I haven't started on it, couldn't find enough information. I've already contracted an autoclave to do the post curing at a local air plane manufacture. The 60 layers is for the rear firewall and the front supports where the most stress happens. I already have an engineer working on the chassis, won't be for a few months till the cad files are ready for machining. I hope to get it done this year and get it ready for the big boys toy show for next year
