There are a few things that will help you as a beginner.

Make it light for indoor flight.....REAL light, the lighter the better.
Use Expo, and plenty of it.
Learn that rudder. Learn that rudder. (this is critical)
Learn to fly it slow. Dont be afraid to pull the power off. Cruise around at a speed just high enough to keep it airborne, and no faster.
Like any plane, the faster you fly, the faster it will maneuver.
Trim your plane so that when you pull off the power, the nose doesnt drop.

These should improve your chances of success.
