I liked it so much that I have decided to go bigger so I ordered the Sweitzer plans from Jerry Bates Plans. I also ordered the fiberglass cowls at the same time they were built by Bob Sealey. I contacted the 2 kit cutters listed on Jerry's site and the 2 that I talked with did not have the files for them but both said that they would see about getting the files (BCM laser and Bob Holman Plans) Bobs daughter sent me an e mail in late Feb and said that they were going to start cutting that afternoon, A week later I got the box of wood. $350 plus shipping, NOT BAD. I ordered the nose light and canopy from Vic at vic@vicrc.com the cost was about $67 after shipping.
The plans for this are huge, 4 1/2 sheets 3' by 9' the wing span is 96" and it is around 5' long. I plan to use 2 Saito 91 four stroke engines at this altitude but I may think electric as the build goes on. I use an Airtronics SD-10GS radio and plan to put a light kit in the plane.

I spent some time sorting my lumber before starting so that I could find what I had.These are some of the stick bundles, I may have to get my table saw out but I shouldn't need to buy much extra wood.
