FISD:

Fully Integrated Servo Drive has both the servos slide into a pocket molded in the root of the wing (picture one). The aileron servo gets pushed in first and slides to meet up with an round aluminum servo arm like seen in picture two. Then you put a set screw on each side and the servo is in and ready to go. It drives the aileron using a torque rod from the servo arm to another connection where it meets up with a push rod made out of G-10 that drives the aileron. The whole system is, of course, made smooth with ball bearings. That part of the system is all set up so all you have to do is slide your servo in and put in the set screws. The flap servo then slides in to the pocket with the aluminum arm already attached, then you slide the G-10 push rod through the wing and attach it to the servo arm using a pin. You then put the pin through the flap and add a few pieces of wood to hold the ball bearing and you are ready to go!  Jaro includes a cover for the pocket that's the perfect size and is already sized for the multiplex connector.

The Espadita is the long awaited two meter from Jaro Muller. Jaro's mind just works differently than anyone else's and we are very lucky to have him designing models for us. Two of Jaro's goals when designing a new model is to have it as fast and easy to build as possible, and then have as much of his mass centered on the CG as possible. With the Espadita, he achieved both of these goals. He came up with a system called Full Integrated Servo Drive (FISD). He wanted a system that had no external linkages, like RDS but Jaro's special RDS, and a system that allowed him to move all the mass of the servos to the center of the wing. Try and figure that one out, and you will see why this model was two years late. So how does it work?
