RE: Ercoupe kit
I had a set of Ziroli plans and cut parts and sold them and went for the Balsa USA kit. I think Robart had gear for the Ziroli Ercoupe and it looks pretty good. The Balsa USA kit is really a work of are but you pay for it. Their gear looks just like the real thing and it comes with wheels and everything but the covering, paint, and radio I think.
