I've owned a V3 for the last 4 months and after getting pretty good at it i decided to upgrade to the HBK2.

Im having major issues....

For some reason...it constantly spins counter clockwise. even with full trim to the right and moving the servo forward a couple of mm at a time nothing seems to stop it spinning.

The tail rotor seems to be spinning fine and my blades are fairly well balanced. I've also tried adjusting the gyro - and+ but nothing seems to work.

I read a suggestion of tightening the belt. Can someone please let me know how this is done and any other suggestions you may have to fix this.

Thanks guys.
