Reading all these "Truths" is somewhat -tome - comical. How the heck did we make it when there was slowing drying tube glues and slower glues I forget the name a powder that we mixed with water and let set-up for 24 hours on any hardwood items. When tube cements came on, they were just fine and Testors came out with a rather quick drying version, formula B. I built a number of models with that except there were some stronger glues took hours to dry except the powder stuff took a day and was stronger. There were several household cements that got into airplanes because they WERE THERE. The most popular model cement seemed to be Ambroid, but IMO it could not hold a candle to Testor's formula B.

Like other items that are marketed with certain folk saying this is the best ever, IMO Ambroid was an expensive waste. Now I would use SIG Cement a lot if the tubes did not have a .44 caliber hole in the neck. The cement is basically like the old Testor's B, and I still like it in some construction. I use to write to them and try to get some change. Never happened.

Then came the first epoxy. That was great for bellcrank platforms, and engine bearers along with landing gear mounts. Then about 1967 or so here came the 5 min. epoxy. Well then we thought we had died and gone to Heaven.

Now I use whatever is in reach during construction. OTOH epoxy is used for many hardwood stress areas, and I generally use 5 minute. There are certain times that 15 or 30 minute gets in there especially for big gas burners, but I do lots of structural reinforcement beyond any kit or plan. Actually I still do my own design models. I just make a few sketches, measurements and start cutting, some measuring, gluing, reinforcing, bolting/screwing wood and metal. Other than the mentioned structural centers, it is usually CA holding parts together. Whatever gets painted gets flown.

For you newbies, I say build from kits or ARFs the first several machines. Be careful with engine mounting, wing saddels, landing gear installation and use extra beefing up beyond kit instructions if you think it looke not too strong. Then you will have plenty experience to go as you please. NOW THE BIGGIE: NEVER fly a new model with a Center of Gravity (CG) aft of 28% (25% preferrd). Once you get use to it then go for whatever you have the heart to do!!!

BTW, with most models today, glue weight is - IMO - not a significant factor. Have Fun flying.
