Toyota does not sell the leaf spring spacers ("silencers" as they call them) as a separate part, despite the fact that it is a wear item. Kanata Toyota also allowed a worn suspension component, among ...

Why not press between two borosilicate glass sheets? It would make release easier, and you could use a spacer (feeler gauges because gauge blocks are expensive) to get an exact and reproducible sheet ...

Well, it's alive. It flies great, I like the lift profile, and as expected with the higher aspect ratio and thinner profile, it stalls _hard_. Foils need anhedral - it's really hard work whipping a...
