how to fit a pushrod on to your model
First, centre all the servo’s to 90 degrees from the direction of the pushrod line
(important; once cut and glued, you will have no adjustment of the pushrod)
Using a straight lollypop stick and two clothes pegs, clamp the control surface straight & level to the wing/stab.
Begin with the servos fitted in position, take the carbon rod and (using cyano) glue one clevis to one end of the carbon rod,
Next, fit one clevis to the control horn,
Now, fit the pushrod with the clevis, into position, and mark and cut the rod to the length required,
Then refit to double check that the pushrod fits without pushing the control surface out of true.
Finally, when satisfied with the fit, glue with a small dab of cyano in situ, and when dry, add additional glue if necessary.
Repeat the above, with all control surface’s,
For biplane models repeat this using the second clevis hole to connect both ailerons of each wing, as with a 4 aileron model’s.
