Great Planes Top Speed - GPMB1050 - Manual (Page 10)

❏ 11. Attach the pushrod tube to the pushrod mount on your
particular engine. It is necessary to have the tube bend as
shown. This will allow for full movement for steering and
reduce the amount of throttle change during steering.
❏
12. Locate the 24" [610mm] braided pushrod cable and
the solder clevis. Use the following sequence to solder the
clevis to the braided pushrod cable:
A. Lightly sand the pushrod cable and clean it with
alcohol.
B. Insert the pushrod cable into the non-threaded clevis.
The wire should protrude 1/16" [1.6mm] into the fork
of the clevis.
C. Apply a small amount of soldering flux to the joint.
D. Apply heat evenly to the pushrod cable and the clevis
and then touch the solder to the joint and allow it to flow.
E. Allow the pushrod and clevis to cool before continuing.
❏
13. Install a brass Screw-lock Connector with the 4-40 x
1/8" Cap Screw on the throttle arm. Snap the Nylon
Retainer onto the screw-lock connector post on the
opposite side of the throttle arm.
❏
14. Slide a silicone clevis retainer onto the clevis. Slide the
cable into the pushrod housing, starting from inside the
radio box. As the cable exits the tube, guide it through the
pushrod connector on the throttle arm.
❏
15. With the radio switched on, install the servo arm onto
the throttle servo as shown in the photo. Manually close the
throttle on the carburetor completely. Tighten the cap screw
on the screw-lock pushrod connector. Check the throttle
operation with the radio and make adjustments to the
linkages as necessary for smooth operation. Use the
appropriate holes in the throttle servo arm to provide the
correct amount of throttle movement and to prevent the
servo from binding at its end points.
❏ 16. Once the throttle has been adjusted, slide the silicone
clevis retainer in position. Cut a mixing stick to fit inside the
radio box as shown. Use medium CA to glue the stick in
position. Glue the throttle tube to the stick, being careful not
to get any glue inside the pushrod tube.
