All:
Have any of you been using the CRRC 26 V2? If so what is the difference between it and the version 1 engine? How does the V2 engine compare against a zenoah G-26ei?

Thanks

Would like to know the answer to the same

Well I've been flying a CG Wild Stick 120 with a CRRC GF26 v2 and it flies great. The v2 had excellent power and transition. I flew against a v1 and it was a dog! The v2 uses rails to install like a glow engine whereas the v1 used 4 standoffs.

I have had the CRRC 26 V1 for a couple of years, and I am well pleased with the power and ease of use. IMO it is not a great engine, but a very good one. I have used a 17X6 prop mainly on an aerobatic plane with good results.

The Zenoah G26 is a great engine. It is the power standard for all the other 26cc engines. No other 26 matches it. To surpass it you need to go to a DLE 30. The knock on Zenoah is the weight. Sometimes, weight is critical, often it is not.

I have a Zenoah G20, an amazing little engine! It will do about everything my CRRC 26 can do but easier, and with less vibration.I also use a 17X6 prop on it. I paid $100 more for the G20 than for the CRRC, and I feel I have a good value in each.

Its a win-win.

I have a CRRC26 V2. I'm going to put it on a Seagull 1.20 Decathlon. I have only run it about 2hrs. on the test stand. Seems to be a good engine for the money. A positive is the single prop shaft. I also like the glow-type mounting rails. My only kick is the spring loaded choke, but that is easily disconnected. It also has a straight-up, tall plug that will stick below a lot of cowls. I even put an 18-10 prop on it for a short,experimental run. The 26 ran it, but would probably overheat in service.

The only difference between the CRRC26CCV1 and the V2 is the mounting system and the length of the crank case as far as I know.Check the CRRC website and see this. They are the same engine with the same specs except for measurements, The V2 is not like a new updated improved version just different measurements. The V2 islonger and kind of looks like a nitro block.V2 uses traditionaltype engine mounts(included) andtheV1 mounts to planes withthewood engine mount box with standoffs (included) ifnecessary.
I'm going with the V1 in my CMpro Marathon looks like it is made for it and will fit nicely inside the cowl.

I finally flew the 78in. Decathlon. The 26v2 pulled it fine. Has good takeoff power and climbout with a 16X8. I'm going to try some more props when the weather improves and I get a little more time on the engine. I disconnected the choke spring but full throttle sucked the choke shut. Duh-huh!!! It either needs a servo or pushrod to hold it open without the spring. I got it started by putting my hand over the velocity stack and choking it that way. Then turn on the ignition and flip. Works fine. The metal mounting rails can interfere with the throttle pushrod, but it is nothing a drill won't fix. Vertical with the 16x8 isn't forever, but it will do more than enough for a good high Hammerhead turn and big loops. I don't feel the need to pay more for the incremental hp increase of a Zenoah.

You are wrong:
There are MANY difference between CRRC GF26I and the GF26V2 :
Crankcase, crankshaft, bearings, con-rod, needle bearing, seat, propeller hub .... are different. Cylinder is almost the same.
Also there are TWO versions of cranckcase and crankshaft for the V2 and GPR engine , improved now to mount a bigger rear bearing, and NO seal on last version of GF26Iv2/GP26R, but both bearings are sealed now.

I think he means operationally they are the same i.e. port timing, compression and carb are similar/same. Similar prop, weight and power.

It is a copy of a G26 anyhoo.

16*8 seems perfect prop. Much more power than the melody/SPE 26. It gives slightly less power than a 4stroke 180 glow on an 18*8. As expected, the 4s 180 converted to petrol on 16*8 gives a bit less than the CRRC on a 16*8.



Very pleased with mine.

Yes, operationally the same, and is there any reason one would out perform the other? What I was saying is I don't think there is any component that makes one a higher performing engine than the other. And where the heck do you get those specs of crank and bearings etc. I have a heck of a time just finding basic physical dimension diffs on all the different Chinese engines!

Wow! I ordered the CRRC v1 on Monday and I got it  from China today Thursday! Unbelievable! Via DHL air! got it from this site called ECrater.  The engine was $155  shipped, unreal. It's the real thing, packed neatly in original box, tool, and when I opened up the box it reeked of gas. So they really do test them at the factory!</p>
