As I am building a quadcopter with body of T4 Quadcopter Mini 315 - thing:408363 but with smaller motors (DYS be1806) and smaller props (5-6 inch) I needed new arms.
Better ventilation ispired by thing:902936
Arms recreated based on original design
These arms should bring the size down to ~280.
Update 31/10/2015: made arms a bit shorter as there was still space left even with 6 inch props
