Hoku is the premier racing frame of WREKD Co. designed by Ari Uptimefpv Stehney.

The Hoku race frame is designed to be a perfect True-X racing frame, incorporating some more complex internal features and prioritizing rigidity overall.

The key selling point of this frame is balance. Its one of the lightest frames and most durable in its class, but doesn’t make any large sacrifices while still minimizing the unnecessary bulk that other frames suffer from.

The Hoku has proven to be one of the stiffest racing frames, and that translates to great resonance performance and tune-ability. To achieve this, the Hoku uses a arch keystone-like compression structure that causes the interior of the frame to be in tension laterally and longitudinally. This directly results in stiffness that won’t go away as the carbon wears down over time and will keep screws from loosening. When compared to frames that use an overlapping carbon sandwich, the full height compression interlock with equal force distribution along layer lines allow the arms to last longer and not delaminate.

The design process has consisted of over 300 soft revisions and multiple prototype carbon batches have helped me boil the design down to what I think is near perfection.
