evolution engines?
 

Im putting together a Super Giant Decathlon,,,,,,,,,,,,,,,,,,,,Now its engine time . I was considering a Zenoah G-38. But I am eyeing one of those Evolution 35GT2, seems to be a bit lighter. Does anyone have one of these motors. Are they pretty reliable? Im really partial to Zenoah---second choice would be Evolution ,although Ive never had an Evolution gasser,,Ive had a couple of Evolution 2-strokes,,they are okay. Just curious about the Evolution gassers.

Any help would be greatly appreciated
THANKS--JIM

a friend of mine has the 26. if the 35 is anything like it you dont want it. they look alike and may have more then looks in common. evolution or zenoah is not even a contest. good luck.

RE: evolution engines?
 

I dont quite understand what you are saying,,could you clarify for me? thanks--JIM[sm=confused.gif]

RE: evolution engines?
 

The only thing the Evolution stands for is your mental state from before buying the engine to the after spending the money...you evolved from dumb to inteligent (in what engines NOT to buy). I have the 26GT and is only good for the target practice!

RE: evolution engines?
 

I don't get it, isn't the Evolution engines the same engines as the MVVS engines, my MVVS 35 is a little monster, it may not be as powerful as a top of the line 40cc but it put my G38 to shame, big time..

I have three MVVS gas engines and they perform flawlesly, start easy, run reliable, frugall, and more powerfull than other engines on site of similar displacement, some people have problems some don't, it generally turns out to be self made problems and the engine gets the blame, most common problem is using a two pipe tank system and the one way valve in the feed tube not working correctly, using a three pipe system has eleviated more problems in this gas forum than I can count, next most common problem is using too low a voltage ignition battery, check the manual, next is dirt in the carb, filter fuel going into and out of your fuel carry container and put a felt clunk in the tank, that should be all thats needed, don't put another filter in the feed line its asking for another problem, next leaking fuel tubes allowing air into the system, the tubes from the tank need barbs on them to stop the tygon slipping off, zip tye the tube behind the barb, I use a soft wire wrapped around the tube and solder it onto the pipe (paper clip wire) don't forgett the tygon on the inside of the tank for the feed tube, barb and zip tye as well.

I am so satisfied with the MVVS engine's I am about to buy another, back up and service from Pe Reivers in Holland is the best I have ever had on anything in Aeromodelling, look on the MVVS Support Thread here on RCU and you will see what I mean.

Hope this gives a better ballance on the perceived opinions on gas engines and MVVS in particular. Incidently all of the problems listed above have been on all the different makes of gas engines, not isolated to one or another.

RE: evolution engines?
 

i dont know the similaraties between mvvs and evolution. let me clarify just on the evolution name brand here. my buddy bought one----- ITS EXPENSIVE 400 PLUS. the motor is an obvious conversion. it was not born a gas motor. it has an aluminum rod with a bearing pressed into it., its internals are small and light weight, not what you want for a gas motor. it has no internal mass to devalop the torch of a gas motor with a dual countrweight crank. its always out of adjustment so it seems and has an adapter to mount the carb. the carb is in a horrible spot to close to the prop. the ignition leaves somthing to be desired. it went up in smoke on the first flights. the battery used can be a higher voltage, but only on the 26 version2. used with the version 1 ignition will fry the ignition unit. basicly you will never get the reliability, durability or long term power of a steel rod dual throw gas motor. dont waste your money.

RE: evolution engines?
 

The one item I have heard from reading feedback about the Evolution engines, is that without their tuned pipe: http://www.horizonhobby.com/Products...D=EVO30984268E they really don't hold their own in the performance department. And WITH the tuned pipe and its additional weight, along with the money invested, it narrows the margin between any idea of saving weight or getting more power out of a smaller, lighter package as compared to the Zenoah or other similar options available, making it a not-so-attractive option any longer.

If you would like to save some weight compared to the Zenoah g38, and still have the great performance and longevity qualities, look into the Brillelli 36GT. It is a VERY reasonable value for what you get, and Scott is a great guy to work with.

good luck!

RE: evolution engines?
 

I bought the Evolution 1.00NX two stroke. No more Evo engines for me. After a long time of breaking it in and tinkering with it trying to get it to run right...the carb fell apart.[:@][:'(] That was enough for me.

RE: evolution engines?
 

Evolution Gas engines are MVVS engines renamed by Horizon hobbies. There are no connection to Evolution glow engines!!! Well those glow motors are not so bad either, but carb settings are little complex for average Joe.

MVVS/Evolution are nice engines if you read the manual and take a moment to learn your engine behavior. Maybe Zenoah run better out of the box and you can throw the manual to rubbish bin...

MVVS/Evolution 35 is a little bit too heavy for a 35 engine and MVVS 45MG is actually lighter. 26/35 works best with a tuned pipe. If you are not using pipe and side carb works for you, look for Brillelli engines. Horizonhobbies has a poor support for Evolution gassers, but if you buy your engine from Pe Reivers(www.mvvs.nl) there is a MVVS support and also a forum here in RCU.

Zenoah is a bit heavy, oldish and not so powerful engine anyway...

RE: evolution engines?
 

"Oldish"?? LOL:D:D Evolution can only hope and pray to become "oldish" some day. Time will tell.

EVOLUTION IS NOT THE BURNED OIL THAT ROLLS OUT OF A ZENOAHS PIPE.[X(]

RE: evolution engines?
 

:) We've heard all of the stories about Zenoah being overweight, underpowered boat anchors. There is thread after thread after thread regarding such comments. Most boil down to a realization that many folks are comparing EI engines of a smaller displacement to the zenoah with mag ignition, and use weight as the overall deciding factor. A very common comparison would be the G62 to the latest 50cc engines out there. This is not an adequate comparison at all. The cost of some newer EI engines is still higher than getting yourself a zenoah, converting it to EI, losing a pound or more of weight, and then you have something to compare to. Put any 26cc next to the G26, equipped with EI and a properly tuned pipe setup, and prop for best thrust (mezjlik 18x6) and see how things compare. Can every 26cc engine readily available for our hobby spin that prop on a pipe at 10 grand? What you'll find is that most don't measure up to the virtually bullet proof zenoah, and those that do measure up, don't win the battle because they are significantly more expensive by comparison. Even in the unfortunate event that both engines dirt dive....you just can't beat the readily available replacement parts for the Zenoah, available through various sources, rather than having a limited source for parts, and finding that they are more costly to replace. I'm not strictly a Zenoah fan....I have a thing for 3W's, ZDZ's and the new DL as well. I don't happen to have any DA, but I know they are a good product. Bottom line is, when setting up the engines to compare 'apples to apples'....Zenoah has a very competitive place in this market, and has proven itself worthy of maintaining a good name respectively.

Just anothe quick one, EVO are a spanish manuafacturer of engines, Evolution are re-badged MVVS, the 45 is just under 3Lb without ignition, all this talk of lightest engines is a misnoma, I have just completed an Extreme Composite Edge and had to put 3/4Lb of lead in the front to get the CofG in the recommended place, I just hope its nose heavy when I enventually get to fly it so I can take some out.

After all all these little forum trolls + mr CAPSLOCK, it would be refreshing that original poster would go electric...

RE: evolution engines?
 

Evolution engines are marketed by the same company that makes the Evo glow, Magnum, and ASP engines.

RE: evolution engines?
 

Come to think of it....I'M GETTING OLDISH![&o]

RE: evolution engines?
 

I agree completly. pound for pound and dollar for dollar along with the reliability and easy to get cheap parts, zenoah is second to none. compare a crank assy from a fuji b86 to a zenoah gt-80. the bt-86 part has clearly less quality with pressed in rod bearings and a more unfinished look. both motors are 800.00 new. the fuji crank is 450.00 the zenoah crank is 86 bucks. who are we trying to fool here?[:-]

RE: evolution engines?
 

Ahhhhh....for a minute there I didn't believe I had any followers with my comments. Thanks 540horses! I'm glad others have taken the time to look at how some items are marketed, and what you are actually getting for your dollar :)

Chad

RE: evolution engines?
 

Thanks guys,, I think my best bet will be the G-38,,,,,and you are right the price is a little out of whack especially when they dont even include a muffler. As far a

s the weight is concerned,,Ill have no problem with that. JIM

RE: evolution engines?
 

Hey WASP---Do you know Don Berg---JIM

RE: evolution engines?
 

Do you want me to throw a curve at this...and get you thinking? :)

Did you know that the available thrust from a G26 on it's best prop and muffler is only very slightly different than that of a G38 similarly setup? Ever wonder why most places charge the same price for the G26 and the G38? :) Things that make you go hmmmmmmmmm

Have a good weekend guys!

RE: evolution engines?
 

arobatx...you got me thinkin'.... there's really not that much difference![:-]:eek:

RE: evolution engines?
 

Hmm! I to will be putting together a Super Decathlon, mine is from coming from WWW.RCGuys.com . When I asked them as to the best motor, I was informed that the Evolution GT-26 was the best choice for it. I have a new Zenoah G-26 but was informed that it was to small and heavy for their plane and that a G-38 was not much better a choice. All I really want is a nice plane to fly and learn some basic aerobatics that it is capable of. Now I am so totally confused I will have to take a wait and see stance to see what works with this airframe. I could really use some good help here. Thanks, Jon

RE: evolution engines?
 

Poo poo on whoever told you a G38 or G26 was a bad choice. Want some trouble? Get a Evo GT-26. Do a search on Evolution engines on this forum...do yourself a favor and do some research. Use your Zenoah engines and let the guys pushing other engines use them themselves. Zenoahs are very reliable...I know...I own several.;)
FYI...I'd put the G26 on it - if it comes out 15 - 16 pounds you'll have a blast doing scale-like aerobatics.

RE: evolution engines?
 

;)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.

RE: evolution engines?
 

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.

RE: evolution engines?
 

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.

RE: evolution engines?
 

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.

Mike

RE: evolution engines?
 

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.

RE: evolution engines?
 

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.
