Part 3 of the sailplane refinish series picks up with old crazed gelcoat removal. After grinding down and sanding, voids and pits were discovered. The wings were covered with a vail cloth to provide a consistent surface.

I've got my LS3 at the same stage now. A LOT of work. The glass on the wings looks less 'porous' than yours but we added a vale cloth to the tailplane and repaired a crack on one flaperon.

Hi great video! How many labor hours took sanding sand gel coat removal?

Good question! Check out the last video in the series. Danny answers that question. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xOXi2Y3060w.html

Question: when it comes to checking the weight and balance. Instead of using scales - wouldn't be "more prudent" to build a strong u-shaped rig, connect the rig to the bolt holding the wings together at the CofG and then hoist the rig and hoist the entire glider at the CofG. Have a pilot sit inside and visually see the glider balance?

That method works on small models but not accurate enough for a full scale sailplane. Weight and balance is performed by raising the fuselage to a specified level then recording weight the main and tail wheel. Calculations are performed which provide an exact CG location.
