VW aero-engine on a Spectrum ?

At the Tettenhall Transport Heritage Centre we are currently overhauling and mounting a VW aero-engine on our Spectrum microlight, because we don’t have a Rotax. What we don’t know is if this has ever been done before. Anyone know ?

If Ferdinand Porsche didn’t design the Volkswagen, who did ?

Mr Porsche didn’t design it.

I suppose Mr.Porsche knew a thing or two about designing engines. Ours will be even lighter because we will be leaving out the con rods/pistons etc., and displaying them separately

I’ve had a look at the specs and there is only a 3kg difference in the dry weight according to wiki. 67 for the Rotax and 70 for the VW. Actually that information surprised me. I thought the difference was a lot more than that.

We don’t mind that, the heavier the better, we have to have an engine fitted, otherwise it’s tail heavy of course. It will actually be displayed on a three foot high stand, with the tail out over the lower level of the Heritage Centre, and the wings above head height. That way it will not take up much precious floor space.

If it hasn’t I imagine it’s because the VW engine is a heavy lump compared with a Rotax.
