I had been thinnking of this for some time. Wanted to document all my engines and what better place to preserve them for posterity than the RC forum.
Over a period of time I would slowly post all the engines I have or may acquire later.
Hope this would help in converting some of the electric flyer to wet fuel engines as well

So here is the largest capacity engine I have. 

1. The plain box hides a gem of an engine. The engine is considered to be must have for most of the precision scale and 1000 hrs job models where you can not afford to have the engine fail mid air
2. Its a Laser 150 four stroke manufactured in UK. The engine is not known to be a powerhouse but for reliability. In fact the mfrs themselves recommend putting a 150 where a normal 120 would be required.
3. The box on opening
4. The engine as it comes out of box. Muffler and carb are not yet attached

5. The carb, the shiny steel part goes in to the engine carb manifold. You would see that the fuel charge has to travel a very short distance and straight to the induction port
6. The muffler. The part with"o" rings goes into exhaust manifold. Advantage of this muffler being that you ca rotate it and fit it at any angle you need to. Same with the carb as well
7. The engine rear view. Push rods, rockers are all at the rear to protect in case of that unforeseen circumstances. This is same design philosphy as Enya of today and OS 4T of early years. You can also see the manifolds for carb and muffler, the carb goes on the left and muffler to the right (as lookedfrom rear). You can also see the crankcase breather at the bottom of the crankcase       
8. The engine right view

9. Front view.
10. Top view. The plug is staright up unlike the enya which are angled to the front making use of a removable booster impossible. Here one can easily use it but has to be careful.
11. Clsoe up of the crank. You would notice that the entire engine with the exception of carb and muffler are machined from bar stock and not cast. Quality is evident everywhere. All metal joints are sealed with silicone gaskets and the engine inspires confidence
12.  The supplied instructions

13. This portion shows that the mfrs recommend 15% oil content and very clealry say that no nitro is required, however if one wishes to max recomendation is 12.5%. Alsoif you notice for gen lubrication and preservation the recommendation is to use SAE 30 or 2T oil. Now that would be easy andeconomical than the prorietary after run oils
14. Prop and fuel tank size recommendations

Make this a sticky topic and others should also post interesting engines
waiting for the next engine in this series Capt. Maybe details of your RCV engine which is a totally different concept.
 does anyone have an OS wankel?

Doc,
I would prefer that if some others have interesting engines a seperate thread is started. And BTW mythread would not be limited to interesting engines alone but would cover whatever engines I have from exotic to mundane

Next in line, again from UK and a very good pedigree. But not a glow this time a diesel. Many of you may recognise the form. Yes it looks very much like our own sharma diesel (actually sharma diesels resemble these). Yes if you guessed it to be a PAW it is indeed a PAW. And I have twp of these. Intend to put them in a small control line DC 3 which I have been working on with help of some other modellers  
1. The boxes, they do come in slightly more colorful boxes than the Laser. A bright yellow (you cant miss this in your cupboard)
2. The mfrs details
3. Engine details. Mine is a 1.5 cc TBR (twin ball raced/twin ball bearings) Paw has many varities within the same displacement, but for my intended purpose these would be sufficient
4. On opening the box the engine and needle are neatly packed in poly bag and sorrounded with tissue paper padding

From the continent. A glow. Not only out of production but the company recently shut down as they could not compete with cheap chinese imports. The lineage is again superb, known for quality and craftmanship like any other German machinery, a WEBRA Speed 90. The engine is NIB and interesting feature of this engine is that it has a sliding carb rather than rotating barrel. Called Dynamix carb. Have read mixed reviews about the carb, will come to own conclusions when I finally get to run this one

If you noticed there are no holes for mounting a muffler. So this will either have to have a strap on or holes would have to be drilled and tapped to take on a muffler. Should not be a problem as there is enough material around

I am taking pictures and posting them here in the order the engines are stored in the cupboard.
Two of the Russians are out waiting to be photographed. So hold on to your horses and all would be revealed. Giggle
Pssst.... in case you did not know it is said that Ukrainians are better than Russians or Brits Wink

More shot of the dynamix carbs
This shot shows the carb fully open.
Unfortunately while I took  the engine out today I realised that the slide and throat had started to rust. So some more oil was added to the parts to keep them safe. I am going to get a tin of grease and pack the small steel parts with it so that no way these would rust. The current situation of the rust on this is not worrisome, nothing which a bit of wire brush on a dremel can not take care of

The carb half open
You should be able to get the idea, the rectangualr slide has a circular hole and it covers or opens the carb throat. The result is said to be more linear throttle response. High Speed Needle is on the left and the brass knurled knob on the right is to to adjust the slow speed needle. The threaded rod with the brass ball takes a ball link from the throttle servo. The ball is also threaded and can be moved anywhere on the threaded rod for max mechanical advantage. Not very clear in the pic is the slow speed needle which again is a hollow cylinder which moves over a needle along with the main slide to vary the fuel supply. This can be seen just below the spring laoded slow speed needle on the right
Mechanism of the carb can be seen at the pic (look at the diagram just above the left side of the carb you can clearly make out the slide and the slow speed mechanism

Since we were talking of cheap chinese imports, how about one such engine??
So here is one from China Shang or commonly known as CS engines. This one is apparently a copy of the Russian Norvel with some distinctive features of its own.
NIB CS 06 Glow RC. The engine was picked up from RCD

Some more of the CS
1. Right side view and as supplied with a piece of plastic tubing. You can also spot the single bolt which retains the muffler
2. Engines front view
3. Close up of the carb
5. Left side view with the CS and made in China marking clearly visible
6. Rear view

The all greek and latin instructions (apparently they did not intend to sell this anywhere out of mainland China, else they would have included bi-lingual instructions as well  Giggle)

Recommended prop sizes are 6x3 and with APC the claimed RPM is around 14K (not bad!!)

Three views of the engine (but dimensions are missing)

So moving back from the Mainland China to Europe. We have here an Engine which today is made by MECOA in US who bought the toolings and right for all the engines made by this original mfrs from Austria.
The original mfrs main business was making live munitions and they also diversified into model IC engines and what a line of engines they had.

So here is one from thier line up
1. A NIB HP VT 21 4 Stroke
2. Any body here knows how to translate whats there on the box?
3. Label that indicates whats inside the box. From what I have observed I have three different HP engines and all of them have same box. Only the label indicates what's there inside
4. The box on opening

The engine is supplied with lot of documents and advertisement materials.
1. One of these is full line up of HP Gold Cup engines (the other line was silver star). If you observe there are marine and car engines as well Thumbs Up
2. The engine diagram showing some of the innard parts (notice how the crank is split in this engine and you would be amazed at how the same feature also figures in one of the engines to be posted later)
3. Technical data
4. Engine as in the box and no that brass thing on top left is not an empty case it is a muffler for the engine. Now you can clearly see what the mfrs made as thier main product
