trex 450 clone drifting

[windgat]

Hi I need help. I am beginning to learn to fly my Rc heli. Its a Copterx 450 V2 a clone of the Trex 450 V2. The head is setup all level and the blades are at mid pitch at 0, low pitch at -2 and at high pitch its at +10. The throttle curve is a linear line. As soon as it gets light on the skid the heli starts to drif to the left and to the back. I know that a little bit of left drif is oky but this is a severe drift to the left and the back. The heli CG is level. Can any one please help.

It has a brushless moter and esc from my old walkera 36 HM and a Flightmax 2200mah lipo. The radio is a JR 2610.

Thanks

How'd you level the head and how did you test the CofG?

Where did the drifting occur, was it in an indoor test or outdoors? If outdoors which direction was the heli facing to the wind?

Hi I used the Finless video's and a Trueblood swash level tool. The CofG was tested by holding it at the flybar with my fingers. The test was outdoors on a windless day. Could it be the flybar perhaps

I was told to test CofG by SqueekyPete by putting everything on the heli that you would in flight (eg. battery, canopy etc), extending the blades to flight positions. Then holding the blade grip and blade, tilt the heli into a knife-edge position and see if the heli maintains a horizontal hold to the ground. If the nose droops to the ground (nose heavy), if it wants to pull back towards the tail (tail heavy). CofG to the left/right shouldn't be that much of an issue from what I've been told if you've placed all of your gear fairly central.
