I really look forward to seeing this, I built a Wittman Buster formula one racer years back. It flew well, but was oh so hard to land due to the uc being way far forward of the leading edge. I more or less tamed it by having lots of toe out on the u.c. and by landing as slow as possible, tailwheel first. The original is in the Smithsonian. Steve Wittman was evidently quite a remarkable character.

Slow progress. I've had the plans increased to 1/3 scale. 88" long fuselage, I will probably split the fuse behind the cockpit.

The wing panels are 30" wide. This is to scale though I expect to slightly increase the span by a little.....not by much.This will lessen the wing loading.

Does this have anything to do with the Bonzo Dog Doh-Dah Band?

No, Steve ( real name Sylvester) Wittman named most of his planes after cartoon characters in the 30’s and 40’s.

All the ribs are identical, thank goodness. I’ve asked Tina at Slec.

There was also a kind gent from the LMA who has drawn the wing in CAD and has done me proud.

Ha ha! I was being a tad facetious, since your original link from 2011 is dead, so I had no idea what the Bonzo was. By luck, I was not that far out from Bonzo the dog smiley. Anyway, I hope you make some progress.

It’s my retirement project. And there’s at least 5 years before I, hopefully, go semi at 60.

The young lad , Brian,(only in his 80’s who’s building a 100” DB Giant Mannock ) and I have discussed how to build it. He suggests building the formers with square spruce with diagonal members and gluing brace plates either side of all the joint. It should keep it light and strong. Then, lay down the upper most fuselage side stringer and build it up side down, slotting the formers over the plan....sounds good to me. Split the fuselage just behind the cockpit.

A forum member I’ve been in contact with in the US started doing a 1/3 scale but that seems to have fizzled out

Looks like a great subject, very distinctive. Roll on retirement!
