The bearing of the RDS-pin is made with a glide coated sleeve in the spar in front of the rudder.


Advantage: No warping under bigger deflection because of the axially relocatability. Simplified installation of the servoframe because small failures of the position will be balanced automatically. Very stiff steering. Good and solid bearing. Optimum force transmission.


Use: All models, especially strong resilient F3B and F3F models. Deflection is possible up to 80° without any warping.
