How to Make Perfect Fitting Wing Saddles for a Model Aircraft
This tutorial will show you a way to achieve perfect fitting wing saddles. It will not show you how to set up the wing properly.
Prior to performing these steps, the wing should already be mounted true and square to the fuselage using wing bolts or rubber bands and dowels.
For years I attempted to fit and sand wing saddles to achieve a perfect fit and was never successful. I could get a perfect fit in both saddles but by that time the wing wouldn't be level.
My solution is to sand the saddle as close to a perfect fit as possible and use small shims (when necessary) to level the wing. The shims can be 1/4" square pieces of 1/64" plywood or material of suitable thickness.
The shims will not be bearing the load of the wing. All you need to do is strategically place them where they'll keep the wing where it is supposed to be. After the wing is squared, leveled, etc., the wing saddle can be cleaned up into something presentable.

Tools and Materials
  • Shim material if needed
  • Epoxy and micro-balloons or Silicone sealant
  • Waxed paper, plastic food wrap or plastic iron-on covering (Monokote)
  • Masking tape
  • Spatula (balsa scrap works)
  • Single edge razor blade
Hi Chellie;
Quit a few years ago we used to make wing fillits and wing bedding using Sig Epoxy-Lite and it worked great. We would put Saran Wrap on the wing to keep the Epoxy-Lite from sticking to the wing during this operation and then would take a heat gun and shrink out all the wrinkels. Put enough on to make sure it was filling all the imperfections on the saddle and then bolt the wing back on. Wait overnight for it to set up and then you just needed to trim off the excess on the outside of the fuselage. It's not that hard to do and makes perfect wing beds every time............
