You MUST balance out the head/main shaft first. You can use Osterizer's in situ test with much success, if you are carefull. Pulling the shaft and doing the roll test (roll the shaft on a sheet of glass (from a 8 x 10 picture frame works well) and look for high centers) is the best and most reliable (without actually checking run-out with a jig and guage).

You may see SLIGHT button wobble when you power up (indication of imbalance or bent shaft). This is usually caused by imbalance in head components. If it goes away with increase in throttle, it is negligible and can be ignored.

Don't even bother with tracking adjustment until you get the head reasonablly stable without the blades installed. Then go to Blade balancing. Be sure that you have the tension on the blade grips set equally as per the instructions in the manual. Then try to get the blades tracking (by adjusting the small linkages to the see-saw.

ONLY AFTER headis stable and blades are tracking, should you attempt to adjust the linkages to the servos to mechanically trim out the forward drift, if you want... Your bird should be a little nose heavy. You may increase/reduce that some by moving the battery further out/in, if possible. Unless the bird is way out of trim (2-3 clicks is not far out), I would suggest NOT attempting mechanical trim.

Hands-free-hover is everybody's goal. Goals are good things, even if they are unattainable....
