Recursion Helios 3.5" DJI O3 Ultra-Light Frame

Bearing the mantle of the Titan of the Sun, the 'Helios' was designed with a singular vision: to provide a platform for an ultra-lightweight high thrust-to-weight ratio 3.5" DJI O3 FPV build. Harnessing the divine spirit of its namesake, the build is destined to carve paths through the skies, bridging the mortal world and the heavens in its flight.

Embodying a true 'X' design, the 'Helios' accommodates a top-mounted TPU camera mount (not included), engineered for a Naked DJI O3 camera. This configuration ensures superior impact absorption and utmost lens protection without compromising the field of view, offering unobstructed, prop-free views during flight. For optimal agility and thrust-to-weight ratio, a Naked O3 Air Unit is recommended. However, the design is flexible and also supports a full stock O3 Air Unit. This can be later converted with some additional hardware which provides, a 20% reduction in weight.

The default base plate of the 'Helios' strikes a meticulous balance between weight and durability, proving exceptionally resistant to crashes during testing. If additional durability is desired, especially for weightier builds (i.e. 1408 motors with larger batteries), a 3g heavier 'Vanguard' baseplate can be selected to provide additional durability.
