We built mine as a group buld. You have to know what you are doing and be prepared for it to take some time. I currently have mine listed here on RCu forsale. There was some adjusting, shaping , head scratching that went on but nothing insurmountable. Technology has helped alot with this . Plan ahead, be prepared for non perfect fits and have at it. I think one of the most challenging aspects of the build is doing the scale fowler flaps. WE used the robart fowler hinges and they work pretty good.dont be afraid to change some things and you have this forum to help
