There is a comment that I picked up on in another thread that says that we have great choice in the sub 1 cc diesel class that are in production and was wondering how extensive that list might be?

Ones that I know of, and there are most certainly going to be others are -

MP Jet 2 models?)
Red Fin (3 models?)
PAW (3 models?)
PB 030 (still in production?)
Cox 049
PAL Lola 0.3
CS (3 models?)
Norvel?

Please feel free to correct the above and/or add to the list.

Cheers.

I think you pretty well covered it.

Norvel is now NV Engines. They do have a .049 and a .06 that fits in this category. But they have the AMD .049 and AMD .06 Control line and RC versions (Pre-Revlite designs). Then there are the Big Mig .049 and .06 engines in CL and RC. One might consider the Helihead .06 Big Mig as another engine too. They have a diesel head for them too. The Cox .049 heads work on them as do the MECOA diesel heads too.

Red Fin Engines has arguably more versions. A .030, plain bearing, .030 single bearing, .030 dual bearing (limited production), a plain bearing .049, a plain bearing .06. As well as a .030 rear valve engine and a .049 rear valve engine. They also have a .050 side valve engine (CS made) too.

PB .030, yes he still has some to sell and could make more too.

Ronald Valentine is always coming up with new tiny engines off and on too. But they seem to be more of a collector kind of thing than something that someone might use and run.

I know that Rustler Engines makes replicas as too but can't find his engine list at the moment.

I might petition Hobbsy to sticky a thread showing Diesel engine suppliers since a lot of them are very 'boutique' and hard to find without help.
Thanks Earl.

Back in the '90's there were many tiny diesels made by Arne Hende' from Sweden and VA from Russia that were imported by several sources. They turn up often on Ebay and most are still new in the box.

Here are a few pictures of some of mine.
