The white glue used in many ARFs may more correctly be in the epoxy family however the strength is nowhere near the strength of the 2 part epoxies I have used. Virtually no absorption into the wood - creates an interference fit at the joint typically used along with dado joints. It takes very little effort to disrupt these joints resulting in that wonderful "crack" sound. My only experiences with ARFs include SIG's Kadet Senior ($210) and a World Model Company Skyraider ($70). The Kadet Senior was fine and flew well. The skyraider had pieces rattling around under the covering in the wings and fuse requiring a total strip down of covering, fabbing new parts, fixing just a bunch of issues. Afterward it flew much better than my skills. RIP.

Grimmy - Appreciate the background. Not being a knocker. The only way to evaluate whether a product is worth buying is to have a reply from someone with 1st person experience with that product. For example SIG openly states that they over specify the wood content for the assembly of their ARFs as the assembly methods and materials (glue) are often inferior and they cannot provide any quality control over the product (this is a "near" quote from SIG's technicians).
