HI guys , finally swash levelling in done. Checked the levels on both the extreme ends.
Will check the blade pitch tomorrow morning.

Cool after blade leveling just tail setup left

Why does the heli drift left while powering up......??can anyone explain

Its due to the tail rotor it displaces air as it spins ...thought heli is in hover still it requiers 8degree of tail pitch to compensate for torque of the main rotor so while doing tht the tail rotor displaces air to the right and pushes the heli to the left

So i need to continuously work on my aileron shifting it right...am i right

What do you mean by drift? Is it :
1. Heli moves to the right/left
2. Heli rolls to the left/right
3. Heli yaws to the left/right

@ Shannon: How did you deduce that 8 degrees of pitch is required on the tail rotor?

Well the answer is yes and no .......the thing is if u notice the heli actually hovers slightly tilted to the right in some helis it is noticble greatly in some it is not ..yes but driftcorrection is always needed left right back fort however good u have set your heli its always required

Shannon, I saw your video on youtube , setting the gyro(G560) and tail rotor.
I did things the same way you showed. The only difference is i have a analog servo.
The problem i am a facing is i get rudder movement only on one side. I mean if i give right rudder the head turns right but if i give left rudder nothing happens.
So i checked with the tail rotor and saw that the neutral position of the rudder stick is actually at the left extreme position. And thats why i dont get the left rudder movement.
 Can you please tell me how to rectify it

Well 8 degrees of pitch is required to compensate the torque of the main rotor well this is what is calculated not only in rc heli but in full scale real rotor craft too ...well in a real helicopter it is measured exactly 8 degrees by engineers but for us rc pilots yere is what u have to do ....when u view the heli from behind from the tail u have to of set the tail pitch slider to the left by adjusting linkage rod or physically moving the servo to get the ofset ...some people have made custome pitch gaugeto measure this but i usually ofset the slider then hover if the nose remains in one direction its good but if it starts rotating i adjust the linkage rod and if it still drift tht is it yaws slightly one click of trim sort it out ...

Can u pls tell me which gyro u are using....

Avionic G560 , the one you showed in the video

Ok ill tell u from start ok reset the gyro... Once u have done this..disconnect the servo then power back to ok now select the servo type in the gyro.... After this power off the heli connect the servo.... Now power on the heli but do not move the heli or the rudder stick don't touch the tx at all.... Once the gyro initializes the servo will be In neutral position make sure the horn is 90 degree or get it as close to 90degree by removing the horn and setting it back again as close as possible to 90degree.... Once this is done view the heli from behind... Now the tail servo holder just losen it a bit so u can move it on the boom.... Now slide the holder on the boom to a position which will make the pitch slider exactly in the centre.... Once u know where u centre is.... Now move the holder so as to offset the tail pitch slider slightly to the left when viewed from behind once it is offset tighten the screws of the servo holder your done doing mechanical set up rest set up limits like the video.... And after setting your gyro please rebind the rxtx... Or the gyro will not initialize I had this issue and u have to rebind only once after setup

@rajathv8 drift in a heli is it moves to left right forward backward factors influencing this is the tail rotor CG and wind

Does it not depend on the final tail gear ratio?
If the main gear to tail gear ratio changes -> the tail rotor speed changes -> hence the pitch needed to provide a neutralizing torque also changes.

The gear ratio Is  calculated in order to counter the torque of the main rotor at 8 degrees pitch.... Usually the ratio is set to achieve four rotations of the tail rotor to one rotation of the main rotor

Okay. That makes things clear. Thanks

There is also the diameter of the tail rotor tht matters some people use 700size tail blades on 600size h elis for better tail athority

First dent in my pocket, even before the heli took off....burnt my tail servo

Use a normal 9grm u should be good for basic stuff

I think the reason why it burned was because it was a analog servo and you should have selected the frequency on Gyro 70hz to match analog servo type, another reason can be limits as you said the center position of the servo was extreme left

Welcome to the heli world...These things happen..Especially when ur dealing for the first time with electronics...Plenty of people here to help u out here.

+1 on Hellyflyer...

I had selected the correct servo, but i didnt select the correct extreme for the same.

Still wondering what made me buy that heli!!! this is the first dent in my pocket in 2yrs with my RC stuffs

its k things like this happen ......if u have a 9grm hxt900 use that or any 9grm servo its ok later upgrade to a good servo 

Will the HXT900 do the job??
