WOW, some serious mileage on the topic! I have de-bonded and re-bonded the wing skins on a Grumman Cheetah, very cool system very similar to hot melt glue, Aluminum bonding is not black magic, and can be easily learned like any other process, ( wet lay-up on foam?:)LOL ), it all comes down to comfort level. I think it is a bad idea for anyone with low experience/confidence/background, to be re-inventing the wheel. I think it is great to experiment as many of us do with this great sport, but it should always be undertaken with a modicum of knowledge of what we are attempting to do. As said in one of my past posts, I once ran across a stock KR2 that was all wood, the old guy did an amazing job and it looked perfectly functional. I will note that the wings were perceived as being heavier than others I had run across. I think in a situation like this it is best to pick a design one is comfortable with and go for it. Gary Morgan sure has some neat little planes, did he not once own a KR and was it not a feature photo on the group site? Red Trim? Plywood over foam will yield an identical bond to fiberglass over foam, your peel point will be the underlying foam in both cases. I would imagine the same would hold true for most any substrate over foam, the foam itself is the weakest link and more than adequate for the application as proven over years of KR flying and abuse.
