The Kittyhawk Akos is an innovative aerodynamic frame that uses vertical arms and strong 3d printed parts to reduce drag, maximize thrust, increase strength, and keep weight and costs low.
Minimal-profile arms, resulting in maximized thrust capabilities and superior flight characteristics (read below for more info).
Very strong structure with interlocking arms and tension bracing.
Lightweight -- 74g (without braces and mounting hardware)
Stiff frame makes for better response
Top and bottom battery mounting abilities
Parts easily replaced
Camera cutout on bottom plate allows for low stack heights
3d printed parts cheap and easily replaceable
battery lead holes to prevent bat-pads from tearing off during a crash
Ziptie and hardmount spots for vtx antenna
The vertical arms used in this design decrease the amount of parasitic drag typically seen in most multirotors that use flat arms. Instead of blocking a portion of the thrust column, the vertical arms maximize the thrust capabilities of the motors. With a significantly smaller cross-section, the frame allows the multirotor to respond and fly better compared to other flat-armed frames which have far greater surface area in contact with airflow surrounding the multirotor and thrust coming from the motors. Benefits include faster acceleration, higher top-end speed, and a quieter operation while maintaining the strength seen in most flat armed frames. Whereas a skinny arm frame would reduce strength for aerodynamics, the vertical arms do not sacrifice in order to optimize. Furthermore, my interlocking system used with the vertical arms makes arm changes simple.
The X layout of the motors ensures that the multirotor is perfectly balanced on the x-y plane, eliminating unnecessarily fatigue and wasted energy created by the motors need to compensate for an asymmetric, impure shape. The X structure on the bottom of the frame also helps grip onto the battery when you use a soft material/foam/soft side Velcro piece stuck onto the battery. It also grips the battery well, but a piece of foam or Velcro is highly suggested.
The braces used in between the arms also significantly strengthen the frame and help mitigate vibration, and it is highly suggested that they are used. There are 4 2mm brace in the kit, which can be doubled up to create 2 4mm braces or left as is as a lighter weight option. When doubled up, the braces act like a leaf-spring under high impact, bending under the stress of an impact instead of shattering.
While 3d printed parts may seem weak and feeble, these 3d printed parts are very strong and durable. They maintain the flexibility to absorb impacts without shattering, but also have the strength to handle a crash due to the unique, and potentially revolutionary properties of HP's fusion material. They also are low cost, allowing them to easily be replaced.
Thank you for considering purchasing this frame. You support is greatly appreciated.
