The manual says they're pre-hinged but then it has instructions on gluing in the CA hinges. It looks like they're already slotted & installed but not glued yet according to the manual. Then again, the manual also says the wingspan is 68.2" while the website says it's 63.75". Guess we'll have to wait to hear from somebody who has one.

I wonder how the Saito 1.25 would 3D it?
