watch out for the heading lock take off pirouettes, if you are using heading hold.

heading hold will be trying to straighten the nose from the moment you turn on the gyro. This means that if you set up in a different direction to take off or put the slightest rudder input in on the way to the take off point the rudder will react. The heli won't react because there is no tail rotor motion so the rudder will try to correct more, by the time you take off the rudder might be on full deflection and the heli will pirouette until it finds its heading. It's not much of a problem to deal with, but it can be quite scary if you're not used to it.
