Yep, the first time I flew in a gym I had about 40 seconds total airtime by the end of the night. The walls just kept finding my model! But heres a couple of tips:

Use the rudder! Its about more than just co-ordinating turns, the rudder becomes your PRIMARY directional control. You want the model to point somewhere you do it with the rudder. Learn to use it inverted as well!

Use the throttle! In an indoor environment your models can sometimes fly alot slower than you expect that they can, simply because of the low turbulence.

Use the vertical airspace. Immelmans, stall turns and split esses (all maneuvers which have a vertical element) can really help avoiding walls at either end of the gym.

And finally, master the hover and torque roll. Use these when you get weary of avoiding walls, you should be able to fly a whole battery out just hovering. A hover takes up next to no space!
