MVVS engines

[Steve Kientz]

 Does anyone have any experience with MVVS engines. LHS has a .21 in stock ,thought it might be good for a smaller plane?

thanks
Steve

Steve - quite a while back, the MVVS engines were used for stunt.

Josef Gabris used one in the Super Master - winning the Criterion of Aces as I recall.

I have a few of the newer ones and they seem to be built as more of a high end, high revving powerplant.

There may, however, be some procedures that are used to adapt them to stunt.

I have a couple of .10 R/C engines.  I like them very much.  Mine are diesels, the start and run very well.

Waaaay back in 1969 at the Philly nats....I traded an OSMax 35  for a .35 MVVS a very similar one that was used in Surotkin's (spellingsic) mono wheel stunter that used only an outter wing skid...and a tail wheel. I flew it for a while in my old StingRay.

 This engine was not brand new and had been restricted quite drastically for stunt. Perhaps this is why it ran very steady...EZ to start...seem to run forever on a 4 ounce tank. However after changing to a larger intake restrictor..and a different needle valve. This old smoooothie turned into a cranky-nasty little engine...that would REALLY UNLOAD AND SPEED UP in multi-loops. But after going back to the original restrictor and needle valve.....It calmed down and acted like a stunt engine again.

Bottom line: I finally gave it away to one of my engine collector nutski's. for a bottle of Ripple wine. (that is another sad story)

 APPLES AND ORANGES..ARE NEVER CREATED EQUAL..AND NEITHER ARE STUNT ENGINES.
That MVVS weighed a tad more than the OS 35 but didn't have as much usual power...and wasn't as easy starting as the OS.
With that in mind.....Perhaps that RIPPLE WINE trade might have not been so bad after all..especially when someone realllly special helped me drink that wine later that night.

This isn't the engine...but it looked very very much like this one???

There was a specific MVVS 35 (5.6??) that was made basically from a MVVS rear rotor racing engine which was very hot.  25 of these "Stunt rear rotor" engines were made and dispersed to the Soviet stunt team.  Sirotkin used one in his WC Space Hound, and ran a 10-4 prop at high rpm.   This was in the 1964 time frame.  Now where have we heard the "High RPM, Low Pitch" deal??  BTW: in 1962 at the WC he was running on a bladder!

Ain't nothing new under the sun is there?? 

I tried for many years to find one of the RI 5.6 MVVS, but no luck.  Maybe because there were only 25 of them made??  Peter Chinn did an engine report on one he obtained in about 1966.  A version for R/C did come out that was RI and *looked* the same........ haven't got one of them yet, either! 

Ihave, however got an Akrobat 42 which is what the Soviet team used in the end of the '60s.  Runs suprisingly like a ST 46!  I will have to see how it hauls my Master (not Supermaster!).

I have two of the .49 stunt engines . One set up for alky and oil only and the other for USA nitro style fuel. I will be putting the latter in a Whitely Shoestring with a mini pipe. Supposed to pull like a mule! I hope to find out latter this summer.

Bob,

He also won the 66 and 68 World Championships with the Super Master.  A feat that i'm sure Igor would
love to duplicate!  How are you liking your new digs in SC?  The south's pretty neat huh?  Especially when
you get neat planes landing in your back yard!!  Oh, yeah, a lot less snow too!

Thanks Bill for the clarification...I couldn't think of that engine comparison size in Russki lingo and also thanks for the spullin' erroreeo' on Sirotkin!
Bill...do you have any idea where we can find that famous photo shot of Bob Gialdini and Sirotkin ,taken together, holding their "world champion battle-axes" above their heads. What a great archival photo from stunt history past. That photo of that MVVS I posted was similar but the head was different..but the intake was in the same place? Since I had no instructional info on that engine, I have NO IDEA exactly what or where that old Russian engine came from

Yes, exactly, we flew Supermaster many years aftre look at http://www.controlline.sk/oldweb/foto/memorial/master.jpg

1958 on Expo he flew "Master" the predecessor of supermaster.

But to the question, MVVS are relatively strong hi power hi rev engines, they typically need some kind of "blueprinting" like adjusting proper compression, proper installation of ball bearing and so.

Typically those engines made bigger bore in smaller cast like 4ccm in 3.5ccm case or 8ccm in 6.5 case or 15ccm in 10ccm case are for stunt better than those originals for R/C or even racing. It is because limited crossection of ports limits hi rev power little bit and gives better stunt run.

But just for record - we fly PAs, Jetts and Os maxes in contest models.

Thanks Igor for your input. I have always enjoyed reading about those beautifully unique Russian stunter  during the mid 60 through 70's.
If you have anything on that "Space Hound" or photos...to share! WOW THAT WOULD REALLY BE GREAT!
Igor...I really have enjoyed reading your posts about your electrics etc. Thanks for all your contributions over the years.

Don, just to be sure - we are Slovak. Slovakia is part of former Czechoslovakia. I am Slovak, Gbaris was Slovak, MVVS engines are made in Czech. We are also NOT Slovenia - that is another typical mistake. I am writing that against possible mistake between us, Russia and Slovenia.


But to the point, there are still differences in used models. Now we fly typically "Max" - that is model very close to old Supermaster, but usage of pipes and new knowledge of aerodynamics needed something new:

Actual typical model from ukraine looks like this:

And after all here is Russian model:

But to your question:
On http://www.vicstunt.com/ page you can find many pictures from all WC in past. I found some which could be important for you:

Jozef gabris with his Supermaster:

and something from former CCCP (UdSSR):

Shultzie, my man, I have a Spacehound I built and used the color scheme of Juri Sirotkin's that plane won the '64 WC down to the lettering (except for my AMA number! LOL!!) but I don't have a picture......... guess I'll need to take one!

I also have parts cut to build Josef Gabris' "MASTER" which he used to win the "Criteriun de Aces" with in 1958.  It doesn't share any of the features "looks wise" with the Supermaster.  It was a fairly large plane for that MVVS 5.6.

The Ilushyn is an elliptical plan form bicycle LG model that used the Akrobat 42. He flew it at the 1969 Soviet Nationals.  Gonna build it with an Akrobat 42 and have a unique Classic entry.  There was one of these built, but I cannot remember who wrote me about his. ??

The SpaceHound is a largeish, deep belly plane with a thin airfoil and a tiny tail section.  It does outstanding round maneuvers, but lacks a "snappy" corner (Gialdini term??).  Mine flys very solid, but soft corners hurt it in the AMA pattern!

Igor.. THANKS FOR THOSE AWESOME HISTORICAL LINKS:
THANKS FOR THE CLARIFICATIONS about your history. Wow! So much has changed since those early Iron curtain days...and we were so fortunate to have the FAI world championships that help break down borders and let so many of us get together to enjoy our mutual passions in modeling and sports.
Jim and Bill...
Thanks for sharing your stories about Juri's SpaceHound and those amazingly unique models of 30 years ago.

I found a rough draft drawing of the SpaceHound. Interesting model huh? This still doesn't seem quite like the model that Juri was holding up next to Bob Gialdini in that ICONic' photo from the past at the World Championships.
