I'm not quite sure what you are after here, but the MVVS are not made anymore and Fox does not make any diesels...

You seem to have forgotten Enya diesels that are still being made (in Japan)?

Mr Cox yes an oversite, have the Enya CX11D and 25D, PeRievers still lists the MVVS but these may be only remaining stock, Having MVVS15(3) and a 40 and 61 the 40 and 61 have Davis heads as a matter of fact I cranked up one of the MVVS15s yesterday 9200 on a black 10: MAS , the numbers are worn off so cannot read the pitch think either a 5 or 6 pitch fuel Davis ABC, started right up on last compression running setting
Davis makes a head for the Fox 15BB. also the quality issue on some of the imports is the same glow or diesel. That was my point of course there are quaility engines made in the Far East, OS and Thunder tiger martin

I have just ordered a P&L set for my MVVS .15D plus a couple of carbs for larger (8cc and 10 cc) MVVS gl*w based engines from Pe Reivers, so spares supply seems good at this stage for MVVS. Also, MVVS still make quality spark ignition engines in sizes 26 cc and above for distrubution under the EVO label in the US, so I don't think they will be getting out of IC engines anytime soon (at least, I hope so).

I do hope they do limited runs of their wonderful small diesels from time to time, the way MPJet appears to with their classic .040. Again, if market demand is there, it could happen. Time will tell.

Right now on the little ones Ive really gotten into th 049 Coxs , my 049 medallion I can easily hand flip to start ( davis diesel head) have the 049 baby bee and 049 sure start
(davis heads) Had zero experience with cox ( hard to believe the whole world did) after much prodding from Bob Davis gave it a shot now hooked, perfect for some small electric ARF conversions




.

Fiery, if there were a carb equal to the Irvine Jetstream it would be the MVVS carbs. I have about 4 of the 7mm carbs for Diesel use. In a bit of irony, here is a Fox .50 wearing an Irvine Jetstream and a Webra .50 wearing the MVVS 7mm carb, go figure.

HOBBSY You did it again one up on me, Webra 50 nice whats does she turn and on what prop?? martin

Here are two more .50 sized engines, I received the heads for my Webra .50 and Fox .46 ABC yesterday as posted in another post. The Webra turns the Graupner 12x7 at 9,950, it turned it at 9,570 with its stock muffler and 9,950 when I put the Bisson Pitts muffler you see on it.
The Fox .46 turns the Graupner 12x7 at 8.590.
Webra .50/stock muffler====9,570
Webra .50/Bisson Pitts=====9,950.

Here you go.

Hobbsy will have to pick up a graupner 12x7 and see what my Irvine 53 Davis conversion turns on it, maybe you have already done it ??? martin

Yep, it is the king of the .50 Diesels turning the Graupner 12x7 at 10,200, I suspect the .53 is a 12x8 engine.

Martin, note the barrel retaining screw on the MVVS carb and how close the carb is on the Fox .50, I tried to put one of the MVVS carbs on the Fox but no go.
