JC EVO Engines
Just wanted to tell you guys the experience of my JC EVO engine.. I have been running a JC EVO 120cc twin on my 36% sbach for testing.. It replaced an old 3w 106 TOC.. Already more power!! The engine is lighter in weight as well..The cylinder deign is totally new and the latest version and is like none other. I truly believe they will be the flagship china engines.. It has touch more power than the similar 111cc china engine and is lighter. We have also tested the 23cc and 30cc with great success and am currently working on testing a 60cc single!!. All have a billet 771 machined crankcase and as always includes standoff mufflers, ect. Below are videos of me piloting the JC 120 and JC 30. Enjoy..

RE: JC EVO Engines
There is a bit of history on these engines.. Good and bad.. Mine are still in testing and have found positive results. I do believe Kevin to finnally understand quality.. I however will wring these out until I know they are good. That is why they are not available to sell yet by me. Thanks

Hi Colin,
The offer still stands, if you want me to take a look at your 28 I will do it willingly.

RE: JC EVO Engines
Thanks paul!
TBH, the dle 30 is going SO well that I doubt i'll be needing the services of the JC. But thanks again for the offer!!
The difference really has been night and day.
I´ve stored it for another day incase I change my mind, if this happens you´ll be the first to hear about it!!
Also I do wish to make it perfectly clear, I am not saying all jc's are crap and get X brand instead.
Just that MY jc28 gave me problems. NOT that all jc28s give problems.

I wish JC would´ve concentrated more on building my JC28 well rather than designing new engines....

I think Paul and Kevin have told you more than one time they would take care of it if you would send it to Paul, So it looks to me like they are very concentrated on building your engine.
What else can you ask for.

The bark is gone with only a slight loss of power.... I'm happier than ever.

RE: JC EVO Engines
So who is selling these engines now??
I bought mine last year in June i think ( jc60 ) From planeaddicts.com it is my understanding that they stopped selling all the jc engines.
I was absolutely in love with it for about 4 gallons of use and then it started to leak at the base gasket. So in looking at the cylinder I learned that the lining that JC uses in there cylinders is crap. Mind you your cylinder fins are different from what i have.. So I really hope they have addressed the lining issue. I love the design of the engines primarily because it has HUGE ports it was designed to pump a lot of air which translates to HP. Also I love the finish in the case but they had to top it off with a grossly thin lining that wont handle the abuse of ANY excess carbon so here Is my suggestion.. I looked at the pistons out of a da200 that has over 20 gallons of use and They were in pristine Condition from the perfect airplane engine loving oil that redline makes.. Here is a clip that shows proof of it.

Here is a pic taken through the exhaust port at the New Warrantied cylinder in my engine.
If i were you I'd put the redline in the mix now and just deal with the 15 gallon break in period.
Just my 2 cents of real world experience though.. Love the sbach by the way
Here is my bird..

RE: JC EVO Engines
I had to have mine warrantied and they did replace the cylinder .. the one in the pic above Check out how they addressed the leak issue I was having.. It was superb
Its awesome that they managed to make so much power using a dle55 piston, ring and conrod mounted to a 3mm stroked crank with monster ports

RE: JC EVO Engines
Was not me, If all is right there is no need for sealer on the cylinder gasket.
Can you show us a picture of the top of the cylinder.
Would like to see if it was replaced with one of the old style cylinders.

It is still working however. I looked at the piston last saturday and its still doing pretty good no carbon build up and only wearing on the bottom corners of the skirts.
We looked at it because it started rattling like it needs a crank bearing.
It was planeaddicts and just so you know I would still buy from them they were fast and fair. But i'll refrain from sending an engine that way.

RE: JC EVO Engines
milton, All i could find was the pics of the first tear down when I realized I had a bad carbon problem..
What kind of price would it be to have you put new crank bearings in for me.. i'll pm you my email address and phone number.

RE: JC EVO Engines
All it will cost you is the shipping cost both way's
The engine has to be still under warranty.
Might be a couple weeks, I should have parts by then.

RE: JC EVO Engines
Is that picture after the cylinder was replaced, if so it is still the old style cylinder.
Probably all they had at the time, New cylinders have only been available for the last couple months

I wouldn't really expect the parts to be free I didn't buy from you but that would certainly be cool though.
However I did modify the casting adges of the port bridges though... just to get rid of the flat spots.
I could include the original purchase info from paypal.
i'll give you a call at the shop sometime soon and follow up with a pic of the cylinder as it sits now. just to verify the version.

RE: JC EVO Engines
Nice Job Chad, the Sbach is one great airplane I truly love mine. Its only the Pilot 30% but flies in the same manner as yours does.
I did fly a smaller version up in Montanna last year and wasn't that impressed, seemed heavy,felt heavy too ! but I could have been the way the guy had it set up,All I know is I didn't have enough elev, or anything else for that matter. YA know one of them there deals when the only thing that goes closed to full is the throttle.

RE: JC EVO Engines
I was watching the plane so much I almost forgot to post on how well the engine seems to run and it has plenty of beans for that plane plus.
I think if things hold up you may just have a winner.
