La Mamba is lightweight for a 9" X8 cinelifter. It has more punch and agility than any other drone in its class. The smaller motors can be used due to the compact staggered frame which allows further weight reduction.
The staggered layout of the arms is required to get the "best of both worlds" when it comes to camera placement. The issue with a centered camera like on the Banshee or Honey Badger, is that props can easily come into view depending on camera tilt angle and lens focal length. On the other hand, if the camera is positioned in the front of the frame like the Siccario or Moneyshot Mini, with the battery behind, the props have to be super wide to accommodate wide camera bodies like the BMPCC4K or the Freefly Wave. The solution is to have the camera sit above the propellers and forward in order to achieve unobstructed FOV yet maintain a tight propeller spacing that is crucial for flight agility and hitting gaps.
