Bottom Side Wires Replacement
The bottom side wires are the most common maintenance item on every model of glider. Unlike any other wire on the glider, a bottom side wire break renders the glider totally uncontrollable and necessitates a parachute deployment. They can get damaged over time from hard landings, kinks, exposure to salt water, abrasion, aerobatics, and repeated use.
Replacing these periodically is also a good practice because it’s an opportunity to check components in the control frame and xbar-LE areas that are often damaged or misassembled.
This job requires new nuts, a special punch (on most Wills Wing and Moyes gliders), and hardware must be reinstalled with the correct tension to allow the tangs to self-align. After replacement I set the glider up partially to verify correct alignment of parts and load test the wires.
I will get your VG pulling like new again.
The VG system works best when several parts in your glider are as low-friction as possible. These parts wear, become dirty, need lubrication, and are sometimes misassembled.
I replace the lower VG rope, check the pulleys, bearings, xbar-LE connections, noseplate connections, keel slider, and basetube corner bracket, replacing or lubricating parts as necessary. Rope and parts are extra.
The upper VG rope, which goes along the keel, normally does not need replacing unless it is fraying. The lower VG rope starts at a point inside the downtube and needs periodic replacement because of abrasion and dirt.
This involves pulling the sail completely off the frame and disassembling several components to check for wear and damage. Highly recommended periodically.

Based on manufacturer recommendations and my experience, for any glider where applicable I recommend lubricating the keel slider area, tip wands and receptacles, battens, VG bearing, and glider bag zipper. I use a few different lubricants depending on the location/material. This will keep everything moving the way it should during setup and flight and help parts last to avoid costly replacements.
If your VG is getting hard to pull or your sweep wire is getting hard to tension, lubrication should help. It could also be something too tight or misconfigured, which I would find in a sail-off inspection.
New Sail Install
Instead of getting a new glider, replacing a worn-out sail is cost-effective if the frame is in good shape. It’s like getting a brand new glider for half the cost.
Wills Wing will make new sails for many modern-ish models such as the Falcon 3, Sport 2, and T2.
A Moyes Litespeed S or RS can be upgraded to an RX!

Mylar LE Inserts Recondition
Your leading edge sail depends on mylar inserts inside for a good airfoil shape. When the inserts become creased, your glider suffers in handling and predictable flying characteristics. The turn your glider has developed could be from this.
The creases are hard to prevent and can be caused by tight sail ties, racks, or folding the tips.
I remove the mylar inserts from your sail, use a careful application of heat that brings them back reasonably flat, and reinstall them.
I coordinate with a local professional who does a great job replacing entire panels. If it’s a small wear hole in an area that is not in danger of tearing further, I apply sail tape appropriate for the material.
