We do our best to champion the DIY-ers with Built it yourself kits, supply materials and parts for all various levels of fabricators. We are DIY people, At the end of the day we need to anser the question "does this make sense to buy". If it doesn't, then who are we trying to help? Guys that want to start a wing project without our (free) help, I wish them luck. Speaking as an experienced fabricator you'll easily spend more in tools to complete the job (not counting materials) than buying one of our wings.
One major cost that a lot of people overlook when taking on a project like a wing is testing.
Can you complete a wing project for under $500? i'll say sure.
Will it be as well tested as ours? Definitely not.
From day one (opened in 2018) we've had a engineer at a CFD desk doing constant testing. Every weekend we are out driving and verifying what hes come up with. Speaking as a racer Aerodynamics is by far the most humbling thing I've ever been apart of. Every time I say "yes that's going to work" i'm proven wrong. if you want examples please ask i'll be happy to share shortcomings. If you notice in this thread it's never yes/no. it's 'Maybe' and 'shouldn't work'. If the aerodynamics "expert" on your team and hes saying "YES" then you really should be verifying his work. Our aerodynamics engineer has been building racing cars since 2006. his cars raced and won in the daytona24 / Le Mans. We still verify his work, we know he's good because he's interested in our findings.
Mortal of the story we are here to help racers of all levels because we are racers.
