Another early one from France, the famous Allouchery Eclair 1,25cc. ("Eclair" translates to "Thunderflash")
It is believed that this is the engine which "inspired" the Mills 1.3.
This particular one is an early example, probably 1946, if judged by the strange" needle valve".
It is not restrained up and down,just pushed in, and seems to control the flow of fuel from full on to full off in less than half a turn. I now understand my difficulties when I first tried to run it.
Has anyone experience of such a "needle valve"?

From Aeromodeller magazine August 1955, here are some information about modifications to the frog 50 introduced for that same year. Hope it helps figuring at least whether your friend's engine is pre- or post-1955.

Hi Olmod, Jack,
There's MkI, II and III versions of the Frog 50.
MkI has a straight needle and no extra band around the crankcase casting (I think to allow for a stronger conrod big end). Mk II got the angled needle and I think the Mk III got revised porting for a bit more power. Not sure when the band appeared, think it was MkII.
Mine is a MkI. Starts easily, runs well, but not as much power as my ED Baby or Allbon Dart which were it's main rivals at the time.

The only frog I liked was the 149 Vibramatic. The rest were not that great power wise and not easy to start at all.

Hi Vintage 1,
Couldn't agree there.
I have 4 150's, 2 MkII 100's and they all start very easily and run just great.
The 100's especially are excellent, have one in a 45" Quivver and it pulls it through BIG loops with great ease.
I do agree on the 1.49, mine runs really well and is an amazing fuel miser.
Even an old 160 red glow runs OK for me, althoiugh admittedly no powerhouse.
The only Frog I have not come to terms with is a MkI 80, the snappy little thing has drawn more blood than any other engine I own. Must be that O ring contra.

Time to wake up this most enjoyable thread.
My latest diesel powered effort is the little plane I built for a Schlosser 0.5 RC.
It’s a Vic Smeed Mamselle (rather obviously).

I test flew it between rain showers on late Saturday afternoon just after I took the photo’s (you never know about first flights!).

However all was well, it flew without any need for trim adjustments.
Had to land early on the second flight due to reducing light and increasing rain.
Very nice to have such an effective throttle.

Given my usual weight problems (16 oz was bit over my target) it glides very surprisngly well.

The Schlosser is an absolute delight. Just the right amount of really smooooth power and excellent throttling combined with 1 or 2 flick starts, who could ask for more?
It even tolerates a 5/32 brass extedned exhaust quite happily.

I have mixed my own diesel using ether stored from 20 years ago, but more recently bought diesel from a vintage combat flier in Altona (advertises in ACLN). Unfortunately the issue is transport, Perth is a long way from Melbourne so that will not help much I'm afraid.

Tell him to 'touch base' with Controline fliers for ether and IPN......They always have stocks. CL fliers seem to have all the clues on those two as they use a fair amount.
Castor is available from any chemist or buy Castol M (BP own Castrol), and Kerosene is available from any hardware store, or better still, go to an airport and get hold of JetA1.
Keep it all in dark glass bottles with a metal screw cap......as in Brandy bottles, and put away in a cool dark place.
Mix it in small quantity's as required. Too easy.
