This is incorrect; they are perhaps the best we have without a tunnel or CFD. Just one caution is comparing one bike with another. The high rolling resistance of motorbike tyres, transmissions, brake drag, etc. means the differences between bikes can easily distort the results. Very good if you can use the same bike each time and you allow for things like wind speed and direction, which is what Bob suggested in the first place. Arthur. ------------------------ Yahoo!

In the case of wings they were originally trying to stop them falling off by banning high wing struts (Both Lotus lost their wings and crashed in the same place on successive laps, Barcelona, 1970) and then trying to stop the cars going so fast. This latter was the historic mistake of that generation (1980-2000) They reduced the size and effectiveness of the wings. The engineers, naturally, came up with more download from less wing, although it was more critical aerodynamically. This process continued untill the wings were so critcal they didn't work when following another car, making overtaking almost impossible - and quite possibly leading to some high profile fatalities. The FIA should have imposed a minimum wing area and a minimum angle of attack, providing grossly excessive download. The engineers would then have made the wings less critical, to reduce drag, and they would have been able to follow other cars more closely and even overtake. So it goes. In the '70s sponsors were quite unfazed by novelty, they just wanted their name on the winning thing whatever it was. Had to be well-polished though. Shiny wheels were very popular Royce ------------------------ Yahoo! Groups Sponsor --------------------~--> Get to your groups with one click.

The skeleton was made with lofted cross sections in 3 planes, so only flat pieces. Covered with parcel tape so far. I am going to try a papier mache shell to check the fit before I spend real money and too much time on a shape. Since the shape is modelled in 3D CAD, it can be reproduced pretty much exactly, so any clearance or fit issues can be sorted out before I spend the money on machined moulds. Or I might mould the thing directly over the paper shell. The head fairing mould on the GPZFF was made from the same type of material, but planked, carvel style with thinner Corriboard which allowed some bending. As you correctly observe, it creases easily along its length. I moulded the fairing in GRP polyester over the outside, with light weight filler to smooth it off. This is not really good enough, as first it is a lot of work to smooth off, and second ends up being too heavy. Moulding over the male is OK though, as long as the male plug is reasonably smooth to begin with. This is what Ian Pegram did with the latest Genesis. Arthur. ------------------------ Yahoo!

Some would probably put a lot of our own time and some of our own money into building them - so what is wrong (in principle) in directly funding something like this It just goes against the grain -but like I say - you can't blame him for offering.
