;)AHHHHHHH A STRING OF STATEMENTS WHERE PEOPLE ACTUALLY KNOW WHAT THEY ARE TALKING ABOUT.

RE: evolution engines?
 

Here's my .02 cents worth. Keep in mind I'm a natural born cynic (and an aerospace engineer) so you've been warned.

To say that Evo's are just rebadged MVVS's is incorrect in my opinion. The gas Evolution engines are simply reverse engineered versions of MVVS engines. While they are obviously designed to the same configuration, a side by side bench top inspection would most likely yield large differences in casting quality, machine finish, and metallurgy. This obviously effects power output, longevity, and reliability.

The Evo's are probably made in China who are the experts at reverse engineering. Keep in mind they can't manage to make dog food that won't kill animals and your children just might be sucking on a lead toy right now. If it sounds like I'm frusturated about this, its because I am. Evo has stood on the backs of MVVS and copied their engines and is now selling it with reduced quality and larger profit margins. This undervalues MVVS engines and stereotypes them as junk engines as well. If it looks like an MVVS, sounds like an MVVS, it does not mean its an MVVS.

Also notice there are no more USA distributors for MVVS--this is basically a marketing blackout to push Evo gas engines on the sheeple that think they're the same engines. Its certainly not a coincidence.

Moving back to the original question, Zenoah engines are still well made engines that are as reliable as a stone axe. They only have two weaknesses. They are converted industrial engines and therefore are heavier than they have to be to get the job done. Also, the lack of ignition advance robs them of ultimate power. The latter can be fixed by using a CH ignition. Depending on your static balance situation and power required these issues may not even be a problem.

Same part numbers, same everthing and it is all interchangable as far as the gassers go, only different one is the mag case Pro

RE: evolution engines?
 

go ahead and get a 3w 28i and be done with it.

anything else and your ******* in the wind[sm=greedy.gif]

RE: evolution engines?
 

For everyone's informaion.

EVO engines are made in Spain and are not MVVS or Evolution, the MVVS is made in the Czech repuplic, they also make the Evolution engine for Horrizon to Horizons specification, also they make the Graupner version for the German market to Graupners specifaction, the only Magnezium engine is the MVVS45, the MVVS 58Pro which is the only Pro made and and does not have a magnezium crankcase.

Vagabond....I've had plenty of experience with a local Decathlon on floats, AUW 20lbs...and the completely stock G26 yanks it around significantly better than scale. Appropriately propped, and with a decent aftermarket muffler, the G26 will not let you down, or your son, or your grandson...and so on, you get my poing right? These things have certainly earned the right to be tagged 'bulletproof' when properly cared for.

Hi friend,

do you know where is place of production Evolution 26,35,45,58 and 116 ccm?

RE: evolution engines?
 

Here: http://www.mvvs.cz even the water cooled 58 version.

in this entire thread, ive seen only one guy who liks the evo gassers. i know they are not good engines, im glad to see they havent fooled anyone.:D

RE: evolution engines?
 

Friend,

I know. I have this engine.

RE: evolution engines?
 

Hi!
EVO is a Spanish engine brand.
Evolution/MVVS is a Czech brand ...made in Czechrepublic...not in China. These are some of the best gas engines on the market.

RE: evolution engines?
 

[:@]Evolution glow engine made in China...some of the not so best engines on the market. They should be the next recall of the growing list of Chinese products deemed unworthy in the States.[:@]

Not knocking their gas engines, mind you, I've not owned any. I only speak from experience.

RE: evolution engines?
 

I'll throw my 2 cents in. I have a Evolution 26GT2 and I really like it. Runs great, nice transition. I like using a 2 cell Lipo for the ignition, more capacity, less weight. I also agree that the carb is in a tough position and mine is sometimes hard to prime. I think the prime problem is related to how difficult it is to get at the carb to manually shut the choke and hold it, wish it wasn't spring loaded. I'm flying it on a new Wildhare edge25% and it has a ton of power even with the stock muffler. It also burns very little fuel.

James- I saw a 26GT run on a H9 Hellcat. It was a good running engine.

outacontrol41- I have to disagree with you on the Evolution (aka Evo) glow engines. They are high quality products. Even Clarence Lee agrees. I would put the .46NT on a higher scale than the OS .46FX as I've had both engines on the same model. No comparison!

RE: evolution engines?
 

BLW----I have 2 Evolution engines a52 and a 46. The reason why I dont trust the motor is because of the low speed lever thingy---every time I get it adjusted ,,,vibration from the engine moves it ever so slightly enough to throw it off. Seems like there isnt enough resistance to hold it solidly in place..Other than that I have no problem with it. My props are balanced.

RE: evolution engines?
 

might try extending the spring, to put more pressure on it.

RE: evolution engines?
 

Yes, I've heard of that happening to some engines. It's never happened to mine or the ones I've been around. For a quick fix, I would tie off the adjusting bar on the collar so it doesn't move and use the normal ls adjustment screw. I took the collars off of mine.

Sorry about this being about glow in a gas forum.
