I still have a Nobler that was built 40+ years ago that I have thought of flying again. The fuel tank and covering keep it hanging on the wall. My first Thunderbird was built before the Nobler. Tried to recover, but, the balsa wood in some places was non exhistant. The Ambroid joints were solid enough that I broke peices of wood trying to rebuild. Remember we used to double glue the joints as reccommended in that time frame. DOC Holliday
Hi Doc, (and Ty!
)
Ambroid does hold up pretty good over the years as long as it was double glued. Testors and Duco are the same way.
Before anyone dies laughing, I was told this by one of the lightest builders on the planet: "CA glues are heavy".
Ambroid is some kind of acetate (or plastic stuff) dissolved in solvent. The solvent evaporates (and smells, but I like it!) and leaves the acetate (or whatever) in the joint. That stuff is really light! If you REALLY want to build light, you can (probably should) use an *Ambroid Type* glue except for the areas that must have epoxy. That, and properly done glue joints (no gaps, tight fitting), WILL save weight.
On a stunt plane, it will save weight versus CA usage. CA is great, but it IS heavy.
