it is an ongoing discussion if you should use heading hold while learning basic flying. i say leave it off until you REALLY need it (like sideways, backwards flight)
why? you may teach yourself bad "habbits" with heading hold on all the time. you tailrotor setup might be completly off and you won't even notice.
of course it is a great help to start flying, but I think you are better off laerning without it.
this is MY opion and i do not want to start a flaming discussion about HH.
thanks
