Before cutting the nyrod OR the metal ends...

Ensure that the sheath is FIRMLY anchored, preferably at least every 4 inches (or every bulkhead in the plane). There should be an anchor "bar" across the interior of the fuselage, just clearing the servo screws, if the srvos are more than 1 inch from the closest bulkhead supporting the sheath. If the sheath moves, the rod will flex and that means the controls will be sloppy.
(I usually cover the fuselage AFTER installing the sheaths... If its a slab sided fuselage with no lightening holes, the sheaths go in before the bottom is sheeted.)

Insert the unthreaded length of metal rod into the nyrod inner core, and thread the nylon onto the threaded portion at least 4 turns. This is the end which exits the rear of the fuselage.

Install the servos and turn on the TX and RX. (no wheels or arms installed!) Center the throttle, and center all trims. Then turn the RX off before turning off the TX. (servos are all centered and you can trust the rods to be within 1/8 inch of final correct length when you cut them)

Install control horns wth the holes for the control rods/clevices as close to being directly in line with the hinge lne as possible.

Pin the control surfaces in the neutral position.

Press output arms onto the servos with the arms perpendicular to the fuselage centerline.

Screw a clevice on the exterior end of each rod. Engage a minimum of 6 turns, preferably 15 turns.

Insert the pushrod and connect to the control horn.

Affix a clevice to the servo output arm, and hold it in position next to the nyrod, mark 1/8 inch down the rod. Remove the Nyrod from the plane. Cut on the mark. Insert the 1.5 inch all-threaded rod such that 5/16 to 3/8 inch remains outside of the nylon.

Reinsert the nyrod, screw the interior clevice onto the rod such that 1/8 inch of threads are visible between the clevice and the nylon.


For engine... set the carb at appx 50% throttle.

Don't forget to put "keeper screws" on each servo output arm...

Test all controls for appropriate throws.
