At this point, it is best you follow pages 17 through 26 in the manual posted earlier, and go through the mechanical setup of the tail one more time.  There is not much we can do remotely, and it looks like a simple mechanical problem.

One thing is for sure. You should be able to get the tail to rotate when you rotate the main gear by hand in one of the two directions (with the heli fully powered off).  If the tail does not rotate when you rotate the main gear manually (either clockwise or anti-clockwise), then that means the mechanical setup is wrong.  You have to just take it one step at a time and figure out how the motion is transferred from one stage (or rotating part) to the next.

Basically, the motion goes something like this.  The motor rotates the main gear. The main gear rotates the tail gear (smaller of the two white wheels) because of the one-way bearing.  There is a rotating part with teeth on the top and bottom that transfers the rotation from the tail gear to one side of the belt.  The other end of the belt transfers the rotation to the tail rotor.  You can manually rotate the main gear and check where the motion is not being transferred.

Most likely the problem is placement and gap between parts so that one set of gear teeth is not properly touching the next set of gear teeth. Just like the teeth of pinion gears on the motor shaft touching the main gear teeth, we need to make sure the teeth of the various gears touch the teeth of the next part.

will try to open the tail section and let u know

Did you figure it out, or are you still travelling ?

Dear Mr. Anwar, Thank god u responded i thought i had u pissed with me for asking so many questions. yes i opened up the tail section. The belt looked to be loose as it was dangling (enclosing pics) so i tried moving the tail section a bit backward. After this change the tail rotor rotated fine only when the tail section was on the verge of falling off from the tail boom, i could not screw it there as there was no space left to screw. Does it mean that i would have to cut the belt (but that would be idiocy on my part as i assume the joint belt would not take the load) kindly suggest a remedy like is there any screw that helps in tightening the belt. I am also sending another pic where i have inserted the questions in the pic.hope u would be able to figure out the problem if any.   

Ok, let us take them one by one.

1) Your belt feels loose on the back side most probably because you do not have it correctly placed on the rotating pulley/gears on the other/front side.  I have attached an image, so make sure the belt is correctly placed on the pulley.  Once that is done, you will not find so much slack in the belt, and you should be able to fix the tail rotor properly with enough tension in the belt.

2) If you asked why the rudder servo is not moving in the last picture, you have to confirm whether you tried moving the rudder stick, which is the same stick as the throttle in mode 2 flying.  So if you move the throttle stick left and right, and the rudder servo does not move, you have to check your connections again (re-read this thread for the connection details !)

BTW, if you are unable to check just basic build issues yourself by following the instruction manual, I would strongly suggest that you do not attempt to fly the heli on your own.  Again, I do not mean to discourage you, but you seem to be struggling with the basics, and an expensive crash is not going to be fun 

See if you can get any sort of help nearby, or wait until you can get some elsewhere.

Dear Mr. Anwar, thanks again for the advise. i have tried moving the rudder stick but nothing is happening so i guess its back to the checking of the connection. Regarding the tension of the belt rotor had the tail assembly already fitted when i received the heli. But as advised by u i will open up the things and try to locate the problem.warm regards

Dear Mr. Anwar, Have disassambled the entire tail and will be redoing the connections step by step. will keep u informed.

Did you figure it out yet ? 

Dear Mr. Anwar, Sorry for not being able to answer earlier, i was out of gangtok for the last 4 days, wife wants to renovate house so had to go and see and get some things, anyway thats my problem.. i have managed to connect all the things together and now the main rotor as well as the tail rotor is working fine now only thing left is for me to stick the stickers on the canopy and fit the training gear. will keep u updated of any fatalities or problems if any. thank you for taking all the time out to help me out.

Great ! Glad to hear that the mechanical stuff is OK now. 

Just make sure the swash plate is level/flat before you try to hover.  And keep us posted with photos/videos.

will do for sure boss.

dear mr anwar finally got everything connected even the training kit, but when i tried to fly it everything worked proper main blades, tail blades everything i mean. it made a lot of noise and the rotors also rotated in the corect direction but the heli simply did not leave the ground even on fool throttle. will try to send u a video by tomo.regards

your pitch seems to be reversed !
which means when you increase throttle (for mini titan) - the swash plate should move downwards & upwards when you decrease throttle. please check these responses and get back.

You mentioned earlier in the thread that the swash moves down with increasing throttle.  Is that still the case after reconnecting everything ?  If not, you need to fix that.  If it is going up with increasing throttle, you can reverse it using the appropriate switch on the TG1000M unit.

If the swash is moving down (in the correct direction), it may not be moving down enough.  Please try repositioning the servo arms of the 3 swash servos so that they move down enough to give you positive pitch on the blades.

dear mr anwar sorry for bothering u again and again and again, i have checked every thing including charge of battery but the heli simply does not lift off even at med or max throttle. i am enclosing some pics of the swash which are levelled. kindly advise

dear mr second chance, thank you for taking the time out to assist me but the pitch is in the correct direction , upon increase of throttle the swash plates moves downward and upwards while decrease of throttle.

can you give us your pitch angle readings please.

dear mr.second chance it is 8 degrees. However i am not sure i know how to read the pitch angles. I have a thunder tiger presion pitch guage (pic enclosed) but could not find anywhere in the net on how to use it. 

you could visit www.raptortechnique.com and you should find all the info on using the pitch guage and the likes.

as regards the 8 degrees, it makes no sense till you have gathered how to take the readings on the guage.

as regards the pitch guage in the pic, as far as i know its meant for 30 size and above helis. you need to purchase a guage for mini helis. there is one manufactured by align and can be found on the rotor website.

finally, i would suggest after going thru all your posts that it would be advisable if you hook yourself with another experienced heli flyer and learn the basics else you my friend will be wasting a lot of money on these toys !   

regards

Please see the video here to see how a pitch guage is used : 

http://www.rcindia.org/rc-general-topics/propeller-what-do-we-understand/msg3157/#msg3157

so won't that that pitch guage for 30 size heli do service on a 450 size heli like a mini titan or a trex450?can't think of any reason,why not.except for the blade length wts the difference?.

It is only a question of the gap that holds the blade. So the issue is that of the "width" of the blade.

If it is too wide a gap (suitable for larger blades), then the smaller blade will have some "play", which will make it difficult to do accurate measurements.

well.thats sad.im heading Prem's way i guess. .hv already ordered one for my MT E325. .thinking of brighter side,i'll keep it for future use on bigger helis.

BTW, there is no rule that a 30 size one does not work for the smaller ones.  I use an Align one which works from the smallest all the way to 90 size.

So some work for multiple sizes, and some don't.
