Has anyone built an Ultimate Bipe from Dan Marlowe plans? I was searching the web for plans and came across this link. http://members.fortunecity.co.uk/slmohr/rcplan2.htm What’s nice is that they are in dxf format. I downloaded them and scaled them up to 60 “ wing span. I like to cut my models from a CNC router so having electronic files makes it a snap. I was just wondering the outcome of his design. From what I can tell they look pretty close to the Goldberg.
