John534 - that reduction gear setup looks amazing. Did you engineer and build that yourself? Or is that an add-on for warbird engines? Also, it sounds like the engine gets very quite after a certain RPM - am I imagining that, or is that some property of that engine \ muffler combo?

Very, very nice.


And the engines look good, too.

I agree very nice!  But three's a crowd!

Have the MVVS .40, .49, .91 and a boxed, new .61 (purchased from Morris Hobbies, when he was still in business!)
Great engines.

Sorry, rhk, but I won't quite believe it until I see pictures of a very attractive, well-dressed female holding those engines softly in her lovely hands, clutching them very close to her ... self ...

I have an older MVVS 40/6.5. It needs an O ring for the carb to case, and another for the throttle barrel. Anyone where I can get these? The case one I can probably subsitute something, but the barrel one looks special.

thnx

AMB

I bought a box of 225 Nitrile O rings metric at harbor freight 5 or 6 bucks and they go down pretty small might be worth a check martin

If you want a factory spare try Pe Reivers at:

www.mvvs.nl

Easy to deal with and easy to order from.

Another option is to email the spares dept. at the factory "MVVS, spol. s r.o." in Czech Republic and ask for Sabina (who communicates in excellent written engilish):

[email protected]

or Josef Å*vajda for technical queries:

[email protected]

He designed many of the engines for MVVS and works in spares I believe to this day.

Purchasing from the factory is more difficult as there are no "on line" point and click facilities.

The other day at the field I started a NIB Modela diesel for a friend. Nice runner.

Bad news:
The .15RC is discontinued, CL versions still available, so are the .15 RC and CL diesels.

Hi all,

Was wondering if anyone has any info on an MVVS .72 size engine? Was said to be forerunner of the .77 size??

Many Thanx & Happy Holidays for all

T-man49 in Alabama

pe reivers

It's one of a series of three engines:
.60, .72 and .77, all based on the same crankcase casting by using different strokes and bores. All these are strong runners at lower rpm/large props.
For detailed info, check on www.mvvs.cz or my web page www.mvvs.nl

Hi Pe, Thanx much for the quick response.

Have enjoyed your "site" with many visits.

A good new year to all

I dug out some of my other MVVS engines. Here is my MVVS 6.5cc Quickee 500 racing engine. I think they stuck on the MVVS carb intended for the 10cc engines on this one. As it has a really big bore in it in comparison to the other 6.5cc engines. But I was too lazy to measure it though.










Here is another one that I have:




You can see the smaller bore carb on this one


You can see the smaller bore on the newer model 6.5cc blue head engine here too

Hi!
John ! Do you have that reduction gear for sale?

My Feedback: (61)

I've got one of those Q500 .40's NIB, with the pipe and header, but I won't post pictures because I can't compete for backgrounds..

john534

Hello Jan,
Thanks for your interest and we are looking to have these(and other engines) available this summer or fall. I will have a thread on our reductions and a website up around the same time when.

Stay tuned, and thanks again!

Taurus Flyer

fiery, don't worry!
Here is my contribution and just as you I show my model because she is at least as important as the engine she is carrying.

"Miss Replica Top Flite Taurus". descendante of a family of fifty years ago. After the HB and the OS Max, she is most happy for several years now with the long stroke in her engine room.
Basically she is 'sized' for 0.45 so we can speak about a tight fit with that 10 CCM , see my close up photograph 2.

She did undergo some surgeries to mask her age; fuel pressure controller and Robbe Bordcomputer for datalog of fuel level, temperature, RPM.
Last pictures, "Miss Replica" with some finery, in action, photographs made to investigate the downwash. for which she also is equiped with an airspeed controller and airpeed logging.

Great looking ship!

I am sure it is more than adequately powered with the 10 ccm MVVS.

I see you run a Graupner G-Sonic prop. What is the size?

Taurus Flyer

fiery


It's a secret so don't tell other people, she is addicted to alcohol and doesn't like too much additional liquids.
So she drinks methanol diluted with 2,5 % nitro and 10 % synthetic oil.
The Graupner G sonic is a 13 x 7. she can manage these big guys!

I've always have to make her "enthousiastic" before I bring her in higher spheres. I did make a short video of that.

There are also some more "in action" video's of her but to make these we are still learning. there is a small generation gap.

Here is a little video with the Modela 2cc diesel, it is a very nice engine. Both powerful and easy to operate:

I had forgot I took some pics of my old MVVS 35cc engine. it isn't exactly a lightweight engine either.
It is a little on the heavy side with its All up weight.  I need to put this on something in the future as I remember it as being a pretty nice running engine at the time.  Beleive it or not the plane it was on was involved in a mid-air on the ground collision. Someone else lost control of their plane, it did a huge loop on take off and dived straight  into the pit area right on top of my plane. No damage to the engine of course but the plane didn't do well at all.

Oh yeah, here is my little MVVS 1.5cc diesel engine:





I found a Modella muffler that fits the engine too at Hobby Club.


I have a Modella RC carb for it too.



I have a big MVVS 10cc engine with both the glow and diesel heads:






I acquired a 2.5cc MVVS engine from Pe Reivers a couple three years ago before his supply ran out.
