FM-A wings Durability

I been using FM-A chassis from the start when i joined the B-max Category and it was very easy to tune especially when i was a beginner but i notice the wings is easily to damage or even break. I already used 3 chassis and 2 of them has broken wings. even reinforcing it with glue it still breaks and am only using that “Burger” damper set for the sides and still ending up breaking the wings. so that got me thinking, does the sides wings of the FM-A is really that fragile or am doing something wrong.
