    Will - I read an article somewhere on the new TUV regs in Germany. It's not a plastic as such they're using, I understand it's resin reinforced recycled paper and cardboard being used for most interior surfaces. Including dashboards. Apparently it will decompose naturally if dumped but can be recycled.

    Sounds like a trabant body.
    Duroplast is light and strong. It is made of recycled material, cotton waste and phenol resins.
    Similar to fiberglass, Duroplast has limited possibilities for efficient disposal. As discarded Trabants began to fill junkyards, disposing of the bodies inspired creative solutions. One of these was developed by a Berlin biotechnology company, who experimented with a bacterium that would consume the body in 20 days. Urban legends, depicted in the movie Black Cat White Cat and described in a song by the Serbian band Atheist Rap, described recycling Duroplast by feeding the cars to pigs, sheep and other farm animals. In the late 1990s, the same Zwickau plant that manufactured the Trabant developed a solution for Duroplast disposal. After removing the glass, engine, and steel frame, the Duroplast shell is shredded and used as an aggregate in cement blocks for pavement construction. This was featured in an episode of the program Scientific American Frontiers on the American PBS TV channel.
    Public perception
    The use of Duroplast in Trabants and subsequent GDR jokes and mockery in western auto magazines such as Car and driver gave rise to an urban myth that the Trabant is made of corrugated cardboard

    I'm quite familiar with the Phenolic resin and fabric material used for everything from PC boards to gears (If that's what is being discussed)and have breathed quite a lot of the machining dust) but to be quite honest I don't think it is much benefit as far as keeping the world "green" is concerned!
    I think however that the phenol itself makes a good disinfectant - we used to have a product called TCP which smelt a lot like it and which we put on our gravel rash etc. when we fell off our bikes as kids! and I noticed that ants smell like it when squashed! - which maybe explains why they like to live in switches and junction boxes etc. (where they sometimes get frazzled and blow up the electronics).

    Great sound! but those things cost an arm and a leg! - you could build a complete bucket racer for the price!

    If you nose dive one of those things into the ground during a "dumb thumb" moment with your transmitter/joystick,(and I've done that) then you're up for big bikkies - the two I totalled were not quite that expensive of course.

    They do sound great though, (even if they are four strokes}.

    I remember asking Frits if he had heard of theis engine on the ESE thread years ago
    there was a 4 cylinder 125 version as well I think it was a two stroke Scotch yoke design i beilieve meant to do 16000rpm or higher with a 50HP target
    Nothing came of it, one of many English world beaters
    This is from Mike Moores Eurospares site.

    In the 1960s the English had a series of 'world beater" engines that were proposed for construction. Maj. John Treen had several interesting designs. The one he proposed for financing by a special lottery was a type of modular sleeve-valve two stroke he called the "Excalibur" (as it had an X shape to the engine). Mike Dearman has a picture of the 8 cylinder 250cc Excalibur on his site at

    That's one I've never seen before, interesting layout!

    I remember the Excalibur but have never checked out the engine construction. - I don't think it was seen much after that photo was taken.

    The picture I posted of the Redrup radial, I took a few years back in Sammy Miller's museum. One of the Treen Excalibur photos on Michael's website was from the same visit.

    Small world, i originally asked Frits about after something i read in an article by Brian Woolley that briefly mentioned it. it was either that or a letter to the editor about a brian wooley article he did for classic racer.

    The crankcase was made up from layers of half inch (I think) ali plate held together with long through studs. When I went back last year the museum had put it in some unrelated, but contemporary, cycle parts to make a period special that never really existed. They did admit to it, though...
    So, 4 cylinder 50 Bucket?

    Can't believe I missed that one way back - around that time (when 50cc racing started at IOM TT in the early sixties) I was mucking around (trying) to tune 50cc Itoms for racing I was achieving around 65 mph when the first Suzuki 50 racer was probably cracking around 100! - My 125 BSA Bantam was cracking 75 mph! when the 125 Suzukis were probably capable of up around 130 mph - but all good fun.
