    It would be good to see the same used on motorbikes. We get quite a lot of them touring on the weekend. Some of them seem to think we like the sound as they gun the engines and speed away from the pub.

    Actually, there's not much evidence either way but bikes with augmented pipes have more accidents. I don't personally think it's that all that noise keeps the riders from knowing what's going on around them. Rather, it's likely that riders who like it loud are less risk averse.

    There's one non-study, no evidence article that reads like a spoof but claims that NTSB will require bikes to be louder since EVs are so dangerous to pedestrians.

    Well, OK then.

    A friend was in a Chinese city a couple of years back that only has electric scooters. He said it was eerie... and dangerous. Silent death everywhere around you.

    As for my three main bikes (the two KTMs and the Funduro), I wouldn't say that the pipes are "augmented"... just, de-restricted. I prefer augmented lighting too... LED running lights are good. Better chance of being noticed by the cagers

    There's loud and there's being a wanker, these guys are the latter. They also risk lives as it's a 50KM zone.

    Sounds like the bikie gang brigade. They risk lives by selling drugs to innocent locals... and they've managed to use the proceeds to engage a QC who won some defining case about Harley's and noise.

    Cops have been instructed to not book Harleys on noise charges, because it's a waste of police resources.... so, the real cause of the problem is the druggie locals who funded the bikies.

    Not in this case these are mostly Queenslanders out for a weekend ride. Most of them are fine but there is usually a small penis element.

    Yeah well same here but I reckon the idiot who did the big burnout take off from the pub and stacked his Harley on the bridge was really trying to compensate.

    Definite thread drift, eh?

    That's not a low pass... this is a low pass



    ... and if you insist on it being a low B-17....

    This is Don Bullock in a B-17 at Biggin Hill. He later killed himself and 6 others in a B-26 at this same spot when he botched it

    I like this one. Pulling out of a loop... scratched the paint, but didn't ding the metalwork

    Simpler is better, except when complicated looks really cool.

    What a lot of work. I'm impressed.

    Quite impressive build. But I think you're right, everything is not linear relationships in terms of scaling down. I'm thinking mostly about engine yaw moments versus tail arm and area. Also flow disturbances causing loss of lift are magnified at the smaller scale. Reynolds numbers, laminar flow, etc. It sure would be good to have a really good aeronautical engineer look at that design, if the numbers have not already been run, before first taxi and test flight.

    EDIT: Ah, old thread. Looks like it flies fine.

    Arnie Brewster hummed along with the week's number-one hit blaring from the car's hexaphonic speakers, and shouted the "Yeaaaah! Owwww!" out loud as he left the San Francisco Bay Bridge freeway at the Berkeley exit. The lines of the black, maroon-trim, General Motors Leopard were low, sleek, and curvy—contrived by its designers to convey subliminal suggestions of phallic imagery and sexual potency. The dummy air-intakes and racing exhausts carried connotations of power and strength, laced with a hint of danger; the imitation wood-grain interior paneling, and leather-scented upholstery spoke of sophistication and taste; and the dash-mounted driving compass, padded steering wheel, and authentic-looking manual gearshift projected the qualities of competence, confidence, and rugged masculinity that the General Motors' marketing psychologists had identified in the self-images of 72.3 percent of the males, aged twenty-five to forty, in the educational, occupational, and income groups at which the Leopard had been targeted.

    Actually, the engine concealed inside the shell was a low-cost, four-cylinder model imported from Taiwan, and the mounting frame a modified chassis originally developed for a brand of golf cart. But Arnie Brewster was oblivious to anything like that as he came out of the exit curve at thirty-five miles per hour to the accompaniment of synthesized wind-noise and the tire squeals injected into the sound system.
    Generation Gap, James P. Hogan

    Hope the voyage is a long one.
    May there be many a summer morning when,
    with what pleasure, what joy,
    you come into harbors seen for the first time...
