The Spektr Design Bureau has introduced flagship 15x7x3 propellers that have been tested and received positive feedback from the front lines. According to the developer, the product surpasses imported counterparts (HQProp of similar pitch) in thrust and stability.
When working with heavy loads, up to TM-62, the motors, controllers, and batteries do not overheat - this indicates the presence of a power reserve and extends the life of the electronics. Each series undergoes strict geometry and balancing control: the propellers are ready for installation "out of the box" and do not require lengthy fine-tuning.
The product is designed for octocopters and heavy quadcopters used for transporting goods, in agriculture, or when performing special tasks. As noted in the Design Bureau, the 15s are already working on the front.
The Design Bureau emphasizes that stable operation of a heavy drone with a payload is possible when using a fully domestic component base - Wattex batteries, the Ikar flight controller, Velesova Top regulators, Gorny TsOT motors, as well as propellers and a frame from the Spektr Design Bureau.
