In the world of 'One day...' I'd love to build a Cri-Cri. One day, when I have the time...and the space...and the money. When did you get your plans & what did they cost then? I've heard that they're no longer available from the designer, although I have no information about the veracity of this rumour.
What sort of things did you feel required more than basic sheet metal fabrication skills? Are there items that must be forged, milled or turned? Special tools? I've never even seen plans for a Cri-Cri so I'm a bit in the blind about what's needed.
But to have a Cri-Cri! Imagine the comments taxiing one at Orlando International...
