gB,
Thanks for the step by step. I'm sure that it will be helpful to many. What you have described is pretty much what I have been doing and you're right. it takes a few wings for you to realize how little epoxy you really need. I also think that the use of hairspray on the cores keeps the amount of epoxy [weight] penetration to a minimum. The only thing that I do differently is that I still glue the sheets together using Ambroid glue [love the stuff] as it sands so well.
One question though......Do you have any experiemce with fenestrating [cutting holes/sections out] in the core before you sheets them ? I had a couple of pattern planes from RC City that were built this way and the wings were incredibly LIGHT.
Thanks in advance for any info,
paul
