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?

Quote from: Darshan for multirotors on May 06, 2015, 11:24:52 AM
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

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

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.

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

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?

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