depends where you get your lumber from. even when I went and bought from the LHS it only cost me about 20 bucks for a 2 meter and that was including the carbon fiber. the kit costs 67 bucks. The only problem with plans is they may not have a complete rib set on them. the trick I use to get rib sets off of plans is to use a copy machine then use a iron and transfer the ribs to wood works real well. another one is that I have rib set templates and trace them onto balsa.
