Nothing is indestructible but you may want to rethink your negativity re glued components - a high quality structural adhesive (glue) properly applied will cause the surrounding structure to fail before the bond! If you are worried about the "glue" failing I suggest that you never get in a new car, modern airplane, boat or just about any other type of conveyance along with lots of steel reinforced concrete structures and such as structural adheasives are used extensively in most industries due to their ease of installation and, in many cases, superior clamping / bonding forces.
Good design is a compromise between art, design, engineering, testing and common sense.
couch - what you just wrote makes a lot of sense to me. Real world testing is the only way to prove what works and what doesn't whether it's a 2-stroke motor, glued a-arms, engineered, not engineered, or whatever.
Otherwise I find it odd that some people are so feverishly defending a set of a-arms that nobody's tested yet. Maybe this is more about defending the design processes of the "little guy" than it is about the a-arms. If it's the latter, I get that. I can see how my posts could be misconstrued as picking on the design process. I'll check for some feedback in March.
