Dear All
I have a request for any forum member who is a wiz with CAD.
I’ve been thinking and planning for a year or so about a project I’d like to do in retirement, still a few years off.
I have several sheets of plans for a Wittman D-12 Bonzo. It was originally built in 1934 by Steve Wittman and was a successful pylon racer. There are a couple of variants between 1937-38.
The most accurate plans I have are from the total refurbishment and rebuild from 1984. These show a very detailed drawing of all the main components, wing profile and scale.
The wing span was 17’2” , fuselage 22’ 2”on the renovation ( original dimensions ). A 1/2 scale model would be ideal.
Would anyone be willing to draw up a set of building plans, calculate the projected weight and suggest an engine size?
I would pay for the time involved. All the plans I have I would gladly copy and they would be yours to keep.I have some pictures I’ve dug off the internet and a photo of the most detailed plans. I shall post these later when I’ve reduced the size
