Introducing the QUADMULA SIREN R5 HD FPV Racing Frame. The SIREN R5 HD is the special product of QUADMULA that is designed for HDZero and features functionality, lightweight, and durability.

After a lot of research and work, we came up with a frame that balances weight and strength. We seek to make the weight of the frame as light as possible on the premise that the durability of the body remains unchanged. Not only meets the needs of competition, but also reduces the loss in the practice process.

To achieve such a compact frame, we design a new structure called “C-Lock”. It makes all of the arms fit more tightly with each other, brings better body stability and can apply more aggressive parameters(less filter) in Betaflight. At the same time, our design also makes the frame easier to assemble.

SIREN R5 HD uses QUADMULA custom premium carbon fiber, 7075 aluminum standoff and 12.9 YFS screws, we make the best product.

Apart from the above, for maximum protection we redesign the top plate to fully cover HDZero VTX, and only add 0.88g in total weight. Super light and strong.
We also consider the possibility of installing various equipment. SIREN R5 HD can easily install HDZero Race V2 Vtx or Analog Vtx, camera also can support both 14mm or 19mm, even we reserved a place for a 1000uf 35v capacitor. All to bring you the best installation experience.

QUADMULA SIREN R5 HD will be the best choice for you.
