Gee Al that was good. I feature @4.56 ish in red Kestrel GT 503 (courtesy of Mr Kip). with matching red over alls for that extra smooth look. NEVER let me down. Keith Oakleys "Spirit of Snodland" (if my memories apply),which I gather is STILL working now, and it was old in 1979!! :D

Fame at last Nick :D

Pauls union jack craft I believe had one of the earlier small ducts on which SURE hovered well, just like Dave Ibbotsons. Mine was the larger quieter duct, (perhaps more thrust) but never quite hovered on her tips. Perhaps I weighed too much? ;)
I used to polish her at week ends. Sad? Certainly not, as it made me (and my neighbours) smile. :D

Tapered duct was simply outer thin skin joining the  frd outer flared bell mouth with the trailing duct edge. (standard on Kestrels.) Nice one Kip. I "hid" my fire ext within this void on my cruiser. My claim to winning was simply it never ceased. In those days not stopping meant you were likely "to Podium". tho it wasnt a verb in those days, more a thing you sat on first thing in the morning,,,

Some of the craft seemed to have a tapered thrust duct, or was it a duct cover.  Would a tapered thrust duct increase thust or reduce it?
 
Would a tapered duct increase noise?

Al,
That sure did bring back some memories for me.
I believe that I saw a certain Mr Flint out there along with his bosom pal Dave Ibbotson.
I was particularly delighted to see my Paul, Union Jack Kestrel No 130.
Paul went on to be F1 Champion for 7 years on the trot.
The No 1 man!!
The little feller with the "anti plough" was Phil Alderman who for 5 years was unbeatable in F3.
Great Guy.
 
Note the dominance of twin ducts,and even a triple which I believe was driven by Nigel Beale.
 
I wonder who the baby faced kid was standing next to Roy Smart at the briefing? :P
Roy actually quit a 3 hour race due to financial reasons having bust about 3 sets of blades.
I think he ran out of cash for the day.
In those days if you stayed over hump and didn't bust any blades you stood a good chance of being on the podium.
 
Stanford Hall was generally accepted as being the best Racing site we ever used.
Though for me the best race of the season was the Sunday morning marathon race at Mere Brow.
 
Good Days.
 
Kip

This should bring back some memories for some of you.
 
I like the anti plough device about a minute into the video :D

Surely it's only a matter of time before two strokes are banned or totally out of production anyway (except in the third world maybe).


2 strokes have even been dropped from the MotoGP classes for a couple of years now

I agree, but development could have evolved the ideal racing engine, but nooooooo, let's go back to using an obsolete 503.


Tony Goldney proved that four strokes could win championships. Imagine if tuned Briggs 35s could have been made reliable.
Maybe the FF Rampage engine could be allowed into F50 one day (NOT F503). It would be amazing to see an affordable 50hp four stroke out there.
