SRT RC Servo Horns for Precision Control

Dial in precise, slop-free control with our range of servo horns for RC cars, crawlers, buggies, boats and aircraft. We stock clamping aluminium horns for maximum rigidity as well as durable plastics when you prefer a little give in hard knocks. Getting the right spline is key: 25T suits most Futaba, Savox and many modern servos; 23T fits many Hitec; 24T covers Sanwa/Airtronics. Check your servo's spec before you buy. Choose arm length and style to suit your linkage geometry: longer arms increase throw but reduce torque; shorter arms boost torque and centring. Single, double and offset arms help clear chassis parts and tune response. Browse trusted options from Hudy, Fastrax, Associated, Dubro and Core RC, with sizes, colours and hardware to match your build. We keep large UK stocks so you can get the parts you need fast, with next day delivery options available. Not sure what fits? Our friendly, knowledgeable team is happy to help you pick the perfect horn for your servo and model.
