Minimal Spacers for the Emax Nighthawk 280.
With these spacers you can "smash" your PDB & Flight controller between the bottom plate and the middle plate. This allows you to keep the battery in the center of quad (closer to the Center of Gravity) for better handling and performance. It also "helps" keep the battery protected versus being on the very top in the open.
I use this in conjunction with my minimal top plate and minimal camera plate.
