Step 15: Flight!
Your take off should not be a jam the throttle wide open and scream into the air kind of flight. Slowly increase the throttle to full and let the aircraft climb out slowly and make gentile banking turns.
On your first flight you should not try anything remotely aerobatic, you should climb to a good altitude and fly in slow circles around the area maintaining your altitude.
You should also make a few practice approaches setting yourself up for the landing.
Be aware of how long your flight has been.
Gas aircraft just cruising around can do so for up to 20 minutes depending on how much fuel you carry. I recommend trying to land for the first time long before that happens in case you need to circle around for another try.
