Kiwi/Nev I bet, those links I found took me on a journey to some of the most exotic and expensive , jewel like engines I ever saw - a 5 cylinder radial diesel for instance I'm still trying to work out how you would set it all running perfect.
The first Taifun I ever saw was on E bay about 7 years ago and I was amazed by the streamlined shape and iridescent pale blue anodizing. My first thought was of Art Nuvo design.

Blackfoot, I think this is exactly what started the problem with my Dart.
These engines were all factory test run, to establish the correct comp.lever setting with a specific prop (as a help for beginners).
Meaning that all the NIB engines are gummed up with old castor oil !
Obviously I failed to clean the small end thourougly before I started to use the engine. In case of the Merlin all turned out just fine.
My Dart No2, as well as the Spitfire and Sabre are still unrun, and still gummed up from the factory run....I have to be careful here....

Probably this was common practise for all Davies-Charlton engines.
(assuming, without actually knowing..)

Also, when purchasing some ED-engines, later versions, directly from the (then) still existing Electronic Development Ltd, they were all factory test-run, pre-set, and subsequently gummed up at arrival. Apart from the DC's, these engines were also quite oily externally, sticking to their plastic bags... Beeing BB engines, de-gumming and cleaning was a somewhat more demanding task on these.

Heinz, what a beauty !! The "Ollie" is one of the undisputable kings of diesels (there are a few, topping the list...)
Nice photos..!

Seeing this thread reminded me I had a couple of old diesels in the loft, sadly when I went to look around I could only find one! My little Merlin is AWOL

The one I did find was this little PAW 149 RC with a lovely little silencer. I remember using it in a Keil Kraft Phantom CL at some point with some wire to rig the throttle. The needle valve assembly looks a little bent and a screw is missing from the head but it still turns over. I ought to spend a bit of time with it and get it working again.

rk295, your PAW 149 brings out some memories.... ....I have a similar plain bearing (iron bushed) 149 RC with lots of runtime...

Initially it spent quite a few hours in the nose of a 2M glider, a Blue Phoenix.
I fitted an extra silencer, silver soldered of thin brass sheet, aft of the ordinary one, and I've heard electric motors noisier than this one.
This was the model that once made a dive and dissapeared behind the trees quite far away, after losing the radio contact. I switched off the transmitter, put it on the ground and started walking in the direction of where I last saw the plane. After 10 steps or so, the Phoenix suddenly appeared again over the trees, in a steep climb.. ...running back to the transmitter, switching it on, I had contact again and was able to fly her home with shaking knees... ...I beleive this will only happen once in a lifetime...

Next model for the PAW was a home designed cabin model, 54" span, with side mounted engine. I think it weighed just below 1 kg (no micro rc-gear available by then...). It was a very good flyer, yellow/red with wheel spats....memories...

This is a good engine, rk295...find the missing bolt and make a "project".....

With some luck, even your Merlin may materialize when you least expect it...

>find the missing bolt and make a "project".....

Definitely! A missing bolt reminds me of a contest when a New York flyer (now, sadly. deceased) and I were both flying PAW 1.5 models in a contest. He lost a head bolt from his on a check flight so we made our flights alternately, swapping a bolt from my engine to his .. and back again ... and to his ... and so on.

Thanks Airboatflyingshp for bring these jems to view. All I can say is “wow” . These are all works of art. Like a kid in a candy store, I want one and that other one, etc…

Here are some of the custom made Valentine Cox 15 diesel engines that have been modified over the years.

Gluehand and Applehoney you are both correct. I think I'll keep it out rather than return it to the loft, that way I'll feel guilty that it isnt in a airframe whenever I see it

After the piper is done I'll try to find it a proper home.

Our local club arranged a meeting on the theme "C/L & Vintage" taking place today.

Not too crowded, but weather was fine.
Among many impressions, I had the pleasure to hear a Rivers 1.5 cc singing in a superbly built T/R model...also, there were a Corda Powerhouse, Slicker 50, Viking (a Swedish "all time great" from 1956), etc flown.

Worth attention was a very nicely built and well flown Monocoupe, about 40-42" span, built from an old Aeromodeller plan, powered by a throttled Webra 1.5 cc diesel.

A lot of old and/or interesting engines were displayed. The most spectacular test run was that of a Dynajet , that almost teared our ears off...

So, where are all photos, you may ask.....unfortunately the battery of my camera was a bit tired, but I managed to take a few pics before it definitely said good night....

Great pictures and old engines. Any more information on them. they look to be 0.02 cubin or less.
