Either my vapor landing gear is invincible, or I'm just really lucky
I've bounced mine off of the ground doing loops too close to the ground MANY times, I've also snagged it on pipes hung from the ceiling in the underground parking lot.
The only part I've been able to break is the front wing support, but that was a SOLID hit to break that. I was trying to fly through an opening in a tree(yeah, I know...) at "high" speed, and snagged the wing on both sides. A drop of CA and 5 minutes of waiting and it was 100% back in business.
To the original poster, keep at it! It's a very good flying plane, but keeping it in the air in a living room definitely takes some experience. It still takes focus for me, and I can fly my micro 4 site around the living room.
