1) OK, so far so good, you can fly in a straight line. But at some point you have to turn the airplane. First, give a little forward elevator to make the climb angle more shallow.
Why? Because the aircraft already has a low airspeed due to the climb. Turning will reduce the airspeed further, which could lead to a stall. Nosing forward a bit before turning increases the airspeed and gives you a safety margin.
2) Now move the right Tx stick (left or right) to turn the airplane in the desired direction. Note that to maintain the angle of turn (bank), you may need to hold or move the stick back in the opposite direction just a bit.
3) Before the turn is complete start moving the stick back to it's original position. This will straighten the aircraft out.
4) You may have to apply a little bit of up elevator (back stick) during the turn as well, to help keep the aircraft nose up.
5) Now you should be flying more or less downwind. You will need to reduce throttle a bit, and ease the elevator stick forward, to level out the aircraft.
6) Continue making gentle turns near the ends of flying area, and flying long straight passes to get from end to end. Be careful to maintain your control input orientation relative to the airplane.
7) After making a few circuits of the field , setup for landing.
