Again a happy 2012 to all, just reflecting on our favorite power plants, we are lucky to have out there a few that care and take pride in a quality products Besides Davis ,we of course have Dr Diesel Clutton (PAW) here and in the land of Oz, Owen and Burford, Japan Ken Enya, and a very limited number of Schlossers a work
or art from Germany as long as these folks are around diesel will not be dead, Its really too bad that more of our of our flying Buds are not aware of the "diesel
advantage" not repeating them, we all know them again the best to all in 2012 martin

The same to you and yours Martin, I am a solidly sold Diesel nut and have been for 20 years. I still have the Fox .74 I started out with and about 20 more.

Diesel Die-hard

Yup, diesel forever! I've been a dieseller by preferencesince 1959, and have never fouind any reason to change my views. I still have some of those original diesels from 50 years ago too! Although I will admit to usingglow-plug engines in certain applications, I remain a diesel die-hard through and through! All the very best for 2012 to all of my fellow diesel users out there!

Happy 2012 to all! Unfortunately it's not all good news on the diesel front. Benno Schlosser produced his final engines last year, and 2011 also saw the sad announcement that Rothwell production will be ending. Both the Schlossers and the Rothwells were the very pinnacles of their type, and it is a shame there will be no more.

On the plus side, pretty much everything that's still being made is of excellent quality, be it the limited editions of people like Dave Owen, or production engines from the likes of Enya. One that Martin forgot to mention is MP Jet. Their 'Classic' series has a deservedly high reputation, and for something a bit livelier, the 061BB is back in production. I've been messing around with one for the last few months and it is a terrific little thing. Oh, and there's also the Ridley Olivers over in the UK, so there's certainly enough to keep us diesel fans happy for a while yet.

Cheers

STEVE 111 for me being a little on the lazy side easier, just a needle and compression screw , fuel, flip,go no glowplugs ( which one for what fuel) changing head shims, a multitude of glow fuels, extra batteries, electric a hassle which battery, balanced chargers . esc' selection?? it goes on and gave it a try now all that stuff sits in drawer
and yes forgot the MP 061, Davis got me into Cox my medallion 049 with his head great, martin


the tiger 400 did not live long as an electric, new firewall mount OS10LA davis head, dural landing gear to replace the thin wire one and I spent bucks on the brushless motor esc and lipo battery

I'm new to Diesels but I'm sure having fun with mine. For the models that I intend to use them in they're like a super light weight four stroke, less expensive as well.

AMB

BROKENWINGS very good analogy , thought I was the only one with that thought the 4 strk characteristics seem to have more in common with diesels than their 2 strk glow brothers and my style and planes the engines are running 8k to 10K both quiet and torque for the prop load
. martin
an other stunt I do with the 4 strk glow is run a small bit of diesel fuel thru it after flying (glow plug attached of course) to wash all the glow fuel
no nitro or alcohol left in the engine or bearings, the Kero is a great anti rust factor, have NEVER had a corroded bearing with this stunt

looking at one of my OS instruction sheets they had a statement to rinse the engine with KEROSENE before storing martin

AND WELCOME TO DIESEL WORLD MUCH LESS HASSLE AS STATED BEFORE FUEL FLIP-GO THATS IT

Another thing that I find interesting is the difference in Price.

Looking through *bay, the price of a diesel engine is considerably higher than the price of a glow engine of equal size.

I guess it's collector value.

You would think that O.S. or one of the other manufactures would take notice and offer up a couple diesel engines.

DeviousDave

It's more than collector value, it's choice and availability. There are a lot more options when looking for a glow .40 than a diesel .40.

AMB

Devious Dave Yes there is a large choice, I would not be surprised if OS entered the diesel market they have a lot of competition from , well magnum comes to mind in the glow field, if they did one they would get a good price for it and it would sell in spite of price, no still a smaller market but they would capture the factory issues in this range a head and carb change not a big issue
The other side of the coin they certainly are aware that Davis makes heads for many of their engines and may just let it slide, So if you want an OS diesel you have one with a simple head change, ditto with Supre tiger martin

What diesel market? It took OS 5-7 years longer than I expected to jump into the exploding gasoline engine market were there is profit and much activity. It also took them that long to get into electric motors which would appear to be completely against the grain of their mission.

We have to be realistic. Any new diesels will come from boutique manufacturers who cater to tiny niche markets.

AMB

gkamysz Happy new year good point MVVS and MP jumped into the electric market also, most likely some the best out there, but up against dozens of others and they are lot less expensive than theirs
It appears they are re-entering the IC market slowly MP jet 061BB on the way back for one abeit about 6 months out martin
OS will sell a lot of electric guess covering all the bases its $$$

earlwb

OS once upon a time did dabble some with model diesel engines. But it was short lived. It didn't sell well, so they quit. OS tends to only want to manufacture something that can be done on a large scale and sold worldwide. Thus the market for model diesel engines is too small for them to want to bother with it.

Enya on the other hand started making model diesel engines way back in 1956 and still makes some today too.

AMB

Ok diesel gurus is the MPjet 061 the same as glow except for the diesel head?? on my mvvs 15 instruction sheet the pix and parts breakdown
look the same except for heads, and cylinder/piston assemblies ( parts numbers of listed for both same sheet) martin

they have an exploded view of the engine showing all of them

gkamysz

My Feedback: (19)

No, both the MPJet and MVVS use iron steel piston and liner with the contra piston in the liner.

Ok guys MVVS engine parts glow and diesel

whoops wrong upload will try again now we got by the way its a great skin cream

and magic here is the MVVS sheet

I have both engines apart on my bench if a picture is preferable.

AMB

Greg great go for it we would all like to see I am sure, I only have the diesel martin

Diesel Fan

Perhaps in some countires where all forms of alcohol (of which methonal is) is banned?

If these countries (through religious beliefs or what ever causes these bans) take a liking to model aircraft, would you think that a market would be there?

steve111

AFAIK the MP Jet 061BB glow and diesel engines are the same except for the head. I only have the diesel - should get the glow as well by way of comparison, but the diesel is such a cracking little engine (better on a 7x3 than my Norvel 074 glow) that I haven't felt the need.

Well gents, the state of my Diesel state is about to change, I ordered a new ring for my old SuperTigre 4500 and my even older Webra .91. I have a new piston, liner and ring in the Webra but after nearly a gallon of fuel it has next to no compression. I pulled the piston out today and as Frank Bowman suggested the ring doesn't contact the cylinder all the way around. There are even streaks on the cylinder where the ring touches and does not touch with matching places on the ring. If the Bowman ring improves the 4500 and the .91 like it did my SuperTigre 3000 it will be money well spent. The Webra and the 4500 will both become Diesels when the new rings are seated.

It was a major disappointment in terms of performance in an era when Diesel was king everywhere else except the US.

The OS15D had some interesting innovations for a diesel mostly in the upper cylinder. It was the only production diesel with a baffled piston.

Surprisingly there are about 3-4 of these engines owned by members of my club, and I saw one run a few years ago. It was no-where as good as the Enya 15D, which it's self was a commercial failure.

Neither could match the Oliver Tiger.

Bye the way, the Eastern Europeans and the Russians are producing some marvelous 2.5cc diesel engines.

Diesels will never be popular again, the need for Ether will always make them a specialist interest only, and lets face it diesel conversions are just a novelty.

These big engines would perform just as well left as glows.

Glow fuel is cheaper as well.

Will you be having a "going all electric" sale soon?

Have any "novelty" or "unpopular" items?

AMB

LOCKTITE 401 MY THOUGHT on conversions being a novelty the Irvine Q40 glow and irvine 40D were the same engine except for the head
and carb I have both and the Q40 has an irvine diesel head they got mixed on the shelf cannot tell them apart they both have the 46 crank
mufflers are identical except on to 40D the pressure fitting has a plug
If has a diesel head (any engine) runs on diesel fuel its a diesel regardless of the base engine just my thoughts
if it quacks like a duck waddles like a duck its a duck martin
