I was unaware of the white... I thought there was only clear. Have any on hand? I only need a little bit for these tiny decals.
Yup. You're welcome to as much as you need. Now we just need to get together again

I can now clearly see the finish line and it looks like a win.
I decided there must be some asymmetry in the construction, so planned a 42 inch version. I made this using planked construction, and decided this should have retracts, so got some small HobbyKing units and fitted them. I started again with a single motor, but got exactly the same results as the 32 inch plane.
I was a bit stumped then, so made a third one using 4mm Depron the same size as the original small one. I fitted a small indoor type brushed, geared motor, and it flew fine.
I got interested in this amazing plane in the early 2000's, but found it difficult to find any info on which to base my plan. I eventually found an A4 sized magazine three-view and drew up a plan for a "proof-of-concept" model. I started building it from light balsa sheet, purely to find out how to build such a curvacious beast. Once I had a basic shape to work with, I moulded wet balsa onto a foam blank that I'd carved and sanded. I fitted formers of the right shape inside, and it looked OK. It was only 32 inch span, but looked great. I tissue'd it and painted it Orange for visibilty.
I thought this is going to be something, so I fitted a single motor, 4 x 9gm servos and a small 3-cell pack. It went away from a hand-launch like a scalded cat, and after about 15 feet dived violently left and crashed. i repeated this several times, and decided I must try a contra-prop motor. i found a suitable sized unit, wrestled a standard spinner to fit the two props ( a bit poorly), and got the same flight characteristics.

I'll decipher that quote. I built this one as scale as possible... lemme go check the measurement.
Ok, so following the straightness of the leading edge and the trailing edge to the center line of the aircraft (red lines in the attached diagram), My recommended CG is no more than 2.7% aft of the leading edge at the centerline of the plane (Green line in the diagram).

Thanks Willsonman. You're probably aware of the latest Bugatti 100p webpage at http://bugatti100p.com/ The way this plane was designed is so surely the result of one small team, maybe one man, rather than a committtee, a bit like the Spitfire Vs the Hurricane?]
