Hey all My take on this is that you are free to experiment with any material you wish. After all if Ken Rand had not tried foam and dynel we may be covering our wings with wood or cloth. Everyone has there own level of comfort as the risk of trying new things goes. However if you use an unproven plywood or foam or whatever the responsibiity of the testing is on you. We as an aviation community have some intrest because if you fail to do the proper testing and enginering and then crash in a spectacular fashion all over the 10:00 news it affects us all. So as far as I am concerned buy some cheaper plywood and spruce. Build a couple mock ups and then load them to failure. Keep detailed records of the process and results. Armed with this information you can now possibly run the #s and make an educated decision for your project. Then make your reserch public so we can all use your research for the good of the comunity. I for one would be interested in what you find. If this sounds like too much work and you just want to build an airplane buy plans for an established airplane ( you should have done that already) read them and use what they recomend. Someone else has done all the research for you and there is nothing wrong with taking advantage or that. BE SAFE!!!
