Well other that what the others have said Ill add:

Fly in ZERO wind.

If you DO get out of control and the plane seems to be lost STOP what YOU are doing. These trainer WANT to fly and they can do it all by THEMSELVES.

The HZ Champ does not need a lot of room to take off and land but give yourself DOUBLE the amount of room that you think is necessary.

Go easy on the controls. You do NOT need to slam the sicks to the side but instead hold light pressure and let the plane react. There is a certain amount of lag time between when your finger moves and the plane starts to move.

Above all else have fun, don't give up and it wont be long until its just another day.
