Cermark Extra 300S Instructions???
 

I have just picked up a Cermark 60-90 sized Extra 300S ARF NIB. My problem is there are no instructions or plans inside. Cermark's site doesn't show this model, I think it's an older discontinued kit. The assembly is obvious, but I'm trying to get any information I can find. Where I should CG, Control throws, ect. Has anyone seen one of these? Any suggested mods?
Thank You in Advance!!!!!
