CONTROL LINKAGE SOLUTIONS

When building a giant-scale airplane, you don’t want any guesswork with your linkages. The all-important connections between our servo and the control surfaces are absolutely tied to the length of our aircraft’s lifespan. There are several common linkage methods. You can use a solid pushrod of a rather short length for a direct control setup and, for longer distances, you can use a rigid carbon tube or insert a flexible pushrod into a guide sleeve braced securely within the fuselage for precise control. Another popular setup is to use a pull-pull system, which is very common for rudders on giant-scale aerobatic models whenever the rudder servo is located close to the cockpit area. Whichever method you prefer, the installation of these systems must be done properly to ensure the best results.

SERVO BASICS

For your control system to work properly, you have to use the correct servo for a given job. Many
