CRRC Pro GF26I

[MTS247]

Mine does that same high idle thing and then drops really low and stalls. but it idles very high at start up, even if i taxi around a bit it wont come down. so as a result i lower the idle because i dont want a fast landing. but then on aproch im bliping the throttle to stop it stalling. It also has an ocasional misfire sort of thing when flying around but it hasnt caused it to stop, yet.
NKG plug, rcexl ignition,

I have checked the gaskets but i'll check again.

Is the ignition module case made of some kind of special RF blocker? I was wondering because I cracked a piece out of the bottom of the case. Does the case serve some other purpose? I have another ignition module, but I was wondering if the cracked one is still flyable??

It's made of nickle plated plastic and yes, the plating is for RFI supression. Range test it with the engine running to see if gives off any RFI.

Thanks, will do. Oh, one more question... what does the black goo do?

[Jedijody]

Vibration resistance, and keeps the kids from poking around in there with screw drivers.

[3Dguy]

Awww man. And BTW, I also have a soldering iron!

lol

I just found this...It must be from CRRC's high-budget, top secret lab. I don't think the second vid shows a 26gfi, though...

Good numbers.

We want pipe!

Just a followup to many peoples experience with this little engine.

I got my CRRC 26cc last fall as my first gasser so only test ran it a bit, only to find out some quality issues

1/ the pulse channel was not drilled in the carb body ( I suspect the body was for a remote line pulse type) anyway Idrilled that through.
2/ the base of the cylinder had a gap where it bolted to the crankcase as the front and rear halves did not meet equally, I filed the case flat and reassembled the engine with motorcycle RTV sealant.
3/ the ring takes forever to seat so there is not enough compression to hand start , I used an electric starter to get it started the first 25 times.

Now it runs perfectly, although not the smoothest ever, it has lots of power in my East RC 72" Yak, pulls straight up as far as you want at 1/2 throttle, Turns 8900 rpm with a 17X6 APC or 16x8.

I'll order soon! I gotta get a plane flying. Are there any vids of this engine/muffler on a plane?

[Jedijody]

Not yet, I'm working on it though.

BTW, the engine in the second video is a GF26I V-2, same top end and carb, different crankcase and crankshaft designed for profile planes. Will be out in a couple weeks, I've been testing one for a month or so and it's performance is the same as the regular 26 but has less vibration due to the new crankshaft design.

[3Dguy]

What are you putting it on?

[Jedijody]

Not sure yet, either a 1.20 size Goldgerg Wild Stick or a Aviation Models 1.10 sized profile Yak, which ever needs the least modification.

[3Dguy]

Can't wait to see it.

Hey Jody
Thanks for the tips on the electrics ,
Here is my new Hot Rod for 3D Practice, Just got the engine started last sat and ran 1 tank through it on the ground over the course of a day just in 3-5 min intervals so it wouldn't get over heated and try to seat the ring a bit , But have to admit it was a Pain to get it to fire at first had to use an elec starter . will maiden this sunday, But first I will open up the louveres with a dremel tomorrow,and will add a Pilot and fill cock pit in the comming weeks , I'm useing HD servos all round + 2 A123s for the elect and ign, will get weight on it tomorrow cg is spot on the back edge of wing tube hope that is Ok will soon find out , I will defeniately have sweaty fingers when taking off,
