that is a surprise martin

they say a 6x3 or 6x4 no muffler sounds like a wimp for a 15 (maybe a typo on prop size??)
After fishing a round the site (MDS) I found a pix it is a 4 bolt head with an allen screw for compression adjustment needle in cast carb body thus c/l looks like a bolt thru nuffler most
likely the Glow muffler will fit. I would guess you would plug the holes for the needle valve anf fit an rc caaR, Odd they do not offer in RC version
Any of you guys in Europe familiar with this engine??

http://mds-engines.com/catalog/avia-01500.200

Catalog here

http://mds-engines.com/files/Katalog_Engl.pdf

These engines are indeed sold at €59. Over we we can get the pylon engine 15FS with pipe and rear exhaust for €46!
From what I am able to discern in their catalog, the engine is the same as the 15F with a diesel head. The carb from the rc version, 15FS is surely bolt-on, as is the silencer All these .15 engines seem to be plain bearing.
As for the prop range, they are using the same ones as for the glow versions, which are high-speed glows, hence the low prop width.
Postage costs should be peanuts, according to the website of the postal service they use!

Hmmmmmmmmm, very tempting indeed


Edit: added catalogue url

The first listing page allows you to pop up the specs in more detail, by clicking the small print box bottom left...

One of the two urls lists power output, which if I recall right, claims .31 horsepower (DIN or SAE?) at 14K, for the "vari-comp" - can't they say diesel? - and .36 for the shrieking glow version at 19K.

Comparison of pictures for these two look like they left the stopper in the sink for the "VC" (DIESEL! D***IT!) ...

Interesting, Thanks!

(edits - clumsy wording...)

unless i am mistaken the Enya I think was around $125 a month ago

No, the russian people does not to say "Model diesel engine", the engine in russian are called for "Kompressionovye dvigatel´" (Компрессионовые двигатель), it means compression (ignition) engine because the engine has the contrapiston who are variable and will be called for "compression ignition engine".

But you would have to add for shipping.

The specs aren't outstanding but it is a bushing engine. Who's going to be brave enough to send their credit card info to Eastern Europe?

Over here in the U.K MDS gained the reputation........ MDS... Metal Door Stop.

Some swore by them as they were very cheap, others swore at them for days on end when they would never run correctly. For a glow engine they were very cheap, and there were even some people who got one that worked, or so they reckoned.

I remember someone smashed one to pieces with a BIG hammer and posted photos of the dead engine, his patience was finally exhausted and he reckoned to save his sanity by killing the damned thing !

MDS diesels may well work.... strange things do happen !

I was feeling like buying the MDS 15 with tuned pipe I mentioned around 1 or 2 years ago, but heard that brick story about these engines
I bought my CL PAW09BR for €70 last year, although NOS from the LHS. For the same €59 I can get a Davis head for my 40LA and still buy a quarter liter of castor and 1 liter of kero for the fuel and be certain that it will run! (I need to feel brave about doing this conversion soon... )

You have written so many and so beautifully ( ) about MDS "crap" products (from your words), but only one question - personally you had experience with MDS engines? Not your neighbor/friend/grandmother, but personally you? Or you just "heard somewhere", "read somewhere"?
P.S. I can only spare "someone", who tried to repair engine with a "big hammer" instead of sending to the competent repairmen...
P.P.S. people may think independently... "strange things do happen !".

Status: offline 		Dumuk, I'm one of the guys who has good luck with MDS engines, I own about 12 of them, with two being converted to Diesel. The problem most people had was trying to run them on high nitro, they simply won't run on more than 5%, Fox engines are the same. The .78 for example ran great when you treated it like it was a .91 and ran a 14x6 on it. As a Diesel the .78 turns a 12x8 three blade at just under 9,900. The 1.48 converted to Diesel turns a 14x7 three blade at just under 9,000. The 1.48 is actually a 1.506.

This MDS looks like a nice little beginners engine for competition control line. The "allen screw" is actually a push pull head. The bulge on the bypass indicates schnurle porting and the claimed output of about 0.31BHP is equivalent to a bit less than a good stock Oliver Tiger diesel.

Not a wimpy little engine at all. Is probably superior to a CS Oliver Tiger.

The 6x3 - 6x4 isn't a cox style .049 prop but probably a relatively wide blade European F2D combat prop. The motor might be meant for some eastern european beginner c/l combat class.

Probably wouldn't convert to r/c very well at all. Why don't you buy a PAW instead.

Hi,
I could quote my own experiences, but would they be necessarily true ? I might just be biased against MDS engines. I DO like O.S, T.T, MVVS and PAW and that's for sure.

A quick search of the newsgroups associated with RC will provide any amount of comments about MDS engines. A lot of unfavourable comments and some favourable ones. There is a very broad range of satisfied/dissatisfied users comments, the balance is more dissatisfied.
There is sufficient reading to make my comments appear to be valid !

The main problem seemed to be around quality control. The MDS could be a good runner and did have plenty of power, however there were carb issues and other problems. If you got a runner it was a good cheap engine, alternatively you could get one that would never run right and was unreliable.

The main plus point for MDS was low price... for just a bit more money an engine with more consistent quality could be bought.

The guy who posted photos of the MDS engine he "killed" with a big hammer did so because he was thoroughly dissatisfied with it, why send a cheap engine in for repair when it was probably going to come back with the same problems ?

PAW diesels are easy starters, run well, attract favourable comments, have easily available spares and there are other diesels with similar attributes.

MDS have a shaky reputation, spares MAY be available, most retailers here no longer sell MDS glow engines. The MDS diesel may suffer the same fate and not be sold by major retailers for long.... who knows ?

Gee Philip, I've never seen someone admit that they couldn't fix something with that much frustration (or anger). I'm sure many of us have wanted to...but you actually did it. Cool!

...Shall we call that a Thor modification?

Status: offline 		One thing nobody mentioned was that Diesels do not have the quitting issues that glow engines have. A Diesel can be set up really poorly and still continue to run. And, for the guy who used the hammer, I'd get kicked off this site for saying what I really think, But, there is no such thing as a bad engine. They're all made out of the same stuff, have the same adjustments and each has its fuel, prop and glow plug requirements.

Pe Reivers may have a few MVVS 15Ds left or really keep it simple and get an OS15 LA easy to get and put a Davis head on it martin
some of the UK sellers may have some EnyaCX15d ??? Model Flight down under does not
The OS LA conversion is the easiest way to go

jUST LOOKED AT THE GLOW SITE AND A CHAP WAS ASKING ABOUT MDS SEVERAL REPLIES STATED POOR QC
