...there are very few planes in its weight class that fast!
How fast? As far as I know, the fastest it has flown so far (original or replica) is zero.

I'm not maligning the plane, just saying it has to prove itself first. I have always admired the design.

Drawing upon the performance of the Caudron C460, which shared some technology with the Bugatti, as a comparison I think 400+ mph might be realistic.

Anyone get a look at the replica up close?

Based upon what I saw, I'd say their goal concerning construction craftsmanship is "functional".

I'd guess that by "functional", he means that it is being built to fly, but not to win any cosmetic contests. I rarely try to make a "showstopper" when I build or restore... I simply want a good flying aircraft that looks safe, but not show quality perfect. One of my peaves in this area is fabric covering. Many will fill and sand, fill and sand, and fill some more. While it makes for a mirror finish, it adds weight and rarely enhances flyability. Rutan is another that chose function over finish. The early Eze's and Quickies called for leaving the weave unfilled on the bottom surfaces of the wings. He reasoned that the top surface accounted for the lifting airflow and warranted filling, but filling the bottomside only added weight.

What does "functional" in this context mean ?...form follows function...or fiasco ?
Let's just say that it is likely to be a structurally sound aircraft, but that is mainly due to the gap filling qualities of modern epoxy.

I’m no master craftsman… but even with that premise, I’d be hesitant to show off workmanship like that at a local fly in, let alone center stage at OSH.

They had gap fillers back in the thirties too.

When have you EVER seen another aircraft besides the Model 100 where the fuselage was an all-wood monocoque laminate?

de Havilland DH.88 Comet

de Havilland DH.91 Albatross Airliner

de Havilland DH.98 Mosquito

Focke Wulf Ta-154 Moskito

Osprey GP-4

Falco F.8L

To name but a few that come to mind.

The Bugatti 100P, while very attractive, is not the first or last wooden monococque monoplane, but it should be kept in persective that unlike all the ones I listed, it never actually flew.

Which is - to me - the bottomline of the design. It would most definitely end up on the "subzero" section of Topgear, but apart from that it's just a nice collection of ideas and some engineering calcs, not too different from the Moller Skycar or the nice pictures of rendered "designs" of "revolutionary" aircraft.

It will be interesting to see what the replica is capable of if and when it is finally flown. Regardless of whether it proves out the original's performance predictions, I hope for their sake that it is at least controllable and structurally sound (i.e. - does not hurt anyone).

I too saw the replica at OSH. Disappointing is my best term for it. I was expecting closer fits, better joinery, etc. I was also expecting things like formed plywood skins on the leading edges. It does appear that a lot of micro will end up making it fair... All that said, it will probably cost it a few pounds, but not a lot.

The biggest concern I have is that they still have to make two engines, driveshafts, and gearboxes tying things together all work well and not tear the system apart. Good luck guys.

Yep, Bill nailed it - disappointing. I'm not about to rain on their parade, but I would expect better craftsmanship for such an ambitious project parked in show center at OSH. It's also not really complicated joinery that came up short either - its capstrips not lining up with the rear spar (or falling a 1/4 inch short, bridged with epoxy), not wiping the excess resin glopped all over, simple stuff like that. The factory wings on my Hiperbipe are like fine furniture in comparison.
