Are 'Evolution' engines any good??
 

Hi guys,
Been reading up on the new Evolution engines, in particular the 1.00 to power my new CMPro extra 300s 90.. i was origionally going to just pbuy the OS 90fx but came across this and its had some awesome reviews and statements that quality is as good and in some cases better than OS.. is this true?? Thanks, james.

They are made in the same plane as the Magnum and ASP engines and have the same dimensions except for the .46. The Evo trainer engine is a match for the Magnum .46. The Evo .46 is a longer stroke, smaller bore engine and is closer to a .47. I have heard the 1.00 is a good engine, but tends to be on the heavy side.

I bought a Evo 61 engine to try. Using thee same size/type of prop the man claims to get 12,0000 rpm. I am lucky to get just over 11,000. Out of the box it was way too rich on the low speed. Fuel burbling out the top of the carb and would instantly die if I touched the throttle. After some adjustments it ran ok but not great and seemed to lose power with every flight. I have read more than few reports of this happening with other Evo engines as well. Brought the plane in, tyed down and throttle up to try and find out whats going on. At high throttle you could see the low speed idle knob turning! Pulled the engine and its sittting on one of my benches now. [>:]

Disclaimer: I have never used and Evolution engine, so take my opinion with a grain of salt.....

OK... there are a few people who use them at our field....
One is a good friend of mine... he had the .46 worked great on the test stand.... but never reliable in the air..and he (and the several other people who have helped) knows how to tune engines...
He is now borrowing my OS .46ax so he can fly...
The wierd thing is it ran fine last summer

another gentleman has an Evo .46 in a trainer..... if the temp is remotely cool... the engine will not run...and MANY people have tried tuning this engine...

Now, I'm not saying they are bad... and these may be very isolated instances related to cold weather flying....
but I don't think I would be in a hurry to grab one....

Just my very humble opinion

RE: Are 'Evolution' engines any good??
 

Thanks for the speedy words guys... looks like i am going the OS lol... can't beat 'guaranteed' reliability.

I'm going to throw a question out in the open here, is there anyone in the states that is will to help me with purchasing an engine from over there and shipping it here for me?? Due to the Aussie dollar at the moment being fairly strong, the US prices beat out RRP by a big margin, and have tried to buy through an online store, but there is only 2-3 major ones i can find, and was hoping maybe someone had a personal connection with a hobby store that could get a price for a desperate aussie after an OS powerplant ;) I say this because the Australian suppliers are out o f the 61 and 91fx, and whatever is here as old stock is going for the same price per ounce as gold! Let me know ;)

Everyone at our field that has the "Evolution engines" of any size say that they have nothing but trouble with them. Some have gave up on them and a few others are still tinkering with them. I personally run O.S., Saito, and Super Tigre engines.

Newbie at field has one in his trainer, a few friends and myself, all experienced modelers spent a frustrating afternoon trying to get it to run well, , most things were tried, we changed the plug, changed the prop, took off the restrictors on the needles in case that was the problem but nothing worked, it would start and pick up fine until mid throttle then just lean out and die. After about three hours of fiddling we abandoned it, one of the guys, who works for a model fuel company took it to his workshop and eventually found that the baffle in the muffler had a really small notch to allow the gases to pass into the second chamber, once this was opened out to a similar size to the tailpipe internal bore the problem was solved. I gave the newbie three flights last weekend, engine starts and runs well, no flameouts and seems to produce average power for a 46.

Dave, thankx for the heads up! When I had the mufflerof my 61 apart I noticed that there is baffle with very small passages as well. After reading your post I will take the muffler apart and see about making those openings bigger![8D]

I have one, and I'd get another in a heartbeat - Runs great

RE: Are 'Evolution' engines any good??
 

I have been selling these engines since they were first put on the market and have not had one problem. There is a post on RCU under glow that has the power of the 100. These engines are too easy to set and run. If someone is having trouble setting the engine, it's not the engines fault. Dennis

RE: Are 'Evolution' engines any good??
 

Run great but so do my mds's

RE: Are 'Evolution' engines any good??
 

Thats a pretty bold statement......

RE: Are 'Evolution' engines any good??
 

What about the engine is supposed to be broke in and set up with factory settings? My low speed needle valve was open way too much and I have read about several cases where the low speed valve was closed off completly! [>:]

RE: Are 'Evolution' engines any good??
 

I have owned the Evo trainer system engine and an NT .61. My brother had an Evo trainer system. Several people I fly with have Evo's in all different sizes. I have not seen nor experienced any of the problems discussed here. Maybe we're all just real lucky and got good ones, but I doubt that is the reason. I'd buy another one if I were in the market for a small 2 stroke.

RE: Are 'Evolution' engines any good??
 

Maybe its every 5th engine when the boss is watching that does get set up properly and runs great. If you get one of the other 4 engines, well good luck! From what I have seen and read they have a common characteristic with the Tower Hobbies engines. Some run great out of the box, some never run right.[8D]

RE: Are 'Evolution' engines any good??
 

I'm flying my trainer .45 for the second season. Last year I had a bit of trouble at first getting it to run correctly. I had several dead sticks at first but it has run well since. My only complaint is I can not keep the muffler from vibrating loose into 2 pieces, I've tried everything. I am going to JB Weld the halves together this weekend.

RE: Are 'Evolution' engines any good??
 

they are very good however i looked at there new gas line and they look exactly like mvvs engines!

RE: Are 'Evolution' engines any good??
 

My Evolution 100 on a Funtana 90 started right out of the box, idled and transitioned perfectly. Needed to lean the top end slightly, went flying. No problems, hovered the Funtana at 1/2 throttle with, shot skyward with ease. I am impressed with the engine.

LHS sells a lot of them, all have been trouble free. I agree with Dennis, it probably isn't the engines fault. However an occasional crapper can be had with any manufacturer, including OS.

RE: Are 'Evolution' engines any good??
 

Well... it seems to me like the engine iteself isn't to bad, its just the factory is inconsistant with factory settings?? As far as quality goes what are they like? Is the finish as good as the OS engines?

RE: Are 'Evolution' engines any good??
 

It seems no matter what, there is always some cheerful fellow that will tell people on here that they'd have to be an idiot not to be able to get something to work...

"If someone is having trouble setting the engine, it's not the engines fault. Dennis "

I thought the Evolution engines were factory run and pre-tuned so that even an idiot could get them to work. That is the marketing of them. Clearly there are folks that have not had the simple experience the engine promised, but it must not be the engine right? If the engine is a great performer but requires some addtional tuning to get that way, then it is still a failure based on the bold statements by marketing that anyone can get this engine going. How can the customer be a fool when the engine is fool proof? Maybe the customer is a fool by believing the marketing hype....

RE: Are 'Evolution' engines any good??
 

Thanks aviti for expressing my feelings so clearly, its amazing to me that some people on here always assume that people are somehow fools for expressing an opinion other than there own. I replied to the original posting with my findings on the particular engine that I had dealings with, those were my honest findings and I truly resent being told that Im somehow inadequate for not getting this engine to run.

RE: Are 'Evolution' engines any good??
 

Can't see where anyone is flaming others here. The valued opinions expressed illustrate a cross section of modelers's experiences with Evolution engines, thus allowing a reader to arrive at a conclusion as it pertains to them.

This hobby includes plenty of idiots who trash anything they touch, other idiots who claim to know everything, numerous idiots who never admit to a wrong, expert idiots, clueless idiots, helpless idiots, don't need your help idiots, and everyday idiots like me who have spent 40 years in this hobby with both good and bad experiences.

The Evolution engine series serves it's purpose and most idiots understand advertising claims are overexagerated. The engines are well made and finished and reasonably priced. In my case the 100 performed exactly as advertised and a number of local club members obtained equal results.

As in most instances on the web, complaints come first from the idiot having a problem, then others pile on. Then some other idiot comes and bursts the negative bubble by saying they love it and no problems exists. How dare them!

From one idiot to others, read the posts, evaluate, then make your own decisions about the Evolution engines.

RE: Are 'Evolution' engines any good??
 

I have 3 of the 45's, 2 - of the 40's, 3 of the 61's & just bought the 100. All of them run great, would recommend these engines to anyone.
My 61 on a H9 stick, out preforms a friends stick with a 76 on it!

RE: Are 'Evolution' engines any good??
 

Jolly good!, I repeat again I was merely expressing an opinion, I therefore bow to your superior knowledge and withdraw from this conversation.

RE: Are 'Evolution' engines any good??
 

davej78,

Don't miss the point here. Your experience with the engine, and the modification that solved it is just as valuable as those expressing a trouble free experience.

No product is perfect and those experiencing difficulty may find a solution among these posts.
