Complete newbie here, but can someone provide some info / links to scratch building a heli fuse.
I can figure out the building part of it, whether it's wood, fiberglass or whatever, but what's the easiest way to go from drawings / pictures to plans?

Well, hmmm, tough one there. Most of us have found that all that work is about 3-5 times more expensive than buying one already laid up. Converting the plans from views to actual stations and such I cannot answer. I have only done such when I have the stations.

In other words, it just isn't worth it unless no one offers what you MUST have. You might try over on scalerchelis.com, lot of skilled folks for scale stuff over there.
