What is LineMaster 2.4GHz?
LineMaster 2.4GHz is a control system designed specifically for control-line flying, combining the ergonomics of classic handles with modern 2.4 GHz radio technology.

More than just a transmitter and receiver, LineMaster is an evolving platform created to expand the possibilities of the hobby while staying true to its roots.
Built with pilots in mind
LineMaster 2.4GHz was designed around how control-line pilots actually fly. From the handle ergonomics to the firmware logic, every decision prioritizes predictability, safety and confidence in the circle.
LineMaster integrates naturally while quietly adding modern capabilities. This is not about changing the hobby — it is about supporting it, respecting decades of tradition while giving pilots reliable tools that simply work.
Why it exists
For years, control-line pilots have relied on modified transmitters, DIY setups and improvised solutions. While functional, these approaches require time, tools and experience.
LineMaster was created to offer a purpose-built solution, designed from the ground up for C/L pilots who want modern capabilities without unnecessary complexity.
From idea to reality
Developed through countless test flights and 3D-printed prototypes, refined with the support of Eduardo de las Casas and Bob Whitney.
An early prototype was featured in Model Aviation – December 2024. Today, LineMaster 2.4GHz is moving toward a robust, ready-to-use platform with one clear goal: enjoy and grow this amazing hobby.
What pilots are saying
