I was given a Nemesis II and a Tom Niebuhr Scorpion that need recovering. Both airframes are pristine but the old silkspan covering has become quite brittle. There are no signs of them having been flown. The Scorpion, although having tip weight, balances evenly on the fuselage centerline. It appears to have been built as per the plans as shown on the B. Baxter site and perhaps the recommended tip weight? Should I be adding more tip weight? Also, the uncovered wing is torsionally quite rigid. Should I add sheer webs? Anyone have any experience with this design? It will be used as a sport flyer with an Enya 29 with pressure.

            I planned on recovering with Monocoat just to get it off the bench in a hurry and move on to the next project. So I will add 1/32" sheer webs to give it a bit more strength and keep the tip weight as is.

         Thanks for the help.

             Thanks for that info. Just checked the uncovered wing (got distracted) and the spars are spruce and shear webs were placed on the trailing edge as you remembered. What's interesting is that it was built by a prolific builder who built everything from hand launch gliders to giant scale RC but didn't fly C/L Combat. Was the sheer web suggestion on the plans? I'll cover it as is.
