hey Battleaxe, just subscribed, these vids are darn helpful,
I've been wanting to see a good comparison of hot glue vs other adhesives (titebond 1,2,&3, gorilla glue, Elmers, clear craft, spray adhesive, foam insulation, ect.) with metrics like total dried weight, strength of joint, ease of application/dry-time, paint and sand-ability, longevity to heat/water/crashes.
You could show different types of common materials and what adhesive works better where, in different types of joints: butt joints, tab in notch, flat lamination of two sheets, both with paper and without, wood to foam, aluminum to foam, servo attaching, control horns, reapplying skins, waterproofing, ect.
I know its a large undertaking to suggest, maybe a mini series on it, but a solid single place to compare actual materials and how they stack up would be very helpful. Some people are using Elmer's glue to save weight, some people are using gorilla glue and spray foam for more strength, some people live in hot environments and cant use hot glue, but nobody is doing it all and giving any feedback.
