No, they dont match up, they are off by about 1/4 inch. What i did was use the upper right hole and driller 3 new ones. You will also have to use the included blind nuts, the ones in the tana would work with their screws.

Has anyone found a prop nut or aluminum spinner that matches up with the output shaft? I cant find one that will screw down on the shaft

OkieTrucker,the prop shaft threads are 8x1.25mm. atsrcplanes.com has spinner type prop nuts that will fit your shaft.Rich

I have a question for all of you CRRC 26 owners, are you all running metal gear servos and is it necessary. I have an 11lbs plane extra with a super tiger 2300, a ridiculously high torque metal gear on rudder, 2 Hitec 475HB on elevator, and 2 hitec 475HB on ailerons. This setup works fine with the st 2300, but will it also work fine with the crrc 26? Looking at the numbers they put out about the same power, but I hear gassers shake a whole lot more and might strip non metal servos.

Jeff,
I strongly advice you change those 475HBs for 645MGs. (You may use the 475 for throttle). When dealing with gassers, ALWAYS use metal gear servos. Don't ask me how I know....

Ouch, you stripped a servo flying with a 26cc? I always use hitec HS311's on throttle, they work well and cost $9.

Well, I started flying my Extra with the 26cc CRRC Pro but ended up with a DL50. The servo ultimately stripped with the DL50 but I'm sure the 26 had something to do with it as I flew the smaller engine/475 combo 100 times, at least. I think getting a MG servo is cheap insurance. Hope you enjoy the 26cc, it's a great little engine if you fly 3d under 10 lbs.

Yes I plan on getting a lighter plane once I plant my portly cmp extra in the ground, but until then it should be a decent plane to figure this engine out with. A DL50 has WAAYYY more power then this little engine, would you say the crrc runs pretty smooth or is it a shaker.

Static thrust:

DL50 - 25-30lbs

CRRC26cc - 11-14lbs

Well, the 26 is pretty nice and not bad at all at shaking. It starts fairly easy and has plenty of power to fly my 75 inch ws Extra. It weighed just under 11 pounds so there was no much in the sense of punch out of a hover but still a competent performer.
Surprisingly, before I put the 26 in the nose, it had a ST2300 spinning a 18x6. Let me tell you that although the Tiger in theory has more HP (3.7 compared to 2.4 of the gasser) it quicks some royal glow fuel butt. The power the CRRC gives you is right where you want it, at low rpm. Once you try your Extra with the gasser, you will never go back to the ST2300. I still love my Supertigre but not for my Extra. It's probably better suited for a warbird or something like that. Definitely not a 3D engine.

Cool, glad to hear it, I've never had a plane before that can hold let alone pull out of a hover. So, I guess I'm not used to that level of power. When I get a plane that comes in under 10lbs it will be like learning to fly all over again.

There are so many planes out on the market for this engine now, cant wait. Take a look at these, both under 10lbs and over 70":

I thought I'd pass on I bought replacement NGK CMR7H spark plugs from Advance Auto Parts for $3.98 they only took 1 day to come in. They also stock pennzoil air cooled 2 cycle oil. Bob

What gap are you using? I picked up 2 of these today??

Here are some videos og the CRRC GF26I.
First videos is just a look.
Second video is numbers with an APC 17 X 6 prop..
Third video is an SY 16 X 8 prop.
In the third video, I could not believe how much putting the cowl on the plane affected the flight performance.
It was still OK, but with no cowling , it is an animal and has fast, unlimited verticle.
With the cowl verticle was still good but it sure wasn't fast.
I had trouble downloading the videos without the cowl, so when I take more I will post them.
Needless to say, the cowl looks good, but I think I'll keep it off.
By the way, in the third video, some goof ball forgot to turn on the Opto kill switch on the TX.

Always, always use metal gear servos on gasser.
The frequency of the vibration of a gasoline engine is much different the glow engines.
It is not the power of a gasoline engine that does it, you can use plastic gears in a 1.60FX glow without any issue.
The 1.60FX is more powerful then any 26cc gas engine.
It is the vibration of a gasser that kills plastic gear servos.
