Like the title says, I've got an aircraft aircooled engine for sale. I can't use it in the aeroplane I have built so it is for sale. New it would be about 10,000, if they still made them.

Franklin 4A-235, 4 cyl with dual magnetos, Marvel Schebler carb, crankshaft harmonic damper. Produces 130hp at 2800 rpm. You'd obviously need quite a big hovercraft for this unit (or, dare I say it, an Airboat?) http://s82.photobucket.com/albums/j279/foggythomas/?action=v (http://s82.photobucket.com/albums/j279/foggythomas/?action=view&current=franklinsideview.jpg) iew&current=franklinsideview.jpg

Located in Cardiff


Brand new logbook from the CAA but it is too heavy for most aircraft!

Are you "Cardiff Rob", the chap with the Fred, by any chance?

Yes, that's me.

I've given up on the idea of building that Pietenpol since I've still not even found a runway within 40 miles of me that I can use for the FRED. Guess it is the same prob for hovercraft. NIMBYs, councils, change-of-use legislation, protected species of Newts etc etc etc.

Is that Jeremy from "Scrapheap"?

How do hovercraft get on with noise legislation, BTW?

Hi Rob, yes, it is me. There are at least two other aviators on here as well, Conrad Beale and Nick Long. Mind you, the linkages between certain flying "dynasties" and hovercraft ones is exceptionally close, when you look at who's who. The other expert on that Scrapheap show, Tony Broad, is also on here. It's a small world, isn't it?

At the moment, hovercraft aren't regulated with regard to noise, but a lot of work is being done to make craft quieter. Racing craft have to pass a noise test, although it's not yet a legal requirement, just one imposed for common sense reasons. Most cruising craft builders try hard to make their craft as quiet as possible, so as not to cause nuisance.

Good luck with selling the Franklin, it would have really made our airboats go if it had been on the "heap"!

If anyone is seriously looking at noise then I can recommend John Staniar Co at Manchester for a range of stainless mesh and perforated sheet for making silencers. 40 quid per square metre. I've got some mesh from them, a pack of motorbike silencer wadding and a 3-inch dia alloy tube (x 1 metre) for my FRED silencer Mk3. Flexi joint comes from Fiat cars and is a stainless bellow affair like an old Morris Minor steering rack gaiter.

Did you see it at FFF 2006? Very quiet with version 1, better now.
