Citaat van EFlight Wiki:
Tracking - Clamp the helicopter to a bench and run the motor at hover speed. View the rotor disk edge on - you should see both blades going around at the same height. If one is higher than the other you can make it make less lift by holding the root in one hand the the tip in the other and twisting the leading edge of the tip down for a few seconds. A little heat from a hair dryer may be required to make large adjustments. Identify which blade is which by a piece of coloured tape on one blade.
Oftewel, buigen maar...!
