THETA Servos

THETA Servos is the in-house RC servo brand of Shenzhen Yifengze Industrial Co., Ltd., a model aircraft electronics manufacturer founded in 2014. After years of OEM experience, the company launched the “THETA” brand in 2018, focusing on high-efficiency, low-consumption servos for demanding RC pilots and drivers. A key differentiator is NFC programmability—THETA was among the first to bring NFC tuning to RC servos, letting Android NFC phones adjust parameters quickly without complex wiring.

This collection covers multiple families: the Razor series (high-performance brushless HV servos, including waterproof IP67 options), Sabre minis, and THL/THM/THS lines spanning full-size, mini, and micro formats (plus special sets like the Kenny Ko Edition). Many models use durable metal output splines/gears and are built for precise centering under load.

How to choose: for 700–800 size helicopters, pick Razor-C1 for cyclic (swashplate) and Razor-T1 for tail; Razor-DH1 (cyclic) and Razor-TH1 (tail) are ideal for 550–600 and lightweight 700 setups, and can also suit small 3D fixed-wing needs. For cars, Razor-D1 targets low-profile installs (drift/on-road/off-road) and works with common gyros. For wet, dusty, or high-splash environments, prioritize IP67 waterproof models. Finally, ensure your BEC/current capacity matches the servo’s performance level, especially on HV systems.
