This is my first model, while it came out great it is a bit fragile with PLA.  Perhaps with other materials it would be more forgiving.  That being said the weak point in this land skit is where it attaches to the S300 frame.  It broke for me but it was fun to design and print regardless.

Lastly, it was designed to accept the larger 1 Cell Batteries such as 210 mAh for longer flight times.
