Siren R5 HD

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 t
