the servo arm becomes loose when power is not supplied
any idea why this is happening?

Loose?
Do you mean to say you can move the servo arm when no power is supplied?

when it is the servo acts like a normal servo

I dint quite get you here could you be a bit clear?

I the above mention solution don't work you could try adding a 0.1uf capacitor between the signal and ground line...it will reduce the jitter upto a certain extent

That happens if tail arm flexible, servo back slash error, loose connection rod, loose mounted servo or feed back from flight controller while at tricopter on a flexible stand/landing skid.

yes i can move the arm freely without any effort..and when i power it up.. the servo arm needs some force to move
akhilzid sir & himadri so what is the solution to this??

You should never force the servo arm when it is powered on. Doing so may strip the servo gears.

no i dont do that... i was checking  the connection and i noticed this..what to do?? is my servo okay??

The servo should resist movement while powered on. If you moved the arm, that means the gears may be damaged. Even while not powered, the arm should turn with some resistance and the sound of the gears. It should most definitely not turn freely.

but it is...

when powered on.. it moves normally with the sound of gears and some resistance

actually it does resist it when powered on.. but its loose when power is not supplied

That is normal behavior of servos.

guys i have a problem in multiwii gui/config
the sensor[i think they are called sensors] are not responding..
when i move my copter ..they dont respond and the shaking is not visible on the screen
HELP
some pics on the way

wait a sec guys.. i did some random stick inputs and the blue light came on ... the motors started working at 90% throttle.. then i unplugged it and now iam trying all random stick inputs but the motors dont arm why is this happening does anybody the stick inputs for fst4b??

Did you uncomment the proper sensor name in the code? MPU6050?

Or may be you forgot to click "Start" in GUI ? Can you see the stick movements in GUI?

Ya I can see...It doesn't happen in this guy's too
And as i said I somehow made  the blue led go on by some random stick movements. .but now I can't do it again and that is the reason why I am asking for help
The blue led went on and the motors were spinning..that means everything is fine..I just have to arm the motors

But where you able to get the sensor readings on the GUI?

And to arm the quad(should bring the blue LED on) push ur rudder stick to extreme left and wait for LED to go on!
Increase throttle to see if motors spin!
To disarm push rudder to extreme right and wait for light to go off!
The throttle must be in idle(zero or completely down) position
Did you try this?

I tried that but the motors won't arm..  this tx is nuts

Assign arming job to any available aux channel.

did you change any of the trims?
All trim except the throttle must be at the center...the throttle trim must be completely down!

thanks i was able to do it.. i had set a trim on the yaw.. now the motors are spinning
the problem now is that the motors are starting at 95% throttle.. and only the 2 motors in the front are spinning..the tail is still ..just the servo and the 2 motors work..
why is this happening??

Remove props, connect GUI , arm now ,take a picture and post.

tell me if you want any more pics

Look like you forgot to arm while taking pics.
