It's a 2-stroke - no suction cycle.  Although not clear, it looks like it uses "crankcase" pressure to push intake air into the cylinder via ports (the use of exhaust valves allows full control over scavenging unlike "normal" 2-strokes).  The proximity of coils, etc. to a very hot combustion chamber/piston must be a bit of an engineering challenge!

The future is electric? Free-piston engine/generator + electric motors??

1904 3115cc 16Hp

But you'ld rather have one of these wouldn't you ???

You can get 200hp from a 1 litre, 3 cylinder Ford Ecoboost engine. From the car it's 125hp. Let's not forget that's the same displacement as a 35hp Briggs.
I know it's a lot more complicated though. one day I'll have a play with one when I have the time and money.

Ref Kips quote 'How cars have progressed in recent years'
I remember the popular Ford Escort XR3i ,quoted 0-60 time of 8.5 secs, my current Landrover (Diesel)
0-60   8.7 secs !! OK may not go round corners as well!!

Interesting the thing you never see in these early films is ..... Water! Which would have made things much easier for them. I wonder how long those skirts lasted on that tarmac?

Thanks Kip. Just before I joined the HCGB, as a poor student. Watneys Red Barrel and a toasted cheese sandwich to buy at the union bar--------once per week from my £2-00 per wk spending money.

Bizzarrrrgh watching people talking (but hearing nothing) Sound was a big extra cost for cine films then.

And nearly everyone with a ciggy in their mouth.

Everyone no doubt had to smoke No.6 fags just to keep the sponsor happy.

It was Blackbushe and the grass was really thick stubble the craft seemed really high tech at the time - extraordinary. Although 50 years from now someone else will be saying the same of today!

I remember an event like that where the craft wouldn't go on the stubbly grass and could not stop on the runway tarmac but where was it? The starter with the flag looks very Christopher Cockerell but is it him? Wonderfully non health and safety everywhere you look. Love the airplanes and hovercraft moving on the same runway. Great.

Kip, you got me thinking (dillicult) about my first intro to HC. It was when I was still at school about 1967/68! Some guy had advertised a meeting and brought one along to the Kingsway Hotel in Manchester, I think he was trying to drum up some sponsorship! The HC, from memory, was similar to a Hoverhawk, would this be right for the year? (One lift and two thust "stuck" on the side)
