Proper assembly, installation and adjustment of the control linkages is critical to the flight performance of
your model. When assembling the control linkages, we recommend the use of vise grips or needle-nose
pliers for holding the pushrod while installing the plastic ball links. We also recommend the use of a metric
ruler or calipers to set the proper length of each linkage as listed.
Three dimensions are given for assembly of each control linkage required:
• Length of pushrod used (Rod Length)
• Completed length from ball center to ball center of each link (C to C Length)
• Completed length from outside to outside of each link (Overall Length; easiest length to use for
reference when checking with a ruler or calipers)
