Plug in the yellow single wire RUDD to CH4.
5. Ignore the other two connections.  The green single wire is for remote gain adjustment, which you cannot do using a 4 channel TX (this is usually plugged into channel 5).  Not sure what the blue one is for.

You may need to reverse the rudder (tail control) and pitch (whether the swash plate goes up or down) using the DIP switches on the TG6100M, if you find they are not moving in the right directions.

NOTE: I had edited this post since I posted it the first time, so please ignore the contents  of any email notifications of the same.

Here is a pic for Spektrum/JR. Futaba/Hitec uses a different channel assignment for first three channels. Anwar has already listed the connections for Futaba/Hitec.

The blue and green wires were causing some unexpected servo motion. It works fine with them disconnected. But since I was not able to locate a manual, I decided against using the mixer in CCPM to be safe. The mixing in radio allows better control of throttle and pitch curves anyway.

Dear Guys thanks a ton for bth of ur valuable advices. I am attaching the portion i am finished with (frame and Tail) so would be grateful if u could show me some images (sorry for all the trouble) on how to connect the electricals. like
1)   I have no idea how to connect the receiver and where to connect it.
2)   I cant find a place a place to place the receiver battery.
3)   I don’t know how to connect the Esc to the battery.
4)   Is there need to connect the servos that came with the radio (blue in color) or are they spares only.

So please take some time out for this good for nothing guy and assist diagramitically. Have attached some pics depicting my problem.regards and thanks

Prem -

Either we are missing something, or you are not reading/following the posts in this thread correctly 

1) I mentioned before that you need 3 servos for the swash and one for the tail.  I am not sure why you are asking if the rest of the servos are spares, even after this was clarified earlier.

2) My last post gives you exact directions on how to wire the TG6100M unit and the HITEC receiver, not sure why you are not attempting to do that.

3) There is no need for separate receiver batteries on these helis (typically).  The main battery (Lipo) is connected to the ESC, and the ESC powers the receiver. If there is no "servo-like" connection on the ESC, then you will need to use the separate receiver battery, but most vendors avoid that to save weight and placement problems (like the question you are having now).

4) Where to attach the receiver and TG6100M to the frame is somewhat a matter of personal choice.  You can look up the pictures in other forums for where people have placed their electronics.  You need to make sure the TG6100M is placed in the flat manner on the frame (i.e, do not hang it side ways, since it is also a gyro, and it needs to be placed in the axis of rotation).

For example, see how one guy has placed his gyro unit in this picture.



Some people place the receiver in the space below the gyro, so that it is far away from the ESC and motor, to reduce electrical interference.  Others just hang it on the side of the heli, again away from the ESC and motor as much as possible.

BTW, I am not putting pressure on you to do something you are not comfortable with, it is always better to double check if you are in doubt    I have had a friend who was new to electric helis and did not do the right setup, he ended up with 10 stitches on his first Trex 450 (which is similar to the Mini-Titan) ! I would strongly recommend that you do the initial testing of servo movement with the motor disconnected or the main blades removed.

Also, if you bought this combo from Rotor Chennai, then you should have received only 4 servos (they may have supplied extra, because it is easy to strip the plastic gears in these when there is a crash).

Note that the combo has no separate receiver battery included, and the BLC-40 ESC does have a built-in BEC with power connection, so you should not need a separate receiver battery.  If they did give you any receiver battery, it must have come as a combo on the TX radio itself, not as a part of what is needed to build the heli itself.

And finally, after some tricky searching, found the manual for the TG6100M ! The only problem, it is in French    http://www.as-modelisme.com/images/files/Notice%20AQ0843.pdf

But you can see the connection diagram for Futaba/Hitec on the left side of the first page (the JR one is on the right side).  I have pulled it out and attached as an image.

Forget the two connections that go from Ch5 and Ch6 on the TG6100M to the GEAR and AUX1 channels on the receiver, as you are using a 4 channel radio.

Dear Mr.Anwar , thank you for ur valuable comments, i have mangaed to connect the heli but when i push the trottle lever up the swash plates just moves a bit even though the motor starts to run, guess i have to changge the servo reverse switches right? will keep u posted on my development and hoping for more of ur valuable comments.Warm Regards

When you increase throttle, the swash should move up (with all 3 swash servos working together), thereby inreasing the pitch angle of the blades (more pitch, more air thrown downwards, heli lifts up).  If the swash is moving in the opposite direction (ie, it is throwing air upwards), then you should reverse pitch using the DIP switches on the TG6100M unit.

Dear Mr. Anwar, when i push the throttle stick the motor just whirrs and the wings move in the downward direction, i have tried reversing the servos in the radio but still the same thing happens kindly assist. connection depicting images would be of great assistance. thank you

Prem - Again, please read my post carefully.

The first thing to check is if all 3 servos are working together (they all move up or down together when you increase the throttle).  If not, you may have to reverse individual servos in the radio so that they move together.

Once you have that figured out, the next thing to check for yourself if the "angle of the blades" are changing in such a way that more air is being pushed downwards (or post a video of the swash movement) as you increase throttle. If the swash is moving in the opposite direction (pushing air up instead of down), change direction of the "pitch" control DIP switch on the TG6100M (not in the radio).

I don't have Mini Titan, and your setup uses a very special gyro unit, so there is no way I can help you with connection photos.  But I feel you have more than enough information already in this thread to get all connections done properly.

Dear Mr. Anwar, I also have two numbers of 6 channel radios that came with my Walkera and Art Tech falcon heli. Would be grateful if u could tell me what things are required to be brought by me to enable me to use my mini titan heli with these radios. I have enclosed an image of my 6 channel walkera radio. Thanking u in advance for your precious advice.

Updated: This radio does look like it is capable of doing CCPM mixing (based on the DIP switch options at the back); but if your wiring is right, the 4 channel you have will work just like the 6 channel.  Rather than figuring out the wiring for this radio and using the TG6100M for just gyro purposes, I would recommend you follow the earlier posts, do your wiring, and start posting pictures of your current setup.  It is not a full computer radio to justify the effort needed.

Troubleshooting such issues is typically a case of breaking the issue down into basics.  For example, if you think your swash is not moving right, remove the connections to the motor, and you can post a video of what happens when you move the throttle stick.  If you do not have video capability, post two pictures of the swash plate, one with the throttle stick at minimum position and one with it on the maximum position.  With out such feedback, people will not be able to help you remotely 

thanks . will proceed as advised

Dear Mr. Anwar, Got the connections going but am facing some problems like when i press the trottle only the motor purrs and the swash plates move down. i am enclosing some still images of the completed heli after connection. i did not have to do anything with the servos as the servos had come installed when i received it from rotor.co.in. I have also uploaded the video files at http://www.flickr.com/photos/39694014@N06/?savedsettings=3647572655#photo3647572655      for you to have a look and see where i am going wrong.warm regards

Prem, I don't mean to discourage you, but can you take pictures like the picture 2 above ?  That is the only picture where we can actually see the connections and details.  I guess you are using some kind of mobile phone camera to take pictures, but please do so under a table lamp (or bed lamp), so that we can see what is going on.  The current pictures are taken in a dark area, and from too far.

One thing I do see is that the connections on the receiver are probably wrong.  If the "white" wire of the aileron is on the outside of the 3 wire set, then the other connections should also have their signal wires on the same location as the white wire.  Looks like they are currently connected so that the red, orange  and yellow wires  on channels 2, 3 and 4 are all against the black wire.  The white wire on channel 1 is the signal one; so the red, orange and yellow should be on the same side (you have to reverse how they are connected).  So connect the channel 1 cable with 3 wires in reverse.The white wire  should be towards the center of the receiver from what I can see, so that it will be on the same side as the other 3 single wire signal cables (red, orange, yellow).
