I'm glad you asked!!
Here is a list of most of the major components of my plane. The total plane weighs 7 lb 13 oz so obviously this list isn't complete. I weighed everything before covering so the monocote isn't included.
I don't consider this plane heavy. It is built according to plans with the materials supplied. I do try to keep it light, but I mostly follow the plans.
