It seems that you need to perform a throttle stick calibration by moving the throttle stick to the max position (100% throttle )and connecting the esc to the battery (with the motor connected to the ESC) now the ESC should go in setup mode and as soon as you hear 2 quick beeps immidiately bring the throttle stick down to 0% throttle, now you should hear a confirmation beep followed by the normal music of the ESC.

This will change the abrupt motor movement and you will have a smooth throttle curve starting from 0% and not 10% like before.

to answer your second question irrespective of the servo horn direction the slider on the tail shaft should move opposite to the stick delection and the correct position is that if you move the rudder stick to right, the slider should move towards the tail box away from the blades and vice a versa.(this test should be done at rate mode of Gyro -light turned off)

Now another thing to check is the gyro direction small switch says NOR or REV so keeping the heli pointing on the left move the tail of the heli towards your self and the gyro should move the slider towards the blades if this does not happen change the small switch position.

I would urge you to watch the 450 heli tail setup videos, from Finless Bob etc. Please search the forum for earlier threads on this.

Getting this wrong may cost you money !

Thanks Mr. Anwar.

The current servo's setup that I have done in terms of directions have been done by watching the 450 heli setup video by Finless Bob.

Will watch the tail setup also and do accordingly.

Thanks again for the help....
