I tried to fly Hirobo Quark a few times but as soon as thehelialmoststarted to lift off (light on skid) from the ground, it drifted to the left and backward. I used rudder to controlt he tail spin but the heli just drifting to the left and backward. As the rotor speed increased, it drifted faster (heli was not off the ground yet, still kind of touch the ground). I tried to put on right aileron to offset thedriftbut it still did that and also started to tilted to the right. I backed down the throttle worried the right side tilted too much and crashing the heli.

Any suggestion to correct the left / backward drift to get the heli to take off and hover ?

Thanks,
