RE: mvvs 1.60 gasser carb #'s
I answered your questions elewere. Are you cross-posting?
Heat is the only cause as far as I know. The split outer ring is a result of rollers touching the ring without an oil film supporting the load. A very typical failure mode for bearings that run either too much load, or run too hot.

RE: mvvs 1.60 gasser carb #'s
I have a Saito 180 with about 10 flights on it I am looking to sell and use the cash for cash and buy or trade for one of these engines... Seems to be the right combo for my CMP P-40 going to paint and don't want to deal with Nitro.. If you guys go to sell one of yours send me a PM.... Thanks...

RE: mvvs 1.60 gasser carb #'s
looking for some feedback on a CB Sukhoi 72" kit i'm building and thinking of installing 1.6 MVVS engine in it.
i believe the plane will come out around 11-12lbs. if all goes well. the wing area is about 950 sq" and am wondering if it's just too small of a plane for this engine. i've seen others on the web running it but don't have a lot of info with them flying it in this plane.
also, i see some are going with vibration mounts and other with the radial mount from MVVS. are the vibrations a problem in this engine?
is there any ignition shut off that comes with the engines?
thanks for any info

What kind of flight is your aim?
For 3D, weight must stay below 12 lbs with this engine on tuned pipe, below 11 lbs on canister, and below 10 lbs on pitts muffler.

RE: mvvs 1.60 gasser carb #'s
For aerobatics, the 160 gasser will be great with a pitts muffler, if not too restrictive. The Bisson works well too.
The rear radial mount is the best way. Either direct fitted to the firewall, or using through the wall iso vibration mounts. A 3-4mm (1/8") medium hard alu sheet backplate with standoffs also works well.
The engine vibrates less than a glow engine, due to controlled ignition timing. Props still need to be balanced though

RE: mvvs 1.60 gasser carb #'s
Hi, finally got to the end of reading this thread! Thnx for all the info.
Bought a second hand 1.60 red head with vlach ig. Just got it bench mounted last night so hoping to run it this w/end. It's got stock muffler for now. If it runs OK it's going in an Aeroworks Yak 72", hopefully under 10.5 lbs for IMAC.
Pe, probably gonna be in touch re muffler/pipe combinations soon, but I need to get the plane and do some measuring/thinking! It's got a fairly big cowl and a square-shaped cut-out back to the undercarriage. It looks ideal for one of the short pipe on your web site. What would be a good compromise? Need it to be quiet and broad power. A while ago there was mention of a new 4-chamber pipe, but it's gone from view at the mo. Is it still under development? would it be worth waiting for?
Anyway, this is my first gas effort, so going ot be lots of trial & error I expect!
Cheers
Simon.

Hi Simon,
i too am thinking of getting a MVVS. please post up when you have run it,etc. i'd really like to hear more about it and of course a few pics in the Yak too.
i'm still very undecided on going with this engine. mainly because the airframes that it would go in are boarderline big enough. i've been building a CB Sukhoi 72"
anyway, keep us updated on your run-in this weekend.
cheers

The 4-chamber canisters devellopment is delayed, because MTW is tied up with other work. The three chambers work so well, that the 4-chamber design has not the top priority. The 40 - 60cc tuned pipe is available though.
Large cut-outs in the cowl bottom without air extraction devices make my hair stand on end when cooling is important, like in gas engines. see my forum http://www.prme.nl/forum/ to read more.

RE: mvvs 1.60 gasser carb #'s
Thanks Pe for that, when I get going on the Yak I'll measure up the cowl etc and come back to you. Also will read your info on cooling, want to get this right!
Anyway, ran up my MVVS this weekend and all was good! It was a bit reluctant to get going at first, been stored a while I think. Now starts from hot on 1 flip. don't have an tach at the mo but seemed like it was pulling well, lovely sound.

kochj,
yes, 11+lbs seem too heavy, but it has a big wing and flies light - it's a larger plane than the Funtana 100. Mine has 12.74lbs and I did a lot to keep it light. There is a lot of 3D in this plane. Hover is not everything for me, but it does it too. No unlimited vertical though.
The pipetunnel is not long enough. I used the supplied glasstunnel for the rear and made a balsatunnel up front. This plane flies so good, that every time out at the field I get offers to sell it.

The thing is that I fly electric so I have to convert most of my bigger planes. However I'm having a REALLY difficult time even finding a build thread (never mind conversion threads!) on any of the message boards online for this plane. These kinds of threads help immensely in determining the pros and cons of an electric conversion of any particular plane.
So ... would you know of any such conversion threads or even just a regular build thread? If you know of any I'd really appreciate those links.
Now since you have one maybe you could help me out with some stats? Stuff like:What's the wing area?
What's the weight of JUST the kit parts?
What's the suggested flying weight?
Also what are the flying characteristics like ... 3D capabilities? How about comparisons to the other popular aerobats in this size class? (Yaks, Extras, Edges etc)
My apologies for all these questions but I've been desperate to find ANY info on this plane. [:@]
Thanks!
Colin.

RE: mvvs 1.60 gasser carb #'s
Hi Just an update on my MVVS 26 - I maidened my Yak with it last weekend (see http://www.rcuniverse.com/forum/m_40...43/key_/tm.htm) and it was fab.
Pe, do you know where I can get a plug spanner from? Standard sockets don't seem to fit as the ring as the ring around the plug gets in the way.
Thanks

Yes,
Evolution also has the slanted look now..
Horrizon has them advertised but not in stock yet....
Surprised that they updated ONLY the plug angle????
Why not some way of performance? or lightening?
At least with there 35cc engine!.... That is in need of some MAJor weight loss!...
Not a bad engine have you, it has the potential to be Very very popular, only if, they reduced it's weight!....
I know the Sundowner racers, would GREATLY appreciate that!...

Also,
If you don't mind the old style head, You can save yourself over 50$ if you buy the curent version!.....
(I guess they also have a quick release carb choke addition?)
ANyway, 50$ is still 50$ worth of gas, anyway!..... That could be a years flying worth in my opinion!....

The big difference is the new con rod, more durable. The old one was recommended to be changed every 30 hours or so to be safe. The new motor has an enlarged bottom end.

You can back order at Horizon or you could get one from Pe' at http://www.mvvs.nl
He is very nice and has been a huge help to many in the hobby. Horizon's prices are so high Pe' is still competitive even with shipping costs and lousy dollar to Euro conversion. A couple years ago it was cheaper to purchase from Europe.

Good to know!...
Perhaps the 35 will get an Update as well!......
Advantage hobby has awsome prices on ALL engines!....
Evolution Saito ect!....
Save over 20$ plus free shipping!....

RE: mvvs 1.60 gasser carb #'s
I finally just looked at Pe Reivers web page.....
Looks like they have added a hole slew of engines..... 50, 80, 152cc...... Interesting....
I would have thought they would have used the Magnesium case of the 45 and enlarged it to a 50cc? perhaps the structure support wasn't there to do so???
ANyway.... Nice engines....
Looks like the weight loss of the 35gt was due mainly to the increased bore...... Not really any major redesign efficiency..... Kind of dissapointing..../

RE: mvvs 1.60 gasser
OK guys, generally loving my MVVS 1.60, but having trouble getting it to 'self prime' on the first start of the day. I have taken to blowing into the tank vent tube to push some fuel through, then flicking on choke till it starts. Then choke off, flick & go. Any ideas on a better way of priming as I feel stupid having to do the above!!

RE: mvvs 1.60 gasser
I'm looking for the same answer. The carb doesn't draw the fuel till the fuel gets into it. Looks like the fuel pump doesn't work when it's dry. This is the only engine I have that kind of issue. If the plane is not flying for a week, it takes 20 minutes of all kind of tricks to get the fuel finally to the carburetor. After that the engine starts easy every time - till the next weekend.[:'(]
